Preventing Tickborne Diseases

Tickborne diseases can be serious illnesses and can affect people of any age. Lyme disease, anaplasmosis, babesiosis and Powassan virus are transmitted by the bite of the black-legged tick (lxodes scapularis), formerly known as the deer tick.

Black-legged ticks have four life stages: eggs, larvae, nymphs and adults. The black-legged tick nymphs are most active in the late spring through summer months (usually May through August). You can learn more about Lyme disease and other tickborne diseases from the NH Department of Health and Human Services (NH DHHS).

The NH DHHS has also published a "State of New Hampshire Tickborne Disease Prevention Plan". This excellent resource provides additional background information about the tickborne diseases documented in NH and may be useful for those seeking more information about how to begin modifying their behavior and physical landscape to reduce the risk of tickborne disease.
