Question

Yellow fever is caused due to the human-to-human transmission by-

• A. Aedes aegypti
• B. Culex
• C. Dermacentor andersoni
• D. Mycobacterium tuberculosis

Hint:

Recall the specific mosquito species responsible for the transmission of yellow fever and its role as a vector.

Answer 1

The Correct Option is A

Yellow fever, a viral hemorrhagic disease, is primarily transmitted by the Aedes aegypti mosquito. This mosquito acts as a vector, spreading the virus between humans or from infected monkeys to humans. The disease affects the liver and kidneys, causing jaundice and sometimes fatal complications. Other organisms listed, such as Culex, are vectors for other diseases, and Mycobacterium tuberculosis is a bacterium unrelated to yellow fever.
