Dengue fever is primarily transmitted by which mosquito species?

• A. Anopheles mosquito
• B. Aedes aegypti mosquito
• C. Culex mosquito
• D. Tsetse fly

Answer: (D)

Dengue fever is transmitted by the Aedes aegypti mosquito, a day-biting species that thrives in urban environments and breeds in small containers of standing water. When a person is viremic, a female Aedes mosquito can pick up the virus during a blood meal and later transmit it to another person with its next bite. This pattern distinguishes it from other disease vectors: Anopheles mosquitoes spread malaria, Culex species can carry other viruses like West Nile, and the tsetse fly transmits Trypanosoma parasites causing sleeping sickness. So, dengue's primary vector is Aedes aegypti.
