Yellow fever is transmitted by which type of insect?

• A. Ticks
• B. Bees
• C. Mosquitoes
• D. Flies

Answer: (C)

Yellow fever is predominantly transmitted by mosquitoes, particularly those in the Aedes genus, such as Aedes aegypti. This transmission occurs when an infected mosquito bites a person, injecting the virus into the bloodstream. The role of mosquitoes as vectors for yellow fever is significant, as they can thrive in urban areas as well as in jungle environments, making outbreaks more likely in regions where these mosquitoes are present.

The other insects listed, such as ticks and bees, do not serve as vectors for yellow fever. Ticks are known to transmit other illnesses, but they do not carry the yellow fever virus. Bees play a crucial role in pollination and can sometimes cause allergic reactions in humans, but they do not have any association with the transmission of yellow fever. Flies, while they can carry pathogens, are also not responsible for transmitting this specific virus. Thus, mosquitoes are clearly identified as the primary carriers of the yellow fever virus.
