Abstract
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.
Keywords:
Brazil; ECSA genotype; East/Central/South African genotype; Maceió; Zika virus; chikungunya virus; dengue virus; genetic epidemiology; vector-borne infections; viruses.
