Which diseases are commonly transmitted by mosquitoes in Michigan?

The correct focus here is on the diseases relevant to Michigan and those that mosquitoes commonly transmit in that region. West Nile Virus and Eastern Equine Encephalitis (EEE) are indeed two significant mosquito-borne diseases found in Michigan.

West Nile Virus has been present in the state since 2001 and is transmitted primarily by Culex mosquitoes. While many people who contract West Nile Virus may not show symptoms, it can lead to serious neurological conditions in some cases, particularly among the elderly or immunocompromised individuals. Similarly, Eastern Equine Encephalitis is less common but poses a severe risk, with a high rate of mortality associated with the disease. It is mainly spread by mosquitoes in wetlands, where the associated birds harbor the virus.

The other options include diseases that are either non-existent in Michigan or are not significantly transmitted by local mosquito populations. Lyme Disease, for example, is a tick-borne illness and is not transmitted by mosquitoes. Meanwhile, Chikungunya, Malaria, Dengue Fever, and Yellow Fever are diseases that are not endemic to Michigan, with conditions not conducive for their transmission by local mosquito species. Therefore, the focus on West Nile Virus and Eastern Equine Encephalitis reflects the reality
