Nepal Travel Health Advice
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. Outbreaks of Japanese encephalitis occur annually, particularly between July and December; vaccination is advised. Cholera outbreaks occur and food and water precautions should be followed. Untreated water should be avoided; visitors can 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 trekkers may suffer from altitude sickness above 8,202ft (2,500m); if symptoms persist it is wise to descend as quickly as possible. 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, which should include air evacuation. Travellers arriving from infected areas require a yellow fever vaccination certificate.
