Question: 1 / 400

Which virus is primarily transmitted by infected mosquitoes?

Zika Virus

West Nile Virus

The Zika Virus is predominantly transmitted by infected mosquitoes, specifically the Aedes species, making it the correct choice for this question. This virus is known for its association with birth defects when pregnant women are infected. Understanding the transmission vectors is crucial for controlling outbreaks and implementing effective public health interventions. Although West Nile Virus is also transmitted by mosquitoes, the specific focus on the primary vector for the Zika Virus highlights its significance in reproductive health and vector-borne disease research.

The other options, HIV and Hepatitis B, are primarily transmitted through different routes such as sexual contact and sharing contaminated needles, rather than through insect vectors. Therefore, knowledge of vector transmission is vital in distinguishing these diseases in public health contexts.
