Tick Bites Surge Across Northeast and Midwest, Prompting Health Warnings
US · Published May 18, 2026
Emergency room visits for tick bites have reached their highest levels for this time of year since 2017, according to the Centers for Disease Control and Prevention (CDC).
Warmer temperatures, driven by climate change, have contributed to increased tick activity, particularly in the Northeast and Midwest regions of the United States.
The CDC reports that Lyme disease, the most common tick-borne illness in the U.S., affects an estimated 476,000 people annually.

Why It's Important?

The surge in tick activity poses significant health risks, particularly in the Northeast and Midwest regions. Lyme disease, which can cause a range of symptoms from fever and fatigue to severe joint pain and neurological issues, is the primary concern. The blacklegged tick and Western blacklegged tick are the main carriers of the disease. In some areas, up to 50% of ticks may be infected. Other tick-borne illnesses, which can be transmitted in as little as 15 minutes, also present risks. Populations in high-risk states, including Connecticut, New York, and Wisconsin, are especially vulnerable.
