Health, Vaccines & Medical Care in Bali

Bali is a safe destination health-wise by developing-world standards, but it is not without risk. Hepatitis A, typhoid, and Bali belly (traveller's diarrhoea) are the most commonly encountered issues. Rabies, dengue, and mosquito-borne diseases are present. This guide covers what vaccinations are recommended, how to avoid the most common illness, and what medical facilities are available if you need them.

Recommended Vaccinations

Routine Vaccines (Always)

• Hepatitis A: Strongly recommended for all travellers. Transmitted through contaminated food and water — common in Bali, particularly in street food. Two doses provide 20+ years protection. Get before travel.
• Typhoid: Recommended for most travellers, essential for stays over 2 weeks or adventurous eating. Injection (Vi polysaccharide vaccine) or oral vaccine available. Effective for 2–3 years.
• Tetanus/Diphtheria/Pertussis: Standard travel requirement, especially if you plan outdoor activities.
• Hepatitis B: Recommended if you may need medical treatment, tattooing, or any procedure involving needles. Already in childhood schedules in most Western countries.

Situation-Dependent Vaccines

• Rabies: Recommended for children, trekkers, those staying over 3 weeks, and anyone likely to interact with animals. Bali has a documented rabies problem — stray dogs and temple monkeys. Three pre-exposure doses over 21+ days. Get before travel; the post-exposure protocol is significantly simpler if you've had pre-exposure vaccination.
• Japanese Encephalitis: Consider for stays over 30 days in rural/agricultural areas or during rainy season when mosquito density peaks. Two doses 28 days apart.
• Malaria: Bali itself is very low risk — the main tourist areas (Kuta, Seminyak, Ubud, the Bukit Peninsula) have no malaria transmission. Malaria prophylaxis is NOT routinely recommended for Bali.

Bali Belly (Traveller's Diarrhoea)

The most common health complaint among Bali tourists. Usually caused by bacterial contamination (E. coli, Salmonella, Campylobacter) in food or water. Typical onset: 6–24 hours after exposure. Most cases are mild and resolve in 24–48 hours without treatment.

Prevention

• Never drink tap water — all drinking water must be bottled or filtered
• Be cautious with ice at warungs (beach clubs and hotel ice are typically from filtered water; warung ice may not be)
• Raw vegetables at tourist restaurants are often washed in tap water — a real risk in lower-tier establishments
• Eat cooked food hot; avoid room-temperature buffets that have been sitting out
• Peel fruit yourself rather than buying pre-cut
• Wash hands before eating — soap and water is better than sanitiser for norovirus

Treatment

• Mild diarrhoea without fever: oral rehydration salts (ORS) from any pharmacy, IDR 5,000–10,000 per sachet, rest, continue eating small amounts
• Moderate: bismuth subsalicylate (Pepto-Bismol equivalent) or loperamide for symptomatic relief
• Severe or with high fever: azithromycin or ciprofloxacin (available over-counter in Bali pharmacies) — consult a doctor before self-treating with antibiotics
• See a doctor: if symptoms last over 3 days, if blood appears, if fever over 39°C, if dehydration is significant (dizziness, no urination)

Dengue Fever

Dengue is transmitted by Aedes mosquitoes that are active during daytime. Present throughout Bali; peak risk during and after the rainy season. There is no specific treatment — supportive care only. Prevention:

• DEET-based insect repellent (30–50% DEET) applied during daytime outdoors
• Light-coloured long sleeves and trousers if in jungle or rice field areas during the day
• Air-conditioned rooms with windows closed are lower risk
• Dengue symptoms: sudden high fever, severe headache (behind the eyes), joint/muscle pain, rash (appears 2–5 days after fever starts). Seek medical attention immediately.

Medical Facilities in Bali

• BIMC Hospital Kuta (Jl. Bypass Ngurah Rai): The standard recommendation for tourists. 24-hour emergency, international-standard facilities, English-speaking staff. Consultation IDR 500,000–900,000. Accepts most travel insurance directly.
• SOS Medika Clinic Seminyak (Jl. Sunset Road): International clinic for non-emergencies. 24-hour. Good for Bali belly, infections, wound treatment.
• BIMC Nusa Dua: Second BIMC location, good for tourists in the resort area.
• Sanglah General Hospital (Denpasar): The main Indonesian government hospital. Cheapest option. English limited; quality adequate for many conditions. Not recommended as first choice for tourists unless BIMC/SOS are unreachable.
• Ubud area: Ubud has several small clinics for minor issues; serious cases should go to BIMC Kuta (40 minutes).

Travel Insurance

Travel insurance that includes medical evacuation coverage is strongly recommended for Bali. BIMC can handle most conditions, but serious trauma (motorcycle accident, major illness) may require evacuation to Singapore or Australia. Medical evacuation costs USD 30,000–80,000 without insurance. Annual multi-trip travel insurance with medical coverage (World Nomads, SafetyWing) typically costs USD 100–200/year and is standard among long-term travellers.
