Michigan Lyme disease cases nearly quadrupled
Michigan is grappling with a sharp increase in Lyme disease cases, with numbers nearly quadrupling from 553 in 2022 to 2,167 in 2025, according to the Michigan Department of Health and Human Services. This surge is largely due to the expanding tick populations, particularly in suburban and urban areas, where human contact is more frequent. Disease ecologist Jean Tsao from Michigan State University points out that ticks are becoming increasingly common in southern Michigan, correlating with higher population densities. The state's designation by the CDC as a 'high-incidence jurisdiction,' with over 10 confirmed cases per 100,000 people for three consecutive years, underscores the severity of the situation, requiring immediate and sustained attention.
