Tick bites surge across the U.S., driving ER visits higher
Tick activity is rising in the Northeast and Midwest as warmer temperatures expand tick habitats, leading to a peak in tick-bite emergency-room visits for this time of year since 2017. Lyme disease remains the most common tick-borne illness, with about 476,000 US cases treated annually, and climate change is aiding the spread. To reduce risk, people outdoors should perform thorough tick checks on skin and clothing, shower after outdoor time, inspect hidden areas, and remove attached ticks promptly, since Lyme transmission typically requires 24–36 hours of attachment (other tick-borne diseases can transmit more quickly).
