- The Aedes mosquito, particularly Aedes aegypti and Aedes albopictus, is the chief vector responsible for transmitting the dengue virus.
- These mosquitoes are day-biting and thrive in urban environments, breeding in stagnant water collections.
- The dengue virus replicates within the mosquito, which then transmits it to humans through its bite. Other mosquito genera like Anopheles and Culex do not transmit dengue but are vectors for diseases like malaria and Japanese encephalitis, respectively.
- Control of Aedes populations is essential in preventing dengue outbreaks.
