What is the primary vector for Dengue fever?

The primary vector for Dengue fever is the Aedes aegypti mosquito. This particular species is well-adapted to urban environments and is commonly found in tropical and subtropical regions where conditions are optimal for its life cycle and breeding. The Aedes aegypti mosquito typically prefers to breed in stagnant water in close proximity to human habitation, making it an effective transmitter of the dengue virus.

Infected mosquitoes transmit the virus to humans through their bites. When a person is bitten by an Aedes aegypti mosquito carrying the virus, they can develop symptoms of Dengue fever, which can range from mild to severe. This direct relationship between the Aedes aegypti mosquito and the transmission of the disease underscores the importance of mosquito control measures in preventing outbreaks.

Other choices represent different organisms that are not responsible for the transmission of Dengue fever. Anopheles mosquitoes are known vectors for malaria, black-legged ticks are associated with Lyme disease, and macaws do not have any role in the transmission of infectious diseases like dengue, focusing instead on their natural behaviors and ecological roles.
