Which of the following diseases can be transmitted by mosquitoes?

West Nile Virus is a disease that is transmitted through the bites of infected mosquitoes. It is a crucial example of mosquito-borne illnesses, which also include diseases like Zika virus, dengue fever, and malaria. Mosquitoes act as vectors, facilitating the transmission of the virus from birds, which are typically the primary hosts, to humans and other animals. The possibility of contracting West Nile Virus can lead to severe health issues, including neurological diseases, making it particularly important for mosquito control efforts to focus on reducing mosquito populations to mitigate the risk of such diseases.

In contrast, the other options listed—common cold, influenza, and chickenpox—are not transmitted by mosquitoes. The common cold and influenza are primarily spread through respiratory droplets from coughs or sneezes, while chickenpox is spread via direct contact with the rash or respiratory droplets. Understanding the transmission methods of these diseases underscores the specific role that mosquitoes play in public health and the importance of targeted mosquito control measures.
