Spread of Chikungunya Virus East/Central/South African Genotype in Northeast Brazil.

Emerg Infect Dis; 23(10): 1742-1744, 2017 10.
Article in English | MEDLINE | ID: mdl-28930031
We investigated an outbreak of exanthematous illness in Maceió by using molecular surveillance; 76% of samples tested positive for chikungunya virus. Genetic analysis of 23 newly generated genomes identified the East/Central/South African genotype, suggesting that this lineage has persisted since mid-2014 in Brazil and may spread in the Americas and beyond.
