Which potential pathogens contracted from mosquitoes are most concerning in Michigan?

The concern surrounding potential pathogens contracted from mosquitoes in Michigan primarily centers on the viruses that have shown prevalence in the region. The correct response emphasizes the public health significance of West Nile virus, St. Louis encephalitis, and La Crosse encephalitis.

West Nile virus is the most commonly reported mosquito-borne illness in the United States, including Michigan, and can lead to severe neurological diseases. Its presence in the state has been documented, and it remains a critical focus for mosquito control and public health efforts.

St. Louis encephalitis and La Crosse encephalitis are also important pathogens found in the Midwest. St. Louis encephalitis, while less frequently reported in recent years, poses considerable risks for severe illness, particularly among vulnerable populations, and is known to circulate in Michigan. La Crosse encephalitis, primarily affecting children, has been reported in several states, including Michigan, and can lead to serious complications.

In contrast, the other options feature diseases that either do not present a significant threat due to their limited presence in Michigan or have a more geographically specific prevalence. For instance, diseases like malaria and Zika virus, while concerning, are not as commonly transmitted through local mosquitoes in Michigan as the pathogens identified in the correct response
