CDC Warns 2026 Lyme Season Could Worsen as Tick-Bite ER Visits Hit 2017 High

Summary
April 23 CDC data showed U.S. emergency-room visits for tick bites at their highest level since 2017, a signal health officials say could foreshadow a severe 2026 Lyme disease season.
Warmer temperatures, shorter winters and shifting rainfall are helping ticks emerge earlier, survive longer and spread into new areas, while deer and housing growth near woodland habitats are raising human exposure.
More than 89,000 Lyme cases were reported by states in 2023, but public health experts estimate nearly 500,000 Americans contract it each year; about 90% of reported cases come from the Northeast, mid-Atlantic and Upper Midwest.
24 to 48 hours of tick attachment can transmit Lyme-causing bacteria, and untreated infections can lead to arthritis in about 60% of cases as well as rarer heart, brain and nerve complications.
A 2- to 4-week antibiotic course usually treats Lyme disease, while prevention still centers on repellents, protective clothing, tick checks and prompt removal until a vaccine now in late-stage testing becomes available.
