What is the method of transmission for the West Nile virus?

The method of transmission for the West Nile virus is through an insect vector, specifically mosquitoes. This means that the virus is not spread directly from person to person or through interactions with contaminated surfaces, water, or through the air. Instead, mosquitoes become infected when they feed on birds that harbor the virus. Once infected, these mosquitoes can then transmit the virus to humans and other animals through their bites. This highlights the importance of controlling mosquito populations and avoiding mosquito bites, especially in areas where the West Nile virus is prevalent. Understanding this transmission method is crucial for effective prevention and control of the virus's spread.
