Indonesia Travel Health Guide for US Travelers
A physician-reviewed health and safety guide for Americans traveling to the Republic of Indonesia
As of early 2026, the U.S. Department of State advises Americans to Exercise Increased Caution in Indonesia due to terrorism and natural disasters. The Papua and West Papua provinces are assessed at Level 3 (Reconsider Travel) due to civil unrest and violence. Terrorism remains an ongoing threat throughout Indonesia. Always check the latest advisory at travel.state.gov before departing.

Before You Travel to Indonesia
Indonesia — an archipelago of over 17,000 islands spanning a distance wider than the continental United States — is one of the world's most extraordinary destinations. From Bali's temples and rice terraces to Komodo's dragons, Borneo's rainforests, and Java's volcanic landscapes, Indonesia rewards adventurous travelers. Health preparation varies enormously by destination — Bali requires relatively modest preparation, while remote islands, Papua, and jungle areas demand comprehensive planning. See a travel medicine physician at least 4–6 weeks before departure.
Visit a Travel Clinic
See a travel medicine physician at least 4–6 weeks before departure. Health risks vary significantly by island and region. Bring your full itinerary and immunization record. Malaria prophylaxis may or may not be needed depending on your specific destination.
Get Travel Insurance
Comprehensive travel insurance with medical evacuation coverage is essential. Healthcare in Bali and Jakarta has improved significantly but is still limited for complex conditions. In remote islands, Papua, and Borneo, evacuation to Singapore, Kuala Lumpur, or Australia may be required.
Documents & Registration
Enroll in STEP at step.state.gov. US citizens can enter Indonesia visa-free for up to 30 days or obtain a Visa on Arrival (VoA) for 30 days (extendable once). Ensure your passport is valid for at least 6 months.
Pack a Medical Kit
Bring all prescription medications, DEET repellent (≥30%), oral rehydration salts, antidiarrheal medication, a broad-spectrum antibiotic (per doctor), water purification for remote areas, and SPF 50+ sunscreen. For diving, ensure you have dive medical insurance and know the nearest hyperbaric chamber.
Water & Food Safety
Tap water is not safe to drink anywhere in Indonesia. Use sealed bottled or purified water throughout your stay. At upscale Bali resorts, water safety is generally managed — always verify. In remote areas, purify all water. Exercise caution with street food — choose busy vendors with high turnover.
Cash & Payments
The Indonesian Rupiah (IDR) is the local currency. Credit cards are accepted at hotels and restaurants in Bali and Jakarta. Cash is essential in local markets and outside major tourist areas. ATMs are widely available in tourist areas but less reliable in remote islands. Bring some US dollars as backup.
Yellow Fever in Indonesia
About Yellow Fever
Indonesia has no endemic yellow fever — the transmitting mosquito species is not established here. However, Aedes aegypti is ubiquitous throughout the archipelago and transmits dengue, Zika, and chikungunya. Indonesia consistently records among the highest dengue caseloads in Asia — bite prevention is critical for all travelers.
Malaria in Indonesia
No Prophylaxis Needed
Bali, Java (Jakarta, Yogyakarta, Bromo), Lombok, Gili Islands, Sumatra (major cities) — no significant malaria risk. No antimalarial medication recommended for these destinations.
Malarone or Doxycycline Recommended
Papua, West Papua, Maluku islands, rural Nusa Tenggara (Flores, Komodo area, Sumbawa), rural Sulawesi, rural Kalimantan/Borneo — antimalarial prophylaxis is recommended. Use Malarone (daily) or Doxycycline (daily). Chloroquine resistance is widespread — do not use chloroquine.
Discuss with Your Doctor
Raja Ampat (Papua), Banda Islands (Maluku), Togean Islands (Sulawesi), remote Borneo — these high-profile ecotourism destinations are in malaria risk zones. Discuss prophylaxis with your travel doctor based on your specific itinerary, accommodation type, and season.
Komodo National Park (Flores region) lies within a malaria risk zone. Many travelers visit Komodo on liveaboard diving trips — sleeping on a boat does not eliminate mosquito exposure. Discuss malaria prophylaxis with your doctor if visiting Komodo, Flores, or sailing through the Lesser Sunda Islands. Any fever after return requires urgent medical evaluation.
Recommended Vaccines for Indonesia
No vaccinations are required for entry from the United States. The following are recommended — see your doctor at least 4–6 weeks before departure.
High risk from contaminated food and water. Strongly recommended for all travelers to Indonesia regardless of destination. Two-dose series.
Typhoid is endemic in Indonesia. Strongly recommended for all travelers — risk is present even in Bali's tourist restaurants. Drug-resistant strains are a growing concern in Southeast Asia.
Rabies is endemic in Indonesia — including Bali, which has experienced significant dog rabies outbreaks. Stray dogs are common throughout the archipelago. Pre-exposure vaccination is strongly recommended especially for children, outdoor adventurers, and those visiting remote areas where post-exposure treatment may be unavailable.
Japanese Encephalitis Vaccine
Recommended for travelers spending a month or more in rural areas, especially on Java, Bali (rural), Lombok, Nusa Tenggara, and other agricultural islands. Transmitted by Culex mosquitoes near rice paddies at dusk/dawn. Two-dose series required.
Recommended for those who may receive medical care, engage in water sports with injury risk, or stay for extended periods. Three-dose series.
MMR, Tdap, Polio Booster, Influenza, COVID-19
Ensure all routine vaccinations are fully current. An adult polio booster is recommended for all Southeast Asia travelers.
Healthcare System in Indonesia
Bali
Bali has several international-standard private hospitals catering to the large expat and tourist community — BIMC Hospital (Kuta and Nusa Dua), Siloam Bali, and Kasih Ibu Hospital are the most commonly used. English is widely spoken. Emergency care is available. Serious cases may still require evacuation to Denpasar or Singapore.
Jakarta & Major Cities
Jakarta's top private hospitals — Siloam, Pondok Indah, Medistra, Mochtar Riady Cancer Center — offer excellent care for routine and specialist conditions. Quality is comparable to regional standards. English-speaking physicians are available at private facilities. These are the best medical resources in Indonesia.
Remote Islands, Papua & Borneo
Healthcare in remote Indonesia is extremely limited. Papua, the Maluku islands, and remote Borneo/Kalimantan have minimal facilities. Air evacuation is frequently required — to Makassar, Manado, Surabaya, or Darwin (Australia). Medical evacuation insurance is non-negotiable for remote island travel. Singapore (approximately 90 minutes from Jakarta) is the regional medical hub.
Indonesia is the world's premier scuba diving destination. Decompression illness (DCS) is a real risk. Hyperbaric chambers are available in Bali (BIMC), Lombok, and a few other locations — but many popular dive destinations (Raja Ampat, Banda Sea) are very far from the nearest chamber. Consider DAN (Divers Alert Network) membership and ensure your dive insurance covers evacuation. Never dive within 12–18 hours of flying.

STEP Enrollment
Register at step.state.gov — especially important given Indonesia's natural disaster risks (earthquakes, tsunamis, volcanic eruptions).
Nature & Weather Risks
Volcanic Activity
Indonesia has over 130 active volcanoes — the most in the world. Mount Merapi (Java), Agung (Bali), Sinabung (Sumatra), and Anak Krakatau are frequently active. Eruptions can occur with little warning, causing ash clouds, pyroclastic flows, and flight disruptions. Monitor PVMBG (Indonesian volcano authority) alerts before any volcano visit. Always follow official exclusion zones.
Earthquakes & Tsunamis
Indonesia sits on the Pacific Ring of Fire — devastating earthquakes and tsunamis occur regularly (2004 Indian Ocean tsunami, 2018 Lombok and Sulawesi earthquakes). Know your accommodation's tsunami evacuation route if staying in coastal areas. After any significant earthquake near the coast, move to high ground immediately. Monitor BMKG (Indonesia's meteorological agency) alerts.
Ocean Currents & Diving Safety
Indonesia's waters include some of the strongest ocean currents in the world — particularly in the Komodo Strait, Alor, and many dive sites. Drowning is a significant risk for swimmers and divers who underestimate current strength. Dive only with experienced, licensed dive operators. Snorkelers should exercise extreme caution in areas with strong currents.
Wildlife Hazards
Indonesia's wildlife includes venomous snakes (king cobras, pit vipers), Komodo dragons (whose bite carries risk of infection), box jellyfish (extremely dangerous in some waters), stonefish, and blue-ringed octopus. Follow all wildlife encounter guidelines from guides. Never handle marine life. Seek immediate medical care for any wildlife injury.
Road Safety
Traffic accidents are a leading cause of tourist injury and death in Indonesia — particularly on Bali, where motorbike accidents involving tourists are extremely common. Always wear a helmet when riding a motorbike (mandatory and essential). Road rules are loosely enforced. Roads can be narrow, steep, and poorly lit. Use reputable drivers for longer journeys.
Forest Fires & Haze
Annual forest fires in Sumatra and Kalimantan (Borneo) produce severe haze that can affect respiratory health across the region, including Bali and Singapore. Travelers with asthma or respiratory conditions should monitor air quality indices (AQI) during July–October and carry adequate medication. N95 masks provide significant protection.
Crime, Violence & Safety Risks
Terrorism
Terrorist attacks have targeted Bali, Jakarta, and other major centers. Western interests, tourist hotspots, and crowded public areas remain potential targets. Remain alert in shopping areas, tourist sites, transport hubs, and hotels. Report suspicious packages or behavior immediately.
Petty Crime & Scams
Pickpocketing, bag snatching, and tourist scams are common in Bali and Jakarta. Common scams include gem fraud, unlicensed money changers offering inflated rates and short-changing, and fake tour operators. Use only licensed money changers (Authorized Money Changers) and reputable tour operators.
Drug Laws
Indonesia has some of the world's strictest drug laws — possession of even small amounts of narcotics can result in the death penalty. Several foreigners have been executed for drug offenses in Indonesia. Do not carry, purchase, or consume any illegal substances. Do not carry packages for others.
Papua Warning
Papua and West Papua (Level 3): Ongoing separatist conflict and armed clashes between security forces and armed groups. Foreigners have been killed and taken hostage. Travel requires special government permits and extensive security planning. The US Embassy strongly advises against non-essential travel.
Other Health Risks in Indonesia
Hyperendemic throughout Indonesia including Bali. Indonesia consistently records among Asia's highest dengue burdens. Daytime DEET repellent use is the primary prevention. Severe dengue can be fatal — seek medical care promptly for any high fever after mosquito exposure.
Very common throughout Indonesia. Drink only bottled or purified water. Even in Bali's upscale restaurants, food hygiene is variable. Carry ORS and a standby antibiotic. Be particularly cautious with ice, salads, and raw seafood outside reputable establishments.
Zika has been detected in Indonesia. Pregnant travelers or those planning pregnancy must consult their OB/GYN before travel. Use DEET repellent consistently. The same Aedes mosquito prevention measures cover dengue, Zika, and chikungunya simultaneously.
Bali Belly
"Bali belly" (traveler's diarrhea) is so common among visitors to Bali it has its own colloquial name. Even careful eaters are sometimes affected. Maintain strict water and food hygiene, wash hands frequently, and carry ORS. Most cases resolve within 24–48 hours with rehydration. Seek medical care for severe, bloody, or prolonged diarrhea.
