Tick season poised to break records as bite numbers climb nationwide

CDC data suggest this year’s tick season could be the worst in years, with tick-bite ER visits running higher than average across most U.S. regions in 2026 and the Northeast leading; about 114 visits per 100,000 in late April. Roughly 31 million Americans are bitten annually and around 476,000 are treated for Lyme disease. Experts attribute factors like milder winters, earlier springs, snow insulation for ticks, and variable acorn mast years that boost wildlife hosts, which can fuel tick populations and disease. Prevention and tick checks are essential.
