U.S. and International Health Responses to the Ebola Outbreak in West Africa
Summary
In March 2014, an Ebola Virus Disease (EVD) outbreak was reported in Guinea, West Africa. The
outbreak is the first in West Africa and has caused an unprecedented number of cases and deaths.
The outbreak is continuing to spread in Guinea, Sierra Leone, and Liberia (the “affected
countries”); it has been contained in Nigeria and Senegal, and has been detected in Mali. As of
October 22, 2014, more than 10,000 people have contracted EVD, more than half of whom have
died.
Until October 2014, no secondary EVD cases had occurred outside of Africa. That month, health
workers in Spain and the United States contracted EVD cases while providing care for Ebola
patients. Other factors make this outbreak unique, including
•
its introduction into West Africa;
•
multi-country outbreaks occurring simultaneously;
•
disease transmission within urban areas; and
•
an unprecedented scale and pace of transmission.
In the aggregate, between 1976, when Ebola was first identified, through 2012, there were 2,387
cases, including 1,590 deaths, all in Central and East Africa. The number of Ebola cases in this
outbreak is four times higher than the combined total of all prior outbreaks, and the number of
cases is doubling monthly. The U.S. Centers for Disease Control and Prevention (CDC) and the
World Health Organization (WHO) have projected an exponential increase in cases. WHO
estimated that by the end of November, some 20,000 people may contract Ebola; CDC estimated
that “without additional interventions or changes in community behavior,” up to 1.4 million could
contract EVD in Liberia and Sierra Leone by January 2015. CDC indicates, however, that the
outbreak may not reach such proportions since responses are intensifying. In Liberia, for
example, improvements in burial practices have resulted in roughly 85% of all bodies being
collected within 24 hours of being reported to national officials.
In an August 2014 report, WHO estimated that it would cost roughly $500 million to contain the
outbreak by January. In September, international responses accelerated. The United Nations
(U.N.) established the United Nations Mission for Ebola Emergency Response (UNMEER) “to
utilize the assets of all relevant U.N. agencies” to address the health and broader social impacts of
the outbreak. A proposed U.N. response would cost roughly $1 billion, about half of which would
be aimed at addressing health impacts.
The United States is the leading funder of the international Ebola response, and its financial
support is growing. As of October 25, almost 900 U.S. government personnel had deployed to the
region, and some 4,000 military personnel will be deployed to the region. The U.S. Agency for
International Development (USAID) reports that as of October 22, U.S. funding for EVD
responses totaled $344.6 million. In addition, the Department of Defense (DOD) is planning to
spend more than $1 billion on EVD activities in West Africa. On October 17, President Obama
established an Ebola Czar to coordinate U.S. domestic and global responses to the Ebola
outbreak.
Some global health experts have criticized the U.S. and international response to the Ebola
outbreak, decrying the pace and scale of assistance. The limited impact of U.S. and international
Congressional Research Service
U.S. and International Health Responses to the Ebola Outbreak in West Africa
responses to the Ebola outbreak has raised several questions regarding global health governance
structures, international commitment to bolstering pandemic preparedness and response capacity
in poor countries, and global support for strengthening health systems. The international
community lacks a rapid response team of health professionals prepared to address health
emergencies like the ongoing West African Ebola outbreak. Debates about whether WHO should
have such capacity have been at the heart of recent WHO reform debates.
While deliberating the appropriate response to ongoing Ebola outbreak, Congress is likely to
discuss the breadth of health, social, economic, development, and security challenges that this
outbreak is causing, as well as how U.S. global health aid is apportioned. This report focuses on
the health impacts of the outbreak and discusses U.S. and international responses to those health
challenges.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Background
Ebola virus disease (Ebola, or EVD) is a severe, often fatal disease that was first detected in the
Democratic Republic of the Congo (DRC) in 1976.1 Originating in animals, EVD is spread to and
among humans through contact with the blood, other bodily fluids, organs, and corpses of those
infected. It is not transmitted through the air, and the World Health Organization (WHO)
maintains that there is minimal risk of contracting EVD on a plane,2 though most airlines have
suspended flights to and from the affected countries.3
In March 2014, an EVD outbreak was reported in Guinea, West Africa. The outbreak is the first in
West Africa and has become the largest, most persistent ever documented. The outbreak is
continuing to spread in Guinea, Sierra Leone, and Liberia (“affected countries”) and has ended in
Nigeria and Senegal, after having infected 20 people in Nigeria and one in Senegal. As of late
October, nearly 10,000 people have contracted EVD, of whom almost 5,000 have died (Figure
1). WHO regularly updates EVD cases at http://www.who.int/ebola.
Figure 1. Ebola Outbreaks: 1976-2014, as Reported on October 22, 2014

Due to inadequate disease surveillance capacities in the region, WHO estimates that actual cases
may be two to four times higher than reported.4 Some health experts are concerned that the weak
surveillance systems in neighboring countries may miss EVD cases. On October 23, Mali
reported its first EVD case and some suspect that Cote d’Ivoire may have undetected cases.5
WHO is reportedly sending a team to Mali to help with clinical management, epidemiology,
contact tracing and social mobilization.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Ebola Care and Treatment
There are no drugs proven to prevent or treat EVD, though efforts are underway to develop them.
In October, press reports indicated that WHO planned to begin testing two Ebola vaccines in
January on some 20,000 health workers and other volunteers. The organization also indicated that
a treatment might be available for use in Liberia by early November.6 In the absence of specific
treatments, health practitioners treat EVD symptoms with supportive care, which can reduce the
fatality rate. Spread of the disease can be limited through the use of disease surveillance and
containment measures. WHO has released manuals that outline appropriate patient care,
management of contaminated objects, safe burial practices, and diagnostic protocol.7 These
measures successfully contained all the previous Ebola outbreaks.
Distinguishing Factors
The Ebola virus that is circulating in West Africa is not new. Health experts are familiar with
methods to treat and contain it. The disease is spreading quickly, however, because the health
systems in the affected countries are ill-equipped to implement requisite disease containment and
surveillance measures. Key factors that distinguish this outbreak from previous EVD outbreaks
include the following:
Emergence in West Africa. Prior to the current outbreak in Guinea, Liberia, and Sierra Leone
(affected countries), EVD outbreaks were concentrated in the DRC, Gabon, Sudan South Sudan,
and Uganda (Figure 3).
Simultaneous multi-country outbreaks. Disease transmission along the shared borders of
Guinea, Liberia, and Sierra Leone has been intense and despite efforts to detect the disease at the
borders, people infected with Ebola have imported the disease into other countries. Contact
tracing and disease containment have halted the spread in Senegal and Nigeria where the outbreak
ended on October 17 and 19, respectively. In Nigeria, an imported case resulted in an outbreak
that infected 20 people and killed eight. A single imported case in Senegal was contained to the
index case. WHO is investigating a new EVD case in Mali.
Until October, no EVD cases outside of Africa resulted in secondary cases. In that month, health
workers in the United States and Spain contracted EVD while caring for EVD patients. No
additional cases have been reported from the health workers. No other reports have emerged of
EVD spreading in other countries where EVD patients have been evacuated.
Cases in urban areas. Previous outbreaks were confined to rural and forested areas, whereas the
current outbreak is spreading in rural and urban settings alike. Responders are struggling to
isolate cases and contain the outbreak in densely populated urban areas that lack sufficient access
to clean water and sanitation and face severe shortages of health workers and clinics.
Scale and pace of transmission. Ebola is spreading at an unprecedented rate in the affected
countries. In Liberia, reported cases are doubling every 15-20 days and in Sierra Leone, reported

cases are doubling every 30-40 days.8 Health experts link the unabated spread of EVD in the
affected countries to weak health systems.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Unrelated, Ongoing Ebola Outbreak
A separate Ebola outbreak that is unrelated to the ongoing West Africa outbreak was detected in
the DRC on August 24, 2014.9 It reportedly began in late July or early August, when a woman
contracted an EVD-like hemorrhagic fever after butchering a wild animal. She later died and
infected several others. As of October 20, there have been 66 cases and 49 deaths in the DRC,
including eight deaths among health workers. All but five of the 1,121 contacts have completed
the 21-day follow-up period.10 This is the seventh outbreak of EVD in the DRC since 1976.
Congressional Actions
Congressional actions to address the outbreak have been accelerating. Several committees have
convened hearings on the Ebola outbreak and in July and September 2014, U.S. Representative
Karen Bass and Senator Christopher Coons introduced legislation recognizing the severe impacts
and threats of the outbreak.11 Also in September, Congress enacted legislation (P.L. 113-164,
Continuing Appropriations Resolution, 2015) that provided $88 million for the Ebola response:
$30 million for CDC Ebola response activities in West Africa and $58 million for research and
development of specific treatments and vaccines for Ebola. Congress has also permitted the
Department of Defense (DOD) to reprogram roughly $750 million of FY2014 Overseas
Humanitarian Disaster and Civic Aid (OHDACA) funds to build 17 Ebola treatment units (ETUs)
in Liberia and to support ongoing U.S. efforts in the region (see “Department of Defense”). For
more information on DOD responses to the Ebola outbreak, see CRS Report IN10152, Increased
Department of Defense Role in U.S. Ebola Response, by (name redacted).
Health System Constraints in Affected Countries
The health systems in the affected countries were already weak before the Ebola outbreak, and
have become overwhelmed by the crisis. According to WHO, there are six components of a
health system: (1) human resources; (2) governance and leadership; (3) financing; (4)
commodities and supply chain networkers; (5) service delivery; and (6) information.12 The
affected countries face severe deficiencies in each of these areas and the outbreak is exacerbating
these challenges. This section describes how constraints in each component of the affected
countries’ health systems enable the virus to continue to spread. Table 1 summarizes these issues.

Governance and Leadership
The unabated spread of the outbreak in the affected countries has contributed to perceptions of
government ineptitude. Mistrust of public officials has prompted many civilians to ignore or resist
government responses. Reports of attacks on health workers and health facilities (run by nongovernmental organization and national health ministries alike) persist. The affected governments
have used armed forces to enforce disease control measures and to quarantine neighborhoods,
further deepening public resentment. Some have questioned the effectiveness of quarantines and
criticized the measures, citing concerns about human rights, food scarcity, and possible unrest.
Following criticisms by health experts and protests, Liberia and Sierra Leone have stopped
quarantining some neighborhoods, though some quarantine zones remain. Despite concerns about
quarantine practices, Sierra Leonean officials had characterized a three-day “Stay Home House to
House” sensitization campaign a success, noting during which 92 bodies had been recovered and
56 Ebola cases were detected.13
Financing
Per capita health spending in Guinea, Liberia, and Sierra Leone has been relatively low (Table 2),
contributing to poor conditions of publicly-funded health facilities. Health workers and other
government personnel often experience delays in compensation and benefits, contributing to
absenteeism and human worker shortages. As the Ebola outbreak intensified, some health workers
abandoned their posts, citing not only safety concerns (from lack of protective equipment) but

also frustration over not receiving salaries. Several local staff at Ebola treatment units in Liberia
had reportedly not been paid for three months.14 Donors, including the United States, have since
begun to offer financial aid to Liberia to support payment of health workers salaries and other
financial incentives.

All of the outbreak-affected countries lack sufficient financial resources to fund their national
Ebola response plans and need financial support. Several donors have pledged to provide support
to the affected countries, though gaps persist (see “International Health Responses”). To meet the
health and secondary effects of the outbreak, the United Nations estimates that it will cost Guinea
$194 million, Liberia, $473 million, and Sierra Leone $220 million. Roughly half of these
resources will be needed for addressing health needs.15
Human Resources
Due to severe shortages of health workers and clinics, the majority of people infected with Ebola
in Liberia are without access to medical care and treatment. Inadequate access to health personnel
and facilities is also a problem in Sierra Leone and Guinea. Human resource constraints and
concerns about conditions in health centers are prompting people to care for the ill on their own,
facilitating the spread of the virus. The shortage of medics and health facilities also means that
people needing care for non-EVD related issues have nowhere to go.
Observers are troubled not only by inadequate access to Ebola care but also to the impact that
clinic closures are having on broader health issues, particularly maternal and child health. Before
the outbreak, maternal and child mortality rates in the EVD-affected countries were among the
highest in the world (Figure 3). In 2012, roughly 26% of all maternal deaths in sub-Saharan
Africa occurred in the four countries, where more than 46,000 women died from pregnancyrelated complications (an average of 126 daily deaths).16 Also in 2012, nearly 1 million children
died in the affected countries before reaching their fifth birthday, accounting for roughly 30% of

constraints. According to the United Nations, “[m]ore people are now dying in Liberia from
treatable ailments and common medical conditions than from Ebola.”18
High maternal and child mortality rates in the
affected countries are linked to the dearth of
health workers in the affected countries.
Between 2006 and 2013, Sierra Leone had
only two doctors per 100,000 people,
according to the WHO (Figure 4).19 At an
August 2014 congressional hearing, one
witness testified that prior to the Ebola
outbreak, Liberia had fewer than 200
doctors.20 After the outbreak, he estimated
that about 50 doctors remained to provide
clinical care, due in part to the evacuation of
several expatriate doctors. EVD deaths
among health workers have further
diminished these staffing levels. On October
22, WHO reported that 443 health workers
had contracted EVD, of whom 244 died.21
More than 40% of these deaths occurred in
Liberia. Sierra Leone and Liberia face
shortages that are much more severe than
Nigeria and the rest of the world.

Service Delivery
The Ebola outbreak has further diminished healthcare
options in the affected countries. Many health facilities in
Liberia and Sierra Leone are closed. Even before the
outbreak, access to clinics was limited. The vast majority
of health facilities are concentrated in urban areas and
Ebola treatment centers are concentrated in high
prevalence areas, leaving large swaths of the population
without access to both general healthcare and Ebolaspecific treatment. Due to limited access to clinics, the ill
frequently travel great distances in search of healthcare,
prompting most to wait until health complications are
severe. Delayed health-seeking practices are reducing
survival prospects among those sickened by Ebola and
encumbering efforts to detect and contain the virus.
Figure 5. Bed Capacity in Ebola
Treatment Units by Country
(as of October 18-19, 2014)
A variety of health services are needed to control the
outbreak, including Ebola treatment centers, laboratories,
contact tracing, and safe burial services. All of the affected
countries face severe deficiencies in these areas. Most of
the health services are unable to meet the demands and
new ones are filled up as soon as they are opened. Patients
turned away from treatment facilities typically return to
their communities, often on public transportation, likely
infecting several more people along the way. CDC
estimates that fatality rates could be halved if people were
able to access treatment and healthcare.24
Liberia faces the most severe treatment shortage. As of

to support the construction of 27 ETUs in the country, 12
of which will be built by the Department of Defense (DOD).25 Health experts are investigating a
recent reduction in people seeking Ebola care in Liberia, reportedly leaving some beds vacant.26
Safe disposal of dead bodies is also improving in Liberia, where roughly 90% of dead bodies are
being removed within 24 hours of being reported to the National Call Center.27 EVD responders
are also working with community leaders to adapt traditional funeral practices that can facilitate
EVD transmission, such as kissing and touching corpses.
The poor quality of health care delivery is also a concern. Inconsistent adherence to infection
control protocol, for example, is contributing to EVD cases among health workers. In July, CDC

U.S. and International Health Responses to the Ebola Outbreak in West Africa
investigated a cluster of Ebola cases among HCWs in Liberia and identified “multiple
opportunities for transmission of Ebola virus to HCWs, including exposure to patients with
undetected Ebola in the hospital, inadequate use of personal protective equipment during cleaning
and disinfection of environmental surfaces in the hospital, and potential transmission from an ill
HCW to another HCW.”28 During a September tour of Liberia, CDC Director Tom Frieden noted
inconsistent availability and use of gloves and hand washing. 29 Interruptions in water supply in
health clinics further hamper efforts to ensure necessary sanitation. Dr. Frieden noted of 29 health
centers surveyed during his tour to the affected region, only one had running water.30
The poor conditions of the health facilities also discourage attendance. Power outages and
interruptions in potable water delivery are common.31 In addition, ambulance services are
virtually non-existent in rural areas and limited in urban areas. One district in Sierra Leone with a
population of 465,000 people reportedly has only four ambulances, which are often overcrowded
with ill people, irrespective of Ebola infection status.32
Commodities/Supply Chain Networks
Shortages of protective gear are associated with EVD cases among health workers, and may
allow EVD to be spread within health facilities. The affected countries have limited supplies of
appropriate protective equipment and not all health and support personnel who interact with the
public have access to such equipment. Due to resource constraints, the protective equipment is
primarily provided to healthcare workers in Ebola treatment centers, leaving health workers who
operate among the general population at risk of contracting and spreading the disease (and other
infectious diseases) should they encounter an undiagnosed EVD case. WHO noted, however,
shortages of PPE even in ETUs.33 Health providers also lack sufficient supplies of antibiotics and
safe blood to treat Ebola. The price of disinfectants and medicine has reportedly doubled, as
people attempt to protect themselves and self-medicate in light of health system deficiencies.34
Transporting aid workers and commodities across and within the affected countries is
complicated by poor road conditions and the suspension of air service by several commercial
airlines. Efforts by the international community to develop alternative transportation routes have
improved the situation, though limited air service remains a problem.
Information
Awareness about preventing EVD infection has improved, but due to poverty, infrastructural
deficiencies (e.g., clean water and sanitation), and health system constraints, many people lack

means to avoid infection. Before Ebola hit, hunger was already a problem in the affected
countries, particularly in rural areas. Consumption of wild animals is common practice,
particularly in areas with high food insecurity. Health officials have been expanding efforts to
inform the public about the risks associated with eating wild animals, including fruit bats and
other animals that might carry EVD.35 Without sufficient access to food, hunger often compels
people to continue hunting and eating the animals despite the risks.

laboratory and surveillance systems. Health experts are
(as of October 22, 2014)
uncertain about how many EVD cases exist and where
they are occurring, particularly in Liberia where roughly
20% of EVD cases have been confirmed through
laboratory diagnosis (Figure 6). Limited laboratory
capacity has resulted in extensive diagnosis backlogs,
further calling into question the number of EVD cases and
hindering efforts to contain the outbreak. Uncertainty
about EVD cases endangers health workers, other patients,
and those living among people sickened by diseases of
undetermined origins.
International Health Responses
International responses are accelerating, though it remains
to be seen how much it will ultimately cost to contain the
outbreak and when this will be achieved. The financial
requirements for containing the outbreak are rising along
with the spread of the outbreak (Figure 7). In March,
WHO estimated that it would take $4.8 million to contain
the outbreak. At the end of April, more than 200 EVD
cases had been discovered in Guinea, less than a dozen in
Liberia, and none in Sierra Leone. In August, the
organization revised its Ebola response plan, estimating it

U.S. and International Health Responses to the Ebola Outbreak in West Africa
In September, the United Nations (U.N.) established the U.N. Mission for Ebola Emergency
Response (UNMEER) to coordinate the international response to the outbreak. That month, the
United Nations Security Council held a special meeting on Ebola, urging member states to
expedite support for the affected countries and to contribute to a U.N. integrated Ebola response
plan. The six-month, $988 million plan calls for addressing the health and social impacts of the
outbreak (Table 3).37 Roughly half of the funds would be spent on health programs and the
balance would be spent on addressing issues such as food insecurity, economic disruptions, and
establishing and maintaining supply chain networks.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
As of October 29, 2014, donors have contributed $493 million towards the UN plan and pledged
to provide an additional $279 million (Figure 8).38 Donors are also providing resources for
addressing the Ebola outbreak outside of the UN response. The United Nations Office for the
Coordination of Humanitarian Affairs (UNOCHA) estimates that some $894 million has been
committed for addressing the outbreak and an additional $938 million has been pledged for the
immediate and long-term preparedness needs. WHO and UNOCHA will likely revise their
requests for funding and material support as the outbreak continues to spread.

As indicated above, roughly half of the U.N. request for tackling the outbreak is aimed at
addressing direct health impacts. The World Health Organization is leading that component and
has outlined measures the international community would need to take to contain the outbreak by
January 2014. In the plan, entitled the Ebola Response Roadmap, WHO requested donors provide
roughly $490 million for:

U.S. and International Health Responses to the Ebola Outbreak in West Africa
WHO Community Care Campaign
Since September, pledges to send health workers to the region have increased, though human
resource constraints continue to inhibit containment efforts. Since September, several countries
have pledged medical support to the region, including Cuba’s commitment to deploy 165 health
professionals;39 a U.S. commitment to deploy 65 U.S. Public Health Service Commissioned
Corps officers for providing Ebola care in an DOD-established ETU;40 Britain’s provision of 750
troops, including medical officers;41 and China’s pledge to send more than 170 health workers.42
The African Union and East African Community have respectively committed to send 100 and
600 health workers.43
In light of human resource constraints, the Liberian Government, WHO, CDC, and other partners
developed the Community Care Campaign, which will initially be targeted at “the 400,000 most
vulnerable households in Liberia” and will be subsequently expanded to cover the rest of the
country and region.44 The Community Care Campaign calls for the establishment of community
care centers (CCCs), which will be managed and staffed by non-governmental organizations
(NGOs), community health workers (CHWs, lay people with rudimentary health training) and
family members of EVD patients. The CCCs are intended to “complement” Ebola Treatment
Units that are staffed by trained health practitioners and are operating at maximum capacity. The
Sierra Leonean government and implementing partners are also establishing CCCS in the country.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
U.S. Responses to Pandemic Threats and Ebola
The United States is the leading funder of the international Ebola response and its financial
support is continuing to rise. The U.S. Agency for International Development (USAID) reports
that as of October 22, U.S. humanitarian funding for EVD responses totaled $344.6 million.45 In
addition, the Department of Defense (DOD) is planning to spend more than $1 billion on
containing the outbreak in support of U.S. EVD activities in West Africa, as described below.46
On October 17, President Obama established an Ebola Czar to coordinate U.S. domestic and
global responses to the Ebola outbreak. The U.S. Global Ebola strategy has four key goals:
1) control the outbreak,
2) mitigate second order impacts,
3) establish coherent leadership and operations, and
4) advance global health security.
U.S. global efforts focus primarily on Liberia, where the outbreak is most widely spread, although
the United States is engaged in all three affected countries. As of October 25, nearly 900 U.S.
Government personnel are stationed in the region, more than 700 of which are among the 4,000
military personnel who will be deployed to the region.47
U.S. responses to the current Ebola outbreak are built on prior and ongoing efforts to build the
capacity of foreign nations to prepare and respond to disease outbreaks—including Ebola. These
activities are primarily implemented through USAID and CDC, though the U.S. Departments of
Agriculture, Defense, and State also contribute to such efforts. Pandemic preparedness programs
began in earnest after the 2005 avian flu outbreak and have experienced varying levels of
congressional support. The section below briefly describes U.S. pandemic preparedness efforts,
including Ebola outbreak responses, by agency.
USAID Pandemic Preparedness Efforts
Since 2005, USAID has invested roughly $1 billion on helping countries detect, prepare for, and
respond to outbreaks that originate in animals, such as Ebola, and that have the potential to cause
pandemics. 48 In FY2014, USAID spent $72.5 million on such efforts through the Emerging and
Pandemic Threats (EPT) program, which operates in 18 countries in Africa and Asia. The
program grew out of USAID’s initial response to H5N1 avian influenza in 2005.
Congress appropriates funds directly to USAID for EPT. These funds have fluctuated between
FY2005-FY2014 (Table 5). Related activities in 18 countries in East and Central Africa and
South and Southeast Asia focus on:

USAID Ebola Responses49
USAID has deployed a Disaster Assistance Response Team (DART) to West Africa to coordinate
the U.S. Government’s response to the Ebola outbreak. In coordination with other federal
agencies, the team is overseeing the U.S. response. Between March and October 2014, USAID
has committed to provide more than $300 million for combating Ebola in West Africa.50 This
included the provision of resources for 1,000 treatment beds, 130,000 sets of protective
equipment for healthcare staff and outbreak investigators, as well as 50,000 hygiene kits, which
include soap, bleach, gloves, masks, and other supplies to help prevent the spread of disease.51
USAID is also supporting the International Federation of Red Cross and Red Crescent Societies
(IFRC) to raise public awareness of Ebola’s mode of transmission, teach disease prevention
practices to communities, train volunteers to detect Ebola symptoms and identify contacts of
confirmed or suspected cases for further monitoring, and support safe burial and body
management activities. USAID has reprogrammed funds from the Global Heath and International
Disaster Assistance accounts to fund these efforts.

CDC funds its global pandemic preparedness efforts through a variety of accounts, including the
Global Disease Detection (GDD) program, Emerging and Zoonotic Infectious Diseases, Global
Health, Immunization and Respiratory Diseases, and Public Health Preparedness and Response.
The Centers leverage resources from these and other program accounts to respond to global
disease outbreaks—including Ebola. Appropriations for GDD have grown since 2003 (Table 6).

CDC has requested additional support ($45 million) in FY2015 to fund activities in support of the
Global Health Security Agenda, which will accelerate activities to detect, prevent, and respond to
global infectious disease threats like Ebola.52 CDC directly or indirectly supports pandemic
influenza preparedness efforts in more than 50 countries. In some cases, CDC sends experts to
work with WHO country offices or foreign health ministries, and at other times, CDC forms
cooperative agreements with partners to support country efforts.
CDC Ebola Responses53
At the end of March 2014, CDC teams traveled to Guinea and Liberia to help those Health
Ministries characterize and control the outbreak, identify and manage EVD cases, conduct contact
tracing, and improve data management. Following an initial response, new cases flared up after
appearing to decelerate for some time. CDC returned to the region and began resumed technical
assistance efforts. In addition to the activities discussed above, CDC is also training airport
personnel and working with partners to display Ebola-specific travel messages for electronic
monitors and posters at airports in the affected countries. CDC is not providing direct care of
Ebola patients. As of October 22, 2014, CDC has committed more than $16.7 million for its
Ebola responses.54
Department of Defense Ebola Responses
Until recently, DOD responses to the outbreak were focused on researching treatments and
vaccines and providing laboratory diagnostic assistance to Sierra Leone and Liberia. On
September 8, DOD announced that it would provide $22 million to set up a 25-bed field hospital

in Liberia that would be used to treat EVD cases among healthcare workers. The Department of
Health and Human Services (HHS) U.S. Public Health Service Commissioned Corps will deploy
65 officers “to Liberia to manage and staff the hospital.”55 Military personnel will establish and
supply the facility, but not provide direct medical care.56
On September 16, President Barack Obama announced the launch of “Operation United
Assistance.”57 The operation is to be based in Monrovia, Liberia, will entail the deployment of
roughly 4,000 U.S. military forces, and be overseen and coordinated by the DOD U.S. Africa
Command. The operation will support:
•
the coordination of U.S. and international relief efforts;
•
the provision of medical personnel to train up to 200 health workers weekly; and
•
the establishment of 12 treatment centers in Liberia, each with 100-bed capacity.
Operation-related efforts are underway. The first 22-bed ETC is expected to be completed by the
end of October and three others are to be completed in November.58 More than 700 U.S. military
personnel are in the region, including personnel from the U.S. Naval Medical Research Center
who are operating three mobile medical labs for EVD testing.59 Congress has approved several
DOD reprogramming requests to fund Operation United Assistance as well as other related
activities, including those that supply personal protective equipment, laboratory inputs, and
technical advisors to the region. Total DOD funding for the global Ebola response is expected to
exceed $1 billion.60
Possible Issues for Congress
The current Ebola outbreak has overwhelmed the governments of Guinea, Sierra Leone, and
Liberia. Insufficient capacity to detect, treat, and prevent the spread of disease has enabled the
virus to spread and has further weakened health systems that were already inundated and in
dilapidated conditions. Congress has held several hearings on the outbreak and enacted legislation
that urged expanding U.S. and international responses and that provided funds for U.S. responses.
As the outbreak continues to spread, the Administration may request additional funds to contain
the outbreak. This section describes issues Congress may consider as it assesses U.S. and
international responses.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Human Resource Constraints
At the end of August, WHO estimated that it would take 13,000 health workers to contain the
Ebola outbreak.61 Although foreign governments and non-governmental organizations are
beginning to deploy medics and other health workers, their numbers are not sufficient to meet the
human resource demands. Human resource constraints are most acute in Liberia, where access to
Ebola care is the most limited. The United States has partnered with the Liberian government,
WHO, and other groups to develop a Community Care Campaign (see “WHO Community Care
Campaign”). Doctors Without Borders (known by its French acronym, MSF) has expressed
concern about the Community Care Campaign, asserting that the CCCs could turn into
“contamination centers” without strict infection control, adequate supplies, trained staff, regular
supervision, the ability to diagnose and refer patients, and proper burial methods.62 WHO
acknowledges that “any deficiencies in the quality of implementation could present major risk of
virus transmission within the CCC thus exacerbating a situation it is set out to address.”63 Key
factors that may complicate safe implementation of the Community Care Campaign include:
•
Quality control. Inconsistent adherence to infection control protocol is
reportedly contributing to EVD cases among health workers. The inability to
ensure disease infection, prevention, and control (IPC) protocols among trained
health personnel calls into question whether non-governmental organizations,
community health workers, and family members will adhere to IPC protocols.
This concern is particularly acute for lay personnel (like family members) who
may provide Ebola care in the CCCs.
•
Family care providers. To avoid the possible spread of EVD from familial
caretakers to other community members, WHO recommends that only one family
member provide care for each patient for the duration of their stay in the CCCs.
WHO specifies that the “family member providing supportive care to the patient
must not go back and forth between the CCC and the community.”64 However,
collective familial care of and close community interaction with the ill is
common in Liberia. It is unclear whether CCC supervisors will be able to curtail
this custom and ensure that only one family member provides care. Other factors,
including loss of income, separation of the caretaker from their uninfected family
members, or emotional stress from being in a CCC, might also discourage
compliance with WHO familial care guidelines.
•
Waste management and safe burial practices. IPC protocol requires that those
handling the soiled linen of EVD patients, cleaning the CCCs, or burying victims
of EVD wear personal protective equipment (PPE). Further, in order to prevent
the spread of EVD within CCCs, caretakers must follow strict protocol in using
PPE and managing waste (using only designated areas for waste disposal and
ensuring daily collection of human and PPE waste). The affected countries face
deficiencies in waste management. In 2012, less than 20% of people living in the

affected countries had access to improved sanitation facilities.65 It may be a
challenge ensuring strict adherence to IPC protocol among lay care takers
without medical training, particularly if they lack access to sanitation themselves.
•
Oversight. According to WHO, “monitoring and supervision is critical in
ensuring the success of the approach.”66 Most of the “low level community health
workers and members of the community” who will be tasked with providing care
in CCCs have never done so before. The Community Care Campaign calls for
once daily supervisory visits by at least one health care worker trained in IPC. It
remains to be seen whether once daily visits are enough to ensure compliance
with the IPC protocols, as well as others, including proper and consistent use of
PPE by care takers, launderers, burial team, and sanitation workers.
•
Supply chain management. Due to poor supply chain management practices,
many publicly funded health clinics in the affected countries face interruptions in
medical supplies and often lack commodities such as gloves, masks, and gowns.
A lack of protective equipment in ETUs and health clinics has been associated
with EVD infection among health workers.67 Lapses in protective gear in CCCs
can lead to unsafe practices, such as recycling or reusing existing PPE. It remains
to be seen whether WHO and its partners will be able to ensure the continuous
supply of commodities to disparate CCCs.
WHO recognizes the inherent risks of this effort and advises that Ministries of Health in the
affected countries “embark on this approach in an incremental manner starting with a few pilots
that are well monitored before taking it up to scale.”68
U.S. implementation of the Community Care Campaign is already underway. USAID is issuing
grants to non-governmental organizations to oversee the management of Community Care
Centers. The White House reports that the United States Government has already provided 9,000
community care kits in Liberia for use by individuals in their homes.69 NGOs generally have
autonomy over the implementation of USAID grants, and USAID oversees implementation to
ensure that program targets are met. Questions abound, however, about U.S. oversight and
implementation of this campaign, particularly regarding U.S. government oversight of grantees
managing CCCs and the standardization of quality control and IPC protocol.
Leadership of the International Outbreak Response
Observers have criticized WHO leadership over the global Ebola response. Some critics have
contended that budget cuts that began under WHO’s reform efforts have made the Organization
less effective and have limited its capacity to contain the outbreak.70 The 2014-2015 WHO
program budget called for a 51% reduction in outbreak and crisis response activities from 201265

2013 levels.71 Some observers maintain that earlier budget cuts have also crippled the agency by
reducing critical staff, causing the closure of the viral hemorrhagic fever unit, and undermining
operational capacity.72 Beyond budgetary constraints, some critics contended that WHO’s
response has been stymied by bureaucratic bloat and undue influence of underqualified staff who
attained their positions due to political relationships.73
Weak health systems in the affected countries, inadequate capacity of WHO to carry out its own
Ebola plans, as well as insufficient international responses to the outbreak have reignited debates
about whether WHO should function primarily as an advisory body or maintain some form of
operational capacity. Some analysts advocate for the establishment of a WHO-administered
“Health Systems Fund,” that could be used to both build long-term health system capacity, as
well as address short-term crises like the ongoing Ebola outbreak.74 While supporting the need for
a ready-to-deploy team of emergency health responders, others assert the “politics of
sovereignty” would preclude WHO from leading such an effort.75
U.S. Support for Ebola Responses and Health Systems
The speed at which EVD is spreading across West Africa is attributable, in large part, to weak
health systems in those countries. Donors have long grappled with how to address health
emergencies in light of dysfunctional health systems. In the early 2000s, donors turned to diseasebased funding and channeled health aid through non-governmental groups. Opponents of this
approach argued that disease-specific programs exacerbate human resource shortages in the
public sector and further weaken health systems when parallel bureaucracies are established and
government authorities are bypassed. Supporters assert that disease-based funding strengthens
oversight capacity and facilitates the monitoring and evaluation of the investments.
This debate intensified following the introduction of the President’s Emergency Plan for AIDS
Relief (PEPFAR).76 In an effort to curb the massive number of deaths that followed the
introduction of HIV/AIDS, U.S. agencies provided funding to large non-governmental
organizations and local partners who established care and treatment facilities outside of
government networks. While the effort helped save millions of lives and averted millions more
HIV infections, the United States became the sole supporter for millions of people worldwide
whose lives would be at risk should U.S. funding be discontinued. In the second phase of
PEPFAR (FY2009-FY2013), increasing portions of PEPFAR resources were used to support

U.S. and International Health Responses to the Ebola Outbreak in West Africa
health systems in hopes of bolstering country capacity to assume ownership over HIV/AIDS
programs. Now in its third phase, debate on the use of PEPFAR funds for building health systems
has resumed. A 2013 GAO report noted that roughly 21% of PEPFAR funds were spent on
capacity building projects under the “other” budgetary category. At her confirmation hearing,
PEPFAR Country Coordinator Deborah Birx asserted that under her leadership, 50% of all
PEPFAR resources, including those funded through other accounts, would be spent on care and
treatment activities, as mandated. Health system advocates fear that budgetary reforms aimed at
adhering to the law may imperil efforts to bolster health systems.
The U.S. Congress faces a similar dilemma with the current Ebola outbreak. The affected
countries need focused support to contain and end this outbreak. If and when the outbreak is
arrested, however, the countries may not be in any better position to detect, prevent, or respond to
other potential disease outbreaks unless donors begin the arduous task of supporting the
development of strong health systems. Ken Isaacs, Vice President of International Programs and
Government Relations at Samaritan’s Purse, described this dilemma at an August 2014
congressional hearing on Ebola, stating “While it should be the goal of the developed world to
build capacity, the building of this capacity should not be the focus during times of an emergency
crisis of a deadly disease that threatens the international community.”77 USAID has reportedly
established an Ebola Health Systems Strengthening working group to support the resumption of
health care delivery and to bolster the health systems once the outbreak is contained.78
Though PEPFAR and other U.S.-funded health programs have attempted to respond to calls for
greater investment in health systems, no appropriations specifically targeting such efforts are
provided. Language in appropriations and accompanying conference reports direct the majority of
health aid to particular diseases, leaving minimal resources for broader activities to strengthen
health systems. The inability of the affected countries to respond to an unforeseen health event
may prompt Congress to review how global health funds are appropriated.
Evaluating U.S. Responses
A variety of U.S. agencies are responding to the ongoing Ebola outbreak. The Department of
State is leading diplomatic engagements; USAID is coordinating U.S. responses, including the
provision of financial and material support; CDC is heading public health and medical response
activities; and DOD is handling support for foreign armed forces. With the exception of USAID,
the budgetary structure of each of these agencies enables them to respond to this unanticipated
event by drawing from accounts that have flexible authorities. The Department of State’s efforts
to coordinate bilateral diplomatic engagements are conducted through existing channels (e.g.,
embassy contacts) and, as such, would not require additional, dedicated funding. Outbreak
responses by the CDC can be financed through USAID disaster assistance accounts, as well as
several CDC accounts that are used for domestic and international health efforts and for which
there is not explicit congressional direction on their use. The DOD budget also supports an array
of domestic and international health activities that do not receive detailed congressional direction.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Congress has established numerous directives over the years on how foreign aid funds are to be
used. As the lead U.S. development agency, USAID often receives specific direction from
Congress on how the bulk of its funds will be used through annual appropriations, leaving the
agency with limited ability to address unanticipated events, like the current Ebola outbreak,
without drawing from ongoing health efforts. According to USAID, it is currently reprogramming
funds planned for preventing future outbreaks, as well as addressing ongoing outbreaks
(including responses to H7N9 avian influenza in China and MERS-CoV in the Middle East), to
address the current Ebola outbreak.79
Supporters of the current appropriation structure see it as a tool for overseeing health programs
and ensuring that congressional priorities are met. Opponents argue that congressional directives
encumber the agility that is needed in the field and create artificial segmentation of health and
development issues, thereby limiting the impact and sustainability of such efforts.
By their nature, disease outbreaks are often unpredictable, though with appropriate disease
surveillance, detection, and response mechanisms, their impact can be minimized. At present,
USAID pandemic preparedness efforts are focused on East and Central Africa, where previous
Ebola and influenza outbreaks have occurred, as well as South and Southeast Asia. Now that
Ebola has emerged in West Africa, another EVD outbreak may occur in the region; a scenario the
affected countries may be ill-prepared to handle. The FY2015 budget request ($50 million) for
pandemic preparedness is roughly 30% less than the FY2014 funding level ($73 million). Even if
Congress funds USAID pandemic preparedness programs at the FY2014 funding level, one
USAID official contends that it will not be enough to meet current demands.80
Addressing the Long-Term and Broader Effects of the Outbreak
Under the best of circumstances, experts predict that the outbreak can be contained by the end of
January. In the meantime, the high death tolls are disrupting social structures and may cause
broad, long-term effects in the region. MSF has reported that some affected villages in Sierra
Leone have lost the majority of adult community members, leaving vulnerable populations—such
as children and the elderly—without resources to cultivate agricultural land and procure food.81
Observers are also concerned about a growing number of children who are being orphaned from
Ebola. This group is particularly vulnerable to marginalization due to overwhelming fear of the
virus. Countries in West and Central Africa already had large orphan populations due to a variety
of causes including armed conflict and HIV/AIDS. In 2012, some 28 million children were
orphaned in the region, of whom more than 4 million lost one or more parent to AIDS.82 The
outbreak is also hindering the capacity of these governments to address other health issues, such
as obstetrical complications. Experts are concerned that child and maternal mortality rates,
already high in the region, may further rise due to diminishing numbers of health personnel
(caused both by Ebola deaths and abandonment of posts), diversion of limited resources to Ebola
treatment centers, and public avoidance of health centers.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
The full health effects of the Ebola outbreak may not be known until it is contained. An
accounting of broader health and development needs will likely ensue and may rekindle debate
over how U.S. global health assistance funds are apportioned. Congress is likely to face
arguments from advocates from a variety of actors attempting to garner support for a bevy of
health and development issues that will have likely worsened in the wake of Ebola, including
maternal and child mortality, child vulnerability and orphanhood, poverty, food scarcity, and
water-borne infections.
Considering Research and Development Needs
Since 1976, several Ebola outbreaks have erupted in sub-Saharan Africa, yet therapeutic options
remain undeveloped. There is no specific cure, treatment, or vaccine for Ebola, nor or is there any
post-exposure prophylaxis for health workers who face regular exposure. Treatment of EVD
symptoms increases the probability of survival. Several experimental specific treatments and
vaccines are beginning clinical trials to determine their safety and efficacy. The appropriate use of
experimental drugs that have not been tested for human safety and effectiveness has become a
matter of debate, particularly around the issue of equity.
A global health lawyer described the ensuing debate. “Should [U.S.] workers receive a drug in
extremely scarce supply when Africans are affected in far greater numbers? Balanced against this
sense of injustice is the ethical concern of administering an experimental drug to African patients
that has not undergone any safety testing in humans.”83 In addition, if the experimental drugs are
ineffectual or cause serious side effects, then their use may further exacerbate mistrust in
healthcare workers and modern medical treatments. WHO held a special meeting in August on
the topic and announced that under “the particular circumstances of th[e] outbreak, and provided
certain conditions are met ... it is ethical to offer unproven interventions with as yet unknown
efficacy and adverse effects, as potential treatment or prevention.”84
In October, press reports indicated that WHO planned to begin testing two Ebola vaccines in
January on some 20,000 health workers and other volunteers. The organization also indicated that
a limited amount of an experimental treatment might be available for use in Liberia by early
November.85 At the end of October, WHO convened a meeting “with high-ranking government
representatives from Ebola-affected countries and development partners, civil society, regulatory
agencies, vaccine manufacturers and funding agencies yesterday to discuss and agree on how to
fast track testing and deployment of vaccines in sufficient numbers to impact the Ebola
epidemic.”86 Once the trials commence, debates about ethical practices will likely ensue,
particularly if trial participants die or experience other adverse reactions.

U.S. and International Health Responses to the Ebola Outbreak in West Africa
Conclusion
In an August 29, 2014 report, WHO warned that bordering countries, namely Benin, Burkina
Faso, Côte d’Ivoire, Guinea-Bissau, Mali, and Senegal, were “at risk” of seeing Ebola cases.87 On
October 23, 2014, Mali reported its first Ebola case and health officials suspect that cases may
exist in other neighboring countries. WHO is reportedly helping neighboring countries to build
EVD surveillance, preparedness and response plans. An Oxford University study concluded that
some 22 million people across Central and West Africa live in forested areas where one of the
suspected vectors (fruit bats) resides,88 raising concerns among some that future Ebola outbreaks
may occur in the region and other parts of sub-Saharan Africa. The article notes that “changes in
human mobility and connectivity will likely have profound impacts on the dispersion of Ebola cases.”
Prospects for future Ebola outbreaks in urban areas and in countries with limited pandemic
preparedness capacity raise several questions, including:
•
Is the U.S. response to the Ebola outbreak effective?
•
Does the United Stated sufficiently support pandemic preparedness efforts?
•
Does disease-specific funding encumber pandemic preparedness efforts?
•
Will the reprogramming of USAID funds to address the Ebola outbreak impact
ongoing global health and development programs?
•
Are ongoing outbreak responses by the U.S. and international improving the
capacity of the affected countries, as well as others in the region, to identify,
detect, and respond to future outbreaks?
