Health in Indonesia — Vaccines, Hospitals, Bali Belly, and Insurance

Pre-trip vaccines, dengue and malaria, traveller's diarrhoea, rabies risks, hospital options, and travel insurance — the health bundle for travel in Indonesia.

5 min read

Indonesia's health risks for visitors are mostly modest — mainly traveller's diarrhoea ("Bali belly"), mosquito-borne illness in certain areas, and the standard risks of travel (road accidents, sun exposure). Quality private hospitals exist in major cities; public healthcare is improving but variable. This guide covers what to know before going and what to do if something goes wrong.

Pre-trip vaccines

Consult your home country's travel health service 4-6 weeks before travel. Standard recommendations for Indonesia:

Routine:

  • Tetanus, diphtheria, pertussis — be up to date
  • Measles, mumps, rubella (MMR)
  • Polio
  • COVID-19

Recommended for most visitors:

  • Hepatitis A — food and water transmitted; very common in Indonesia
  • Typhoid — food and water transmitted
  • Hepatitis B — recommended for longer stays or specific activities

For longer stays or specific destinations:

  • Japanese encephalitis — for extended rural stays during the wet season
  • Rabies pre-exposure — for cyclists, runners, or anyone working with animals; rabies is endemic in Bali and many other areas
  • Yellow fever — only required if you're arriving from a yellow-fever country

Not generally needed:

  • Cholera (low risk for typical tourist exposure)

Allow 2-4 weeks for vaccine courses; some (Hep A, Hep B, JE) require multiple doses.

Dengue and other mosquito-borne illness

Dengue is present throughout Indonesia, with peaks during and after the wet season (November-May). Symptoms: high fever, severe body aches, headache, rash. No specific treatment; supportive care only. Most cases resolve in a week but severe dengue can be life-threatening.

Prevention:

  • DEET-based repellent (30%+) for skin
  • Permethrin-treated clothing for high-risk areas
  • Long sleeves and trousers at dawn and dusk
  • Mosquito nets at night in non-air-conditioned accommodation

Malaria is present in eastern Indonesia (Papua, Maluku, eastern Nusa Tenggara, parts of Sumatra). NOT present in Bali, Java, or the typical tourist areas. For travel to malaria areas, prophylaxis (atovaquone-proguanil, doxycycline, or mefloquine) is recommended. Consult a travel clinic.

Japanese encephalitis is a rare but serious mosquito-borne illness in rural areas. Vaccine for longer stays in rural Java/Bali during wet season.

Zika is present at low levels; precautions advised for pregnant travellers.

Bali belly (traveller's diarrhoea)

By far the most common health issue for visitors. Most cases are mild (1-3 days of stomach upset) caused by unfamiliar bacteria in food and water.

Prevention:

  • Drink only bottled or filtered water (avoid tap water)
  • Avoid ice in less-developed venues (most modern ice is fine)
  • Eat at busy, popular places (high turnover = fresher food)
  • Avoid raw vegetables and unpeeled fruit in less-controlled venues
  • Wash hands frequently, carry hand sanitiser

Treatment:

  • Oral rehydration salts (ORS) — the most important intervention; carry them
  • Imodium (loperamide) for symptom control
  • Rest and bland food
  • See a doctor if: fever, blood in stool, severe symptoms, or no improvement in 48 hours

A short course of antibiotics (azithromycin or ciprofloxacin) is often prescribed by travel doctors for self-treatment. Carry as backup.

Rabies

Rabies is endemic in Indonesia, including Bali. The risk to visitors is generally low but real. Sources include dogs, monkeys, bats, and cats.

If bitten or scratched:

  • Wash the wound thoroughly with soap and water for 15 minutes
  • Get to a hospital that stocks human rabies immunoglobulin (HRIG) and rabies vaccine within 24 hours
  • Post-exposure treatment is highly effective if started promptly

In Bali, BIMC Hospital, Siloam Hospitals, and Sanglah Hospital have rabies post-exposure treatment. In Jakarta, the major private hospitals all have it.

Pre-exposure vaccination (3 doses over 21-28 days) simplifies post-exposure treatment but doesn't replace it.

Sun and heat

The equatorial sun is intense:

  • SPF 50+ sunscreen, reapplied every 2 hours
  • Hat and sunglasses
  • Shade between 11am-3pm when possible
  • Heat exhaustion warning signs (nausea, headache, confusion) — rest, water, electrolytes
  • Sunburn is common on the first 1-2 days; pace your sun exposure

Road safety

Road traffic accidents are statistically the leading cause of serious injury and death for foreign visitors:

  • Don't ride scooters if you've never ridden one before — Bali is not the place to learn
  • Wear a helmet always — provided helmets are often poor quality; consider buying your own
  • Don't drink and drive
  • Be aware of road hazards — sudden potholes, animals, unmarked turns
  • Avoid riding at night when possible
  • Have travel insurance that covers scooter accidents (some policies exclude these)

If you're involved in an accident, get to a private hospital immediately. Indonesian public hospitals are improving but private facilities are usually faster for foreigners.

Hospitals

Major private hospitals (international standard):

Jakarta:

  • Siloam Hospitals (Kebon Jeruk, TB Simatupang, others)
  • RS Pondok Indah (multiple locations)
  • Mayapada Hospital
  • SOS Medika Klinik (emergency clinic, 24-hour)

Bali:

  • BIMC Hospital (Kuta, Nusa Dua)
  • Siloam Hospitals Bali (Denpasar)
  • Kasih Ibu Hospital (Denpasar)
  • RS Bali Mandara (Denpasar)

Yogyakarta, Surabaya, Medan, and other major cities have Siloam, Mayapada, or other private hospital chains.

Public hospitals (RSUD, RS Pemerintah): adequate for emergencies, often cheaper, but waits can be long and English-speaking staff variable.

Costs: Private hospital outpatient consultations: Rp 300,000-1,000,000 (USD 19-63). Inpatient stays: substantially more — a serious illness can cost thousands of USD. Travel insurance is essential.

Travel insurance

Essential for any Indonesia trip. Recommended coverage:

  • Medical evacuation: minimum USD 100,000
  • Medical treatment: minimum USD 50,000
  • Activity coverage: especially scooter, diving, hiking
  • Cancellation and luggage

Well-regarded providers:

  • World Nomads (popular for active travel)
  • SafetyWing (nomad-friendly)
  • Allianz Travel
  • AXA
  • Many country-specific options

Read the policy carefully — many policies exclude scooter accidents unless you have a motorcycle licence and IDP.

Dental and routine

Bali in particular has become a popular destination for dental tourism and elective procedures. Quality private dental clinics in Bali offer:

  • Cleaning: USD 30-60
  • Fillings: USD 30-100
  • Crowns: USD 200-500
  • Implants: USD 1,000-2,500

Recommended Bali dental: ARC Dental, BIMC Dental, Bali 911 Dental.

For elective surgery (orthopaedic, cosmetic), Jakarta and Bangkok are larger markets, but Bali is growing.

Other practical

  • Pharmacies (apotek) are widely available; antibiotics are often available without prescription
  • Bring your own prescription medications — names and availability vary in Indonesia
  • Tick a recent prescription off with your travel doctor before going
  • Carry a copy of vaccine records and a list of current medications
  • WHO recommendations on Indonesia: check who.int for current health advisories
  • CDC Travel (US) or NaTHNaC (UK) or your country's equivalent for current advice

For most visitors making standard tourist trips, the health risks are real but manageable with sensible precautions. Bali belly is almost universal; serious illness is rare.
