First Chikungunya-infected Aedes aegypti mosquitoes found in Brazil

While more than 13,000 cases of Chikungunya viral disease were reported in Brazil in 2015, scientists had never before detected the virus in a captured mosquito in this country. Now, researchers have identified a mosquito -- caught in the Brazilian city of Aracaju -- that's naturally infected with the East-Central-South-African (ECSA) genotype of Chikungunya.
