Early Spring Tick Surge Pushes ERs Toward Spike in Bites
A CDC tick-bite tracker shows an early, larger-than-usual surge in emergency department visits across the U.S., rising from 28 to 114 bite-related visits per 100,000 between March and April as warmer spring weather expands tick activity and ranges. Tick-borne illness risk is driven by the black-legged tick (Lyme disease) and the lone star tick (red meat allergy), with spread into new areas. Most bites don’t require ED care; prompt tick removal is advised and doctors may treat suspected infections with doxycycline before tests return. Tick season generally runs March through October, peaking in late May, with about 31 million bites annually and Lyme disease affecting roughly 476,000 people each year.
