Which disease is notably linked to mosquito transmission?

The association of West Nile virus with mosquito transmission is well-documented and is a critical aspect of its epidemiology. West Nile virus is primarily spread to humans through the bite of infected mosquitoes, particularly species that feed on birds, which serve as the primary reservoir. This transmission pathway emphasizes the role of mosquitoes in the lifecycle of the virus, leading to outbreaks that can have significant public health implications. In contrast, the other diseases listed do not primarily involve mosquito transmission; for instance, avian influenza is primarily transmitted through contact with infected birds rather than through mosquitoes, canine parvovirus is a viral infection that spreads through direct contact with infected dogs or contaminated environments, and rabies is transmitted through the bite of infected animals, most commonly from mammals like bats and raccoons, rather than mosquitoes. This specificity makes West Nile virus a standout example of a disease significantly linked to mosquito transmission.
