Molecular Characterization of Measles Viruses in Central African Republic, 2012-2016

Article scientifique 2022 Anglais

Résumé

Abstract Despite being preventable through vaccination, measles is still one of the most important causes of morbidity and mortality in young children in Africa. In 2015, several African countries, including the Central African Republic, began implementing national measles elimination programs. However, measles remains a public health problem in Africa, particularly in the Central African Republic. A retrospective study was conducted at the Institut Pasteur de Bangui, using blood samples (n = 255) and oral swabs (n = 7) collected between January 2012 and December 2016 from measles IgM positive cases to attempt genotyping of circulating measles virus strains. Overall, 50 samples were positive by RT-PCR, and 40 sequences of acceptable quality were obtained. The phylogenetic analysis showed that 38 strains belonged to genotype B3 suggesting that the genotype B3 was endemic in the CAR during the study period. No genotype B2 sequences were detected, suggesting that this genotype is no longer present in the CAR.
