Abstract
Measles is a respiratory disease caused by the measles virus (MV) belonging to the Paramyxovirus family and the Morbillivirus genus. Due to a failure in maintaining immunization coverage in some countries, measles is a re-emerging disease in the human population, especially in Africa. The aim of this study was to describe a measles epidemic in Gabon. At first, a syndromic surveillance was set up. Blood samples from febrile patients with maculopapular rash were taken and sent to the measles reference center in Cameroon for laboratory confirmation. Between March and May 2016, 79 clinically suspected cases were reported including 82.3% (n=65) and 17.7% (n=14) in Oyem and Libreville, respectively. In total, 39.2% (n=31) of children were 11 months-old, 34.2% (n=27) were children aged 1 to 4 years, 11.4% (n=9) were older children from 5 to 9 years, 6.3% (n=5) of children were aged 10 to 15 years and 8.9% (n=7) were 15 years and older. 53.3% (16/30) were laboratory confirmed. This measles outbreak reiterates the importance of maintaining a high level of vaccine coverage in Gabon for vaccine-preventable diseases, as well as the usefulness of a near-real-time surveillance system for the detection of infectious diseases.
Highlights
Article collected in patients who came to the hospital centers for a consultation and were suspected to be infected by the measles virus
Confirmation of measles cases In response to the increase in reported measles cases, active surveillance for measles was initiated in both provinces, using the World Health Organization (WHO) case definition.[6]
Concurrent infections with the chikungunya and dengue viruses occurred during simultaneous epidemics in Gabon in 2007.8-12 These epidemics, which are not included in the WHO data, are described for the most part in various scientific publications
Summary
Measles can this study was to assess the effectiveness of disease in the human population, especially induce several complications such as ear a syndromic surveillance system able of in Africa. These hospitals participate in the syndromic surveillance network for infectious diseases with epidemic potential (SuSyMIPE).
