There has been an outbreak of Norovirus among Appalachian Trail (A.T.) 
hikers. This highly contagious virus causes your stomach and/or intestines 
to become inflamed, which leads to stomach pain, nausea, and diarrhea.

Norovirus is transmitted by contact with an infected person, contaminated 
food or water, or contaminated surfaces. The virus has a 12 to 48-hour 
incubation period and lasts 24 to 60 hours. Infected hikers may be 
contagious for 3 days to 2 weeks after recovery.

Outbreaks occur more often where people share untreated water sources and 
facilities for sleeping, dining, showering, and toileting. The virus can 
spread rapidly in crowded shelters and hostels.

Sanitation is key to avoiding and spreading Norovirus. Take the following 
steps to prevent contracting and spreading the illness:
•Treat all water by boiling, filtering, and/or treating with chemicals. To 
learn how best to treat your water, visit: www.cdc.gov/healthywater
•Do not eat out of the same food bag, share utensils, or drink from other 
hikers' water bottles.
•Wash your hands with biodegradable soap (200' from water sources) before 
eating or preparing food and after toileting.
•Be aware that alcohol-based hand sanitizer may be ineffective against 
•Follow Leave No Trace guidelines for disposing of human waste. For best
