Laboratory capacity in 2012 for diagnosis of epidemic prone diseases in the context of Integrated Disease Surveillance and Response in the WHO African Region

摘要

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.
