Nepal travel health: vaccines, water safety, and medical care

Vaccinations widely recommended before a Nepal trip

Routine vaccines — MMR, Tdap, polio, and an up-to-date flu shot — should be current for any trip, Nepal or otherwise. On top of those, hepatitis A and typhoid are the two travel-specific vaccines most consistently recommended across travel-health sources for Nepal, given food and water exposure that is present throughout the country and elevated on the trekking trail. Japanese encephalitis is recommended specifically for travellers spending a month or longer in Nepal, or doing rural travel, trekking, or camping — particularly during the rainy and post-monsoon months — rather than for a short city-and-tourist-hub visit.

Treat this as a widely recommended starting point to discuss with a professional, not a complete or authoritative checklist. NepalPick could not independently fetch CDC’s or the NHS’s own travel-health pages this run (see sources note); the recommendations above are cross-referenced across several independent travel-clinic summaries instead. Confirm your own vaccination plan with a travel clinic or doctor 4–6 weeks before departure — they will factor in your itinerary, trip length, and medical history in a way this page cannot.

The 2026 Japanese encephalitis outbreak

The single most actionable fact for a traveller: Nepal currently has no Japanese encephalitis vaccine available for adults domestically — the existing national programme covers children, and a planned adult catch-up campaign for high-risk districts remains unfunded as of the sources checked this run. If your itinerary and duration indicate JE vaccination, arrange it through a travel clinic before you arrive in Nepal, not on arrival.

Water and food safety

Tap water is not considered safe to drink anywhere in Nepal, including in upscale Kathmandu and Pokhara hotels. Bottled water — widely available in cities, tourist areas, and along established trekking routes — or water boiled for at least three minutes are the two safe options. The same caution extends to ice and to raw salads or fruit that may have been rinsed in tap water, especially from street food.

Traveller’s diarrhoea is commonly reported as the single most common health issue for visitors to Nepal, caused by contaminated food or water — bacterial causes and Giardia are the most frequently cited, alongside Cyclospora cayetanensis, a protozoal parasite reported as endemic to Nepal with transmission concentrated May to October. Standard prevention: peel fruit yourself, avoid raw salads washed in tap water, prefer hot freshly cooked food, and skip locally made ice or juice. If diarrhoea does occur, most cases are mild and self-limiting with hydration and rest; seek medical care for high fever, blood in stool, or symptoms lasting more than a few days rather than treating it as something to push through.

Malaria: a lowland Terai risk, not a trekking-altitude one

Malaria transmission in Nepal is confined to lower elevations, generally below about 2,000 metres, and the risk is not uniform even within the Terai. At Chitwan National Park specifically, reported risk is very low and standard bite-prevention measures (repellent, covering up at dusk, a treated bed net) are generally considered adequate without preventive medication for a short visit. At Bardiya National Park, risk is reported higher during the summer monsoon months (roughly June to September) for travellers staying longer in rural areas, where a travel clinic may routinely recommend antimalarial medication; outside that window, for a shorter visit with easy access to medical care, prophylaxis is typically not considered necessary. There is no malaria transmission risk in Kathmandu, Pokhara, or at any trekking altitude — the mosquitoes that carry it do not survive there.

This maps directly onto several of NepalPick’s own destinations: Bardiya & Khata Corridor, Koshi Tappu, and Shuklaphanta & Rana Tharu villages all sit in this lowland risk zone (see the full list of Nepal destinations for others). Whether prophylaxis makes sense for your specific trip depends on the exact park, season, and length of stay — a question for a travel-health professional, not a fixed rule this page can give you. Antimalarial drug choice (atovaquone-proguanil, doxycycline, mefloquine, and others each have trade-offs) is a prescription decision, not something to self-select.

Rabies: dogs, and Kathmandu’s specific monkey-bite risk

Nepal is rabies-endemic, and free-roaming dogs are the most common source of exposure countrywide. A well-documented, Kathmandu-specific risk is monkey bites and scratches at Swayambhunath (the “monkey temple”) and around Pashupatinath — an older but still widely cited CIWEC Clinic study found monkey bites and scratches accounted for 43% of all animal exposures reported by tourists in Kathmandu, with roughly half of all traveller exposures occurring at or near Swayambhunath specifically. Feeding or approaching temple monkeys makes a bite or scratch more likely; keep a respectful distance and do not offer food.

After any bite or scratch, even one that looks trivial: wash the wound thoroughly with soap and running water for a sustained period (commonly cited as around 15 minutes), then seek medical care promptly. Rabies post-exposure treatment is effective even if care is not immediate, but it should never be skipped or indefinitely delayed on the assumption that a minor-looking wound is not a real risk.

Finding medical care while travelling

Kathmandu has Nepal’s widest range of private, international-standard hospitals and travel-medicine-focused clinics — CIWEC Hospital (established 1982 specifically for travel medicine) among the best known — and Pokhara has its own established private hospitals with 24/7 emergency care, including a CIWEC facility. Outside those two hubs and in remote trekking areas, medical access thins quickly, and a serious emergency may mean transfer to Kathmandu or Pokhara rather than local treatment.

Plan for payment reality: some clinics accept cards, others are cash-only, and travellers should be prepared to pay before treatment begins in many cases rather than assuming direct insurer billing. This is exactly why the distinction between pre-authorised and pay-and-claim-later insurance matters — see Nepal travel insurance for how that works, rather than repeating it here.

Pharmacies and over-the-counter medication

Pharmacies are widely available in Nepal’s cities and tourist areas, and many medicines that require a prescription elsewhere can be bought over the counter. That accessibility is convenient but not a substitute for medical judgement: buying from an established pharmacy, or after a doctor’s guidance, is safer than self-diagnosing and self-medicating with an unfamiliar product. This is a thinly sourced topic online — most available detail is forum discussion rather than an authoritative source — so this page keeps to that general, cautious framing rather than naming specific pharmacies or products.
