Has Tick Bitting Season Peaked

While not every tick bite can pass the Lyme disease virus to a person, avoiding bites is the best way to prevent this severe disease in 2025. Since tick bites can occur year-round, they generally peak during the warmer months in the northeastern United States, between April and September.

However, this year has started differently.

According to new data posted by the U.S. CDC's Tick Bite Data Tracker, the number of emergency room visits related to a tick bite has been decreasing over the past month.

The CDC's data may not accurately reflect the actual spread of Lyme disease into the Midwest in 2025.

Last year, the Michigan Department of Health and Human Services confirmed Lyme disease was the most common tick-borne disease in Michigan. Cases in Michigan have increased by 168% over the last five years.

As a Lyme disease prevention update, the U.S. Food and Drug Administration has not yet approved a vaccine.

But an innovative Lyme disease vaccine candidate (VLA15) is progressing in late-stage clinical trials.
