What are the primary mosquito vectors for transmitting Dengue?

The primary mosquito vectors responsible for transmitting Dengue fever are Aedes aegypti and Aedes albopictus. These two species are particularly adept at spreading the virus, as they thrive in urban environments where they come into close contact with human populations. Aedes aegypti, in particular, is well-known for its distinct white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax, making it easily identifiable.

These mosquitoes are day biters, which further increases the likelihood of transmission during daytime activities when people are more active. They also breed in standing water typically found in man-made containers, which makes controlling their populations challenging in urban settings. Understanding the role of Aedes mosquitoes in the transmission of Dengue helps in developing targeted public health strategies and effective mosquito control programs.

Other mosquito species listed, such as Anopheles and Culex, are primarily known for their roles in transmitting malaria and West Nile virus, respectively, and do not have the same association with Dengue transmission. Mansonia mosquitoes also have distinct ecological roles and do not typically serve as vectors for the Dengue virus. Hence, Aedes aegypti and Aedes albopictus are the correct focus for
