Measles Elimination in the WHO African Region: Progress and Challenges

In 2001; countries in the African Region adopted the measles mortality reduction strategies recommended by the WHO and UNICEF. Following the significant reduction in measles cases and deaths with the implementation of the strategies; in 2011; the African Region adopted a measles elimination goal for 2020. To assess progress; performance was reviewed using estimates of the first dose of measles vaccine in routine immunization (MCV1); the reported coverage for measles supplementary immunization activities (SIAs); as well as surveillance data. During 2011-2013; regional MCV1 coverage was stagnant at around 74; while approximately 215 million children were reached in measles SIAs in 43 countries. Regional measles vaccination coverage has not increased and measles incidence has remained high in the past three years. Intensive efforts are required to ensure that routine immunization and SIAs provide high population immunity; and to increase the sensitivity of measles surveillance

Overview of the WHO Polio Laboratory Network in the African Region

The Polio Laboratory Network has always played a critical role in diagnosing poliovirus disease (poliomyelitis) and the detection of poliovirus transmission. In the new millennium; the strength of the laboratory network is often a direct reflection of the success of the Polio Eradication Initiative (PEI) programme. The network has taken advantage of new technologies that provide speedy turnaround times for results reporting thus contributing to the success of the PEI programme. This article presents a brief overview of the work of the network

Laboratory Capacity in 2012 for Diagnosis of Epidemic Prone Diseases in the Context of Integrated Disease Surveillance and Response in the WHO African Region

This paper provides the status of laboratory capacity for diagnosis of epidemic prone diseases in the context of Integrated Disease Surveillance and Response (IDSR) in 46 countries in the WHO African Region as of end of 2012 through self-assessment questionnaires. The findings from this assessment revealed that 98 (45/46) of the countries have the capacity for isolation; identification and antimicrobial susceptibility testing of common bacterial causes of enteric diseases and meningitis in the Region. Forty three countries performed standard enzyme-linked immunosorbent assay (ELISA) for confirming suspected cases of pathogens such as Morbillivirus responsible of measles through the detection of specific immunoglobulin M (IgM) and 30 countries had at least polymerase chain reaction (PCR) capacity for detection of influenza viruses. However; the number of countries with an appropriate department of virology providing comprehensive diagnostic services is still limited especially for dangerous viral pathogens requiring high-level containment facilities. The collection and analysis of critical information on the existing diagnostic capacity were used to propose key recommendations for strengthening the laboratory confirmation of outbreaks in line with the IDSR Strategy and the International Health Regulations (IHR; 2005). The proposed key actions were focused in the following areas: high-level advocacy for country ownership; human resource development; laboratory space and equipment; quality assurance and laboratory networking
