Which virus can be fatal to raptors and is spread by mosquitoes?

• A. Avian influenza
• B. West Nile Virus
• C. Canine distemper
• D. Newcastle disease

Answer: (B)

West Nile Virus is known to be fatal to raptors and is primarily spread through mosquito bites. This virus affects a variety of bird species, including eagles, hawks, and other raptors, often leading to neurological symptoms and, in many cases, death. The transmission cycle involves mosquitoes that become infected after feeding on an affected bird, subsequently transmitting the virus to other birds and various animals, including humans. In contrast, the other viruses listed have different transmission methods or hosts. Avian influenza, while serious, is typically spread via direct contact between infected birds or through contaminated environments rather than through mosquitoes. Canine distemper primarily affects canines and some other mammals but doesn't have the same impact on birds and is not transmitted through mosquitoes. Newcastle disease is a viral infection that affects birds but is largely spread through direct contact with infected birds or their bodily fluids rather than by insect vectors like mosquitoes. Understanding these distinctions is crucial for recognizing the risks faced by raptors concerning various diseases.
