Spatial-temporal distribution of chikungunya virus in Brazil: a review on the circulating viral genotypes and Aedes ( Stegomyia ) albopictus as a potential vector

Chikungunya virus (CHIKV) is mainly transmitted by the invasive mosquito ( ) in tropical and subtropical regions worldwide. However, genetic adaptations of the virus to the peri domestic mosquito vector ( ) has resulted in enhanced vector competence and associated epidemics and may contribute to fur...

Description
Summary:Chikungunya virus (CHIKV) is mainly transmitted by the invasive mosquito ( ) in tropical and subtropical regions worldwide. However, genetic adaptations of the virus to the peri domestic mosquito vector ( ) has resulted in enhanced vector competence and associated epidemics and may contribute to further geographic expansion of CHIKV. However, evidence-based data on the relative role of in CHIKV transmission dynamics are scarce, especially in regions where is the main vector, such as in Brazil. Here, we review the CHIKV genotypes circulating in Brazil, spatial and temporal distribution of Chikungunya cases in Brazil, and susceptibility to infection and transmission (i.e., vector competence) of for CHIKV to better understand its relative contribution to the virus transmission dynamics.
