Indonesia Health & Vaccinations: What Travellers Need

Indonesia presents a standard set of tropical health considerations — none of which should discourage travel, but all of which reward preparation. This guide covers vaccinations, disease risk by region, medical facilities, and what to have in place before you go.

Always consult a GP or travel health clinic at least 6–8 weeks before departure. Some vaccine courses require multiple doses over several weeks. The information below is a general guide — a healthcare professional will assess your individual circumstances and itinerary.

Recommended Vaccinations

Hepatitis A

Recommended for all travellers to Indonesia. Hepatitis A is transmitted through contaminated food and water, and the risk exists even in tourist-oriented restaurants. The vaccine provides long-term protection after two doses and is widely available.

Typhoid

Recommended for most travellers, particularly those eating local food away from high-end tourist establishments. A single injectable or oral course provides protection for 3–5 years depending on the type. More important if you’re spending time in rural areas or at street food markets.

Rabies

Recommended for travellers who will be in rural areas, spending time with animals, trekking, or staying for more than a month. Rabies is present throughout Indonesia, including Bali — the Bali dog population is a known risk factor, as are monkeys at sites like the Ubud Monkey Forest.

The pre-exposure vaccine (three doses over 21 days minimum) does not eliminate the need for post-exposure treatment but simplifies it significantly and is potentially life-saving in remote areas where immediate treatment is not available.

If you have not had pre-exposure vaccination and are bitten or scratched by an animal, wash the wound thoroughly with soap and water for at least 15 minutes and seek medical attention immediately. Do not delay.

Japanese Encephalitis (JE)

Recommended for travellers spending extended time in rural or agricultural areas, particularly in rice-growing regions of Java, Bali, and Lombok. The risk is low for short-stay tourists in urban or beach areas. Discuss with your travel health clinic based on your specific itinerary.

Hepatitis B

Standard for travellers, particularly relevant if there’s any chance of medical treatment, unprotected sex, or tattooing during the trip. Often included in childhood vaccination schedules — check whether you’re already covered.

Routine Vaccinations

Ensure you’re up to date on MMR (measles, mumps, rubella), diphtheria, tetanus, and polio before travelling to Indonesia.

Malaria

Malaria is not a risk in Bali, Java, Lombok, or the Gili Islands. This applies to the overwhelming majority of tourist itineraries.

Malaria is present in certain remote areas:

• Papua and West Papua: highest risk; prophylaxis recommended
• Maluku: moderate risk in some areas
• Parts of Kalimantan: risk in inland and border areas
• Nusa Tenggara Timur (East Nusa Tenggara), including Flores: low to moderate risk in some rural areas

If your itinerary includes these regions, discuss anti-malarial medication with your GP — options include doxycycline, atovaquone-proguanil (Malarone), or mefloquine, depending on your medical history.

Even in malaria zones, mosquito avoidance (DEET repellent, long sleeves in the evening, sleeping under a net) remains essential regardless of prophylaxis.

Dengue Fever

Dengue is present throughout Indonesia, including Bali — it is not a risk confined to rural or jungle areas. The Aedes aegypti mosquito that carries dengue is a daytime biter, particularly active at dawn and dusk.

There is currently no widely available traveller vaccine for dengue (a vaccine exists with specific eligibility criteria — your GP will advise). Prevention depends entirely on mosquito avoidance:

• Use DEET-based repellent (minimum 20% DEET), applied every few hours
• Wear light-coloured, long-sleeved clothing in the evening
• Ensure your accommodation has window screens or use a mosquito net

Symptoms of dengue include sudden high fever (39–41°C), severe headache behind the eyes, muscle and joint pain, and rash. There is no specific antiviral treatment — rest, hydration, and paracetamol (not ibuprofen or aspirin, which can worsen bleeding risk) are the standard management. Seek medical attention if symptoms are severe.

Bali Belly and Stomach Illness

Traveller’s diarrhoea — locally nicknamed “Bali belly” — affects a significant proportion of first-time visitors in the first week. The cause is usually bacterial contamination in food or water rather than food quality.

Prevention:

• Drink only bottled or filtered water — including for brushing teeth
• Be cautious with ice in basic establishments
• Eat at busy warungs (high turnover = fresh food)

Treatment:

• Oral rehydration salts (ORS) — the most important intervention
• Imodium (loperamide) for symptom relief
• Rest

Most cases resolve within 48–72 hours. See a doctor if symptoms persist beyond three days, include a high fever, or involve blood in the stool.

Hospitals and Medical Facilities

In Bali:

• BIMC Hospital — branches in Kuta and Nusa Dua; tourist-friendly, English-speaking staff, accepts international insurance; suitable for most non-emergency situations
• Siloam Hospitals Bali — in Denpasar; full-service private hospital
• SOS Medika Klinik — International SOS clinic in Kuta; travel-medicine specialists, coordinates evacuations

In Jakarta:

• Siloam Hospitals (multiple locations) — most comprehensive private hospital network
• RS Pondok Indah — private hospital with international-standard care

For serious emergencies: Medical evacuation to Singapore or Darwin (Australia) is the standard for cases requiring specialist care. International SOS and similar medical assistance companies coordinate these. This is why travel insurance with medical evacuation cover is essential — evacuation costs can easily exceed USD 50,000.

Pharmacies

Indonesian pharmacies (apotek) are found in every town and most villages. Common medications are widely available without a prescription, including:

• Paracetamol and ibuprofen
• Oral rehydration salts
• Imodium
• Antihistamines
• Topical antibiotics and wound care
• Oral antibiotics (some available over the counter, though this is changing)

Bring personal prescription medications in sufficient quantity for your trip. Specific brands and formulations may not be available in Indonesia, and some prescription medications are controlled differently than in your home country.

Travel Insurance

Travel insurance is essential for Indonesia. Prioritise:

• Medical evacuation cover — minimum USD 100,000; ideally unlimited. Evacuation to Singapore is the benchmark
• Emergency medical treatment — ensure it covers hospitalisation at private hospitals
• Activity cover — confirm trekking, diving, and motorbike riding are not excluded
• Cancellation and disruption — useful given Indonesia’s weather and volcanic disruption risk

Do not travel without it.
