Yellow fever entry rule

Indonesia requires a yellow fever vaccination certificate from travelers arriving from (or who have transited through) a country with risk of yellow fever transmission. There is no yellow fever risk within Indonesia itself, and direct travel from Switzerland is not affected.

Vaccines

VaccineRecommendationReference
Routine vaccines

Make sure you are up-to-date on all routine vaccines before every trip — per the Swiss BAG schedule. These include:

BAG Impfplan
Chikungunya

Vaccination indicated during chikungunya outbreaks; may also be considered for countries with elevated risk (see EKRM statement).

—
Dengue

Qdenga® vaccination currently recommended only for travelers with documented prior dengue infection who will be exposed in a region with high dengue transmission.

—
Hepatitis A

Recommended for all travelers to tropical and subtropical countries. Note for Swiss travelers: Hepatitis A is not part of the routine Swiss BAG childhood schedule, so most adult travelers will need vaccination.

CDC Yellow Book
Hepatitis B

Consider per individual risk and stay duration. Routine in the Swiss childhood schedule since 1998 — younger travelers usually covered.

CDC Yellow Book
Japanese encephalitis

Consider for travelers spending a month or more in rural rice-growing or pig-farming areas, or with uncertain rural itineraries. Not needed for typical urban or beach-resort stays.

—
Rabies

Particularly recommended for: long stays; high individual risk regardless of duration (cycling/motorbike trips, hiking in remote areas, infants and children, those working with animals, cavers — bats!). Rabies is endemic in dogs and macaques across much of Indonesia, with notable activity in Bali and West Timor; post-exposure care can be difficult to access on smaller islands.

CDC Yellow Book
Typhoid

Recommended for long-term travelers, visiting friends and relatives, those staying in poor hygienic conditions, or with individual risk factors — especially for travel to smaller cities and rural areas.

CDC Yellow Book

Disease-specific guidance

Malaria

High

Risk varies dramatically by region. High transmission throughout Papua and West Papua, and across the eastern provinces (Maluku, North Maluku, East Nusa Tenggara). Risk is also present in rural Kalimantan, West Nusa Tenggara, Sulawesi, and Sumatra, with low transmission in some rural parts of Java. The main tourist areas — Jakarta, Bali resort areas, Ubud, and the Gili and Thousand Islands — are essentially no-risk. Chemoprophylaxis is recommended for travel to Papua and the eastern high-risk provinces.

High risk
Papua, West Papua, eastern provinces (Maluku, NTT)
Some risk
Rural Kalimantan, Sulawesi, Sumatra, NTB, parts of Java
No risk
Jakarta, Bali resorts, Ubud, Gili & Thousand Islands
Species
P. falciparum and P. vivax predominate
Prevention
Prophylaxis for Papua/eastern provinces; bite protection elsewhere
Malaria risk areas in Indonesia (CDC).

Yellow fever

None

No yellow fever risk in Indonesia. A vaccination certificate is required only for travelers arriving from, or transiting through, a country with yellow fever transmission risk. Direct travel from Switzerland is not affected.

Dengue

High

Endemic year-round throughout Indonesia, including Bali and all major tourist destinations, with peaks during and after the rainy season. Daytime mosquito-bite prevention is the main protection.

Distribution
Nationwide, incl. Bali and all major islands
Season
Year-round; peaks in/after rainy season
Mosquito
Aedes aegypti — bites during daytime

Chikungunya

Moderate

Transmission occurs with periodic outbreaks across Indonesia. The same daytime Aedes mosquito vector as dengue, so dengue prevention also protects against chikungunya. Vaccination considered in outbreak settings or for some longer stays (see EKRM statement).

General prevention

Food & water

Use bottled or filtered water, avoid ice from unverified sources, and pay attention to food hygiene. Standard tropical precautions reduce the risk of traveler's diarrhea, hepatitis A, and typhoid — particularly relevant when eating outside major hotels and resorts, including the well-known 'Bali belly'.

Mosquito protection

Dengue circulates year-round across the archipelago including Bali and other tourist destinations, so daytime mosquito protection (DEET or picaridin repellent, long sleeves) is essential everywhere. For travel to Papua, the eastern provinces, or rural Kalimantan/Sulawesi/Sumatra, protect at dawn and dusk as well for malaria, and discuss chemoprophylaxis with a travel medicine specialist before departure.
