What type of pathogens cause the most important mosquito-borne diseases in Michigan?

The most significant mosquito-borne diseases in Michigan are primarily caused by viruses. These viral pathogens include notable illnesses such as West Nile virus and Eastern equine encephalitis. These viruses are transmitted to humans and animals through the bites of infected mosquitoes, demonstrating a direct relationship between the pathogen and vector in the context of disease emergence and public health concern.

Bacteria, fungi, and protozoans do exist in various forms and can cause diseases, but they do not present the same level of concern or incidence in the context of mosquito-borne diseases in Michigan as viruses do. The focus on viral pathogens is pivotal because it aligns with the main health advisories and control measures taken by public health officials and mosquito control agencies in response to outbreaks and the monitoring of mosquito populations.
