Nepal Travel Health Advice
Travellers arriving from infected areas require a yellow fever vaccination certificate. Malaria is a health risk between June and September in the low-lying areas of Nepal, including Chitwan National Park, but not in the common trekking areas. Travellers should consult their doctor about whether malaria prophylaxis is necessary. Outbreaks of Japanese encephalitis occur annually, particularly between July and December, and vaccination is advised. Vaccinations are also recommended for hepatitis A, hepatitis B and typhoid. Those who will be in contact with animals, especially bats, may want to consider a rabies vaccination as well. Cholera outbreaks occur and food and water precautions should be followed.
Untreated water must be avoided; visitors should buy bottled water or purify their own. When trekking it is preferable to treat river water rather than leaving a trail of plastic bottles behind. Purifying water with iodine is the cheapest and easiest way to treat water. Altitude sickness is a real risk for trekkers: many people suffer from altitude sickness above 8,202ft (2,500m); if symptoms persist it is wise to descend as quickly as possible. The standard of care in hospitals varies, but there are traveller's clinics in Kathmandu and numerous pharmacies in the major towns. Medical insurance is essential, and should include air evacuation. All required medications should be taken into the country in their original packaging and accompanied by a signed and dated letter from a doctor detailing what they are and why they are needed.
