Entomologic investigation reveals Aedes furcifer as the primary chikungunya vector, suggesting revised control strategies.

Chikungunya virus was detected primarily in Aedes furcifer, highlighting its role over Aedes aegypti.
Out of 31 positive mosquito pools, 22 were from Aedes furcifer and only 1 from Aedes aegypti.
