US Experiences Early Tick Season with High Emergency Room Visits for Bites

An early tick season is occurring across the United States, with elevated numbers of tick bites reported. The Centers for Disease Control and Prevention (CDC) tracking system indicates that weekly rates of emergency room visits for tick bites are the highest for this time of year since 2017 in all regions except the south-central United States.

Hospital emergency departments provide data to this system, though it does not include cases where individuals did not seek hospital care. Dr. Alina Filozov, an infectious disease doctor at Middlesex Hospital in Middletown, Connecticut, stated that higher exposures could lead to more cases of tick-related infections.

The CDC issued an advisory this week urging vigilance against ticks. Alison Hinckley, a CDC Lyme disease expert, said tick bites typically increase in May, but current data indicates action is needed now.

Influencing Tick Populations Ticks are eight-legged bloodsucking parasites that feed on animals and sometimes humans. Their populations vary by year and depend on factors such as warm, humid weather and availability of hosts like deer and mice. The CDC estimates 476,000 people are treated for Lyme disease annually, the most common tick-borne illness, along with others like Rocky Mountain spotted fever and alpha-gal syndrome, a red meat allergy.

Infections are typically treated with antibiotics. This year in the Northeast, most observed ticks have been large adults, with juvenile nymphs expected to become more common soon. Nymphs are harder to detect and may remain attached longer, increasing infection risk.

State officials stated that 40% of these ticks tested positive for Lyme disease bacteria. Scott Williams, a tick researcher at the station, attributed tick population expansion to high mouse numbers over the past two years. Megan Linske, a wildlife biologist at the agency, said current data provides an early snapshot and expects the issue to worsen with ticks spreading to more areas.

Systematic tick sampling by researchers will take months to assess population changes, and it will also take time to determine if there is a surge in diseases.

advise avoiding wooded and grassy areas where ticks perch on low vegetation. Recommendations include walking in the middle of paths, wearing light-colored clothing treated with permethrin, and using EPA-registered insect repellents. If a tick is found, remove it immediately. Medical attention is not necessary unless the tick has been attached for days or symptoms like a rash develop.
