Tick guide for Alaska

About ticks in Alaska
Ticks occur in Alaska, but the state’s public-health context differs from many parts of the contiguous United States. Alaska health guidance reports that locally acquired Lyme disease and Rocky Mountain spotted fever have not been documented; reported cases affected residents exposed during travel outside the state. Tularemia does occur in Alaska and may be associated with tick bites or infected animals.

Practical awareness
Residents and visitors should check people, pets and equipment after outdoor activity or travel. Introduced ticks can arrive on animals, people or luggage. Location records should not be interpreted as proof of disease transmission.

Using this guide
Species evidence will be added only where reviewed Alaska occurrence records can be connected confidently to an existing Tick ID Centre profile.
