Approaches to Vaccination Among Populations in Areas of Conflict.

Vaccination is an important and cost-effective disease prevention and control strategy. Despite progress in vaccine development and immunization delivery systems worldwide, populations in areas of conflict (hereafter, "conflict settings") often have limited or no access to lifesaving vaccines, leaving them at increased risk for morbidity and mortality related to vaccine-preventable disease. Without developing and refining approaches to reach and vaccinate children and other vulnerable populations in conflict settings, outbreaks of vaccine-preventable disease in these settings may persist and spread across subnational and international borders. Understanding and refining current approaches to vaccinating populations in conflict and humanitarian emergency settings may save lives. Despite major setbacks, the Global Polio Eradication Initiative has made substantial progress in vaccinating millions of children worldwide, including those living in communities affected by conflicts and other humanitarian emergencies. In this article, we examine key strategic and operational tactics that have led to increased polio vaccination coverage among populations living in diverse conflict settings, including Nigeria, Somalia, and Pakistan, and how these could be applied to reach and vaccinate populations in other settings across the world.

Containment of Ebola and Polio in Low-Resource Settings Using Principles and Practices of Emergency Operations Centers in Public Health.

Emergency Operations Centers (EOCs) have been credited with driving the recent successes achieved in the Nigeria polio eradication program. EOC concept was also applied to the Ebola virus disease outbreak and is applicable to a range of other public health emergencies. This article outlines the structure and functionality of a typical EOC in addressing public health emergencies in low-resource settings. It ascribes the successful polio and Ebola responses in Nigeria to several factors including political commitment, population willingness to engage, accountability, and operational and strategic changes made by the effective use of an EOC and Incident Management System. In countries such as Nigeria where the central or federal government does not directly hold states accountable, the EOC provides a means to improve performance and use data to hold health workers accountable by using innovative technologies such as geographic position systems, dashboards, and scorecards.

Rapid response to Ebola outbreaks in remote areas - Liberia, July-November 2014.

West Africa is experiencing its first epidemic of Ebola virus disease (Ebola). As of February 9, Liberia has reported 8,864 Ebola cases, of which 3,147 were laboratory-confirmed. Beginning in August 2014, the Liberia Ministry of Health and Social Welfare (MOHSW), supported by CDC, the World Health Organization (WHO), and others, began systematically investigating and responding to Ebola outbreaks in remote areas. Because many of these areas lacked mobile telephone service, easy road access, and basic infrastructure, flexible and targeted interventions often were required. Development of a national strategy for the Rapid Isolation and Treatment of Ebola (RITE) began in early October. The strategy focuses on enhancing capacity of county health teams (CHT) to investigate outbreaks in remote areas and lead tailored responses through effective and efficient coordination of technical and operational assistance from the MOHSW central level and international partners. To measure improvements in response indicators and outcomes over time, data from investigations of 12 of 15 outbreaks in remote areas with illness onset dates of index cases during July 16-November 20, 2014, were analyzed. The times to initial outbreak alerts and durations of the outbreaks declined over that period while the proportions of patients who were isolated and treated increased. At the same time, the case-fatality rate in each outbreak declined. Implementation of strategies, such as RITE, to rapidly respond to rural outbreaks of Ebola through coordinated and tailored responses can successfully reduce transmission and improve outcomes.

Outreach to underserved communities in northern Nigeria, 2012-2013.

BACKGROUND: Persistent wild poliovirus transmission in Nigeria constitutes a major obstacle to global polio eradication. In August 2012, the Nigerian national polio program implemented a strategy to conduct outreach to underserved communities within the context of the country's polio emergency action plans. METHODS: A standard operating procedure (SOP) for outreach to underserved communities was developed and included in the national guidelines for management of supplemental immunization activities (SIAs). The SOP included the following key elements: (1) community engagement meetings, (2) training of field teams, (3) field work, and (4) acute flaccid paralysis surveillance. RESULTS: Of the 46,437 settlements visited and enumerated during the outreach activities, 8607 (19%) reported that vaccination teams did not visit their settlements during prior SIAs, and 5112 (11.0%) reported never having been visited by polio vaccination teams. Fifty-two percent of enumerated settlements (23,944) were not found in the existing microplan used for the immediate past SIAs. CONCLUSIONS: During a year of outreach to >45,000 scattered, nomadic, and border settlements, approximately 1 in 5 identified were missed in the immediately preceding SIAs. These missed settlements housed a large number of previously unvaccinated children and potentially served as reservoirs for persistent wild poliovirus transmission in Nigeria.

Establishment of a community care center for isolation and management of Ebola patients - Bomi County, Liberia, October 2014.

As of October 29, 2014, a total of 6,454 Ebola virus disease (Ebola) cases had been reported in Liberia by the Liberian Ministry of Health and Social Welfare, with 2,609 deaths. Although the national strategy for combating the ongoing Ebola epidemic calls for construction of Ebola treatment units (ETUs) in all 15 counties of Liberia, only a limited number are operational, and most of these are within Montserrado County. ETUs are intended to improve medical care delivery to persons whose illnesses meet Ebola case definitions, while also allowing for the safe isolation of patients to break chains of transmission in the community. Until additional ETUs are constructed, the Ministry of Health and Social Welfare is supporting development of community care centers (CCCs) for isolation of patients who are awaiting Ebola diagnostic test results and for provision of basic care (e.g., oral rehydration salts solutions) to patients confirmed to have Ebola who are awaiting transfer to ETUs. CCCs often have less bed capacity than ETUs and are frequently placed in areas not served by ETUs; if built rapidly enough and in sufficient quantity, CCCs will allow Ebola-related health measures to reach a larger proportion of the population. Staffing requirements for CCCs are frequently lower than for ETUs because CCCs are often designed such that basic patient needs such as food are provided for by friends and family of patients rather than by CCC staff. (It is customary in Liberia for friends and family to provide food for hospitalized patients.) Creation of CCCs in Liberia has been led by county health officials and nongovernmental organizations, and this local, community-based approach is intended to destigmatize Ebola, to encourage persons with illness to seek care rather than remain at home, and to facilitate contact tracing of exposed family members. This report describes one Liberian county's approach to establishing a CCC.

Ebola epidemic--Liberia, March-October 2014.

On March 21, 2014, the Guinea Ministry of Health reported the outbreak of an illness characterized by fever, severe diarrhea, vomiting and a high fatality rate (59%), leading to the first known epidemic of Ebola virus disease (Ebola) in West Africa and the largest and longest Ebola epidemic in history. As of November 2, Liberia had reported the largest number of cases (6,525) and deaths (2,697) among the three affected countries of West Africa with ongoing transmission (Guinea, Liberia, and Sierra Leone). The response strategy in Liberia has included management of the epidemic through an incident management system (IMS) in which the activities of all partners are coordinated. Within the IMS, key strategies for epidemic control include surveillance, case investigation, laboratory confirmation, contact tracing, safe transportation of persons with suspected Ebola, isolation, infection control within the health care system, community engagement, and safe burial. This report provides a brief overview of the progression of the epidemic in Liberia and summarizes the interventions implemented.

Evolution of infection control in Egypt: achievements and challenges.

BACKGROUND: The high prevalence of hepatitis C virus (HCV) infection in Egypt highlighted the urgent need for implementing infection control (IC) programs in Egypt. OBJECTIVES: The Ministry of Health and Population (MOHP), in collaboration with the US Naval Medical Research Unit No. 3, and the World Health Organization (WHO), developed a national plan to initiate an IC program with the objectives of improving quality of care and reducing transmission of hospital-acquired infections. METHODS: The strategic plan for this program included setting up an organizational structure, developing IC national guidelines, training health care workers, promoting occupational safety, and establishing a system for monitoring and evaluation. Implementation of the program started in late 2001. RESULTS: The achievements to date include developing a national organizational structure, IC guidelines, and a comprehensive IC training program. To date, a total of 72 hospitals in 13 governorates have been enrolled in the program, and 235 IC professionals have been trained. CONCLUSIONS: Many challenges were faced, including administrative, financial, and motivational difficulties. Future plans include expansion of the program to cover all 27 governorates of Egypt and establishment of a surveillance system for hospital-acquired infections. The process of developing the IC program in Egypt may serve as a model for other resource-limited countries that seek to initiate similar programs.

CDC's Response to the 2014-2016 Ebola Epidemic - Guinea, Liberia, and Sierra Leone.

CDC's response to the 2014-2016 Ebola virus disease (Ebola) epidemic in West Africa was the largest in the agency's history and occurred in a geographic area where CDC had little operational presence. Approximately 1,450 CDC responders were deployed to Guinea, Liberia, and Sierra Leone since the start of the response in July 2014 to the end of the response at the end of March 2016, including 455 persons with repeat deployments. The responses undertaken in each country shared some similarities but also required unique strategies specific to individual country needs. The size and duration of the response challenged CDC in several ways, particularly with regard to staffing. The lessons learned from this epidemic will strengthen CDC's ability to respond to future public health emergencies. These lessons include the importance of ongoing partnerships with ministries of health in resource-limited countries and regions, a cadre of trained CDC staff who are ready to be deployed, and development of ongoing working relationships with U.S. government agencies and other multilateral and nongovernment organizations that deploy for international public health emergencies. CDC's establishment of a Global Rapid Response Team in June 2015 is anticipated to meet some of these challenges. The activities summarized in this report would not have been possible without collaboration with many U.S. and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html).
