Heat-Related Illnesses and Tick Season Trends in the U.S.
US · Published May 27, 2026
According to a recent update from Your Local Epidemiologist, heat-related illnesses are becoming a concern in parts of the United States, particularly in the Midwest and Southeast.
While the heat risk is not widespread across the country, moderate levels are expected in these regions this week.
Additionally, tick activity, which typically peaks during this time of year, is showing a decline, especially in the Northeast and Midwest.

Why It's Important?

The moderate heat risk in the Midwest and Southeast could pose challenges for vulnerable populations, including children, the elderly, and individuals with pre-existing health conditions such as asthma. Prolonged exposure to heat can lead to dehydration, heat exhaustion, or heat stroke. On the other hand, the decline in tick activity is good news for residents in the Northeast and Midwest, reducing the risk of tick-borne illnesses such as Lyme disease. However, individuals should remain cautious and continue preventive measures against ticks.
