Why Yale Medicine?
  • Lyme disease was first identified here, and we remain at the forefront of treating tick-borne illnesses.
  • We offer a full range of tests to detect tick-borne illnesses.
  • We treat hundreds of patients each year with tick-borne illnesses.

A tick bite can turn a pleasant walk in the woods or an afternoon in the garden into a cause for concern. But being bitten by a tick isn’t a reason for immediate panic. Tick-borne illnesses such as Lyme disease can be treated effectively if caught early. Doctors in Yale Medicine’s Department of Emergency Medicine treat hundreds of patients each year for tick-borne illnesses, with excellent results.

It can be difficult to know if you’ve been bitten by a tick because the bite doesn’t hurt and you may not even feel it, says Harry Moscovitz, MD, assistant professor of Emergency Medicine at Yale School of Medicine.

The way to know for sure is to find a tick attached to you. The bite is potentially dangerous if the tick has fed, causing it to become swollen because of ingested blood.

Many people find the tick attached because they'll touch the area and they realize it's the tick that's attached there, Dr. Moscovitz says.
