Lyme disease and other tick-born diseases are a significant cause of illness in New Hampshire. Measures to avoid getting bitten by a tick include:

  • Using insect repellent according to product label directions
  • Wearing protective clothing such as long-sleeved shirts and long pants
  • Staying away from tick-infested areas such as overgrown grass and brush
  • Perform tick checks regularly

If you discover you have been bitten by a tick, the New Hampshire Department of Health and Human Services recommends the following actions to prevent tick-borne disease:

  • Remove the tick immediately by grasping the head with fine-nosed tweezers as close to the skin as possible, using a slow, steady, upward motion to minimize the chances of leaving the head behind. Clean the bite area with soap and water or alcohol.
  • Consult a healthcare provider if the tick has been attached for at least 36 hours for possible treatment with a prophylaxis (single dose of the antibiotic doxycycline). This prophylaxis can only be given to people 8 years of age or older and must be given within 72 hours of tick removal. One study found that if this was done, the prophylactic treatment was 87% effective in preventing early Lyme disease.
  • If concern of illness arises after the tick bite, whether or not prophylactic treatment was administered, or you do not recall having been bitten by a tick but notice that you have a rash or a fever, a healthcare provider should be contacted to discuss whether testing or treatment is needed.
