Medical Summary
The health risk information presented here is summarized from Shoreland Travax®, a decision-support tool used by health care providers to perform a detailed health risk analysis based on specific locations, individual travel styles, and traveler risk behaviors. Travax provides practitioners current, independently researched malaria risk and prevention recommendations in a map-based format that goes beyond the annual WHO and US CDC statements included here. Not included here are current reports from Travax of disease outbreaks or environmental events that may pose elevated risks to travelers’ health and safety. The Providers section of this site offers a directory of health care providers who utilize Shoreland Travax for travel health counseling.

General Information
Indonesia is a developing nation classified as lower middle income. Located in Southeast Asia between the Indian Ocean and the Pacific Ocean, the climate classifications range from humid equatorial (no dry season) to humid equatorial (long dry season).
Vaccinations
Routine vaccinations are essential due to a persistent rise of vaccine-preventable diseases (especially markedly high rates of diphtheria, pertussis, and measles) globally. Prior to travel, travelers should be up-to-date with the age-appropriate routine vaccinations recommended by their home country, which may include: COVID-19; H. influenzae type B (Hib); hepatitis A; hepatitis B; herpes zoster; human papillomavirus; influenza; measles, mumps, rubella; meningococcal; pneumococcal; polio; rotavirus; tetanus, diphtheria, pertussis (Tdap preferred; consider an early pertussis booster for high-risk travelers); varicella.
Yellow Fever
See also: Library article for Yellow Fever
Although yellow fever does not occur in Indonesia, an official yellow fever vaccination certificate may be required depending on your itinerary.
- Requirement: A certificate proving yellow fever vaccination is required for travelers aged ≥ 9 months coming from countries with risk of YF transmission. This does not apply to airport transit stops (no exit through immigration checkpoint) in risk countries.
Other Vaccines
Depending on your itinerary, your personal risk factors, and the length of your visit, your health care provider may offer you vaccination against chikungunya, Japanese encephalitis, mpox, rabies, typhoid fever, or a one time polio booster if you haven't previously received one for travel.
Malaria

The following is current information as reported by the World Health Organization (WHO) and the US Centers for Disease Control (CDC):
WHO—International Travel and Health (current online update, Country List)
(2018) Malaria risk exists throughout the year in most areas of the five eastern provinces of East Nusa Tenggara, Maluku, North Maluku, Papua and West Papua. In other parts of the country, there is Malaria risk in some districts, except in Jakarta municipality, in cities and urban areas, and in the areas of the main tourist resorts. P. vivax resistance to chloroquine has been reported. Human P. knowlesi infection has been reported in the province of Kalimantan.- Recommended prevention in risk areas: C – Risk of P. falciparum malaria, in combination with reported chloroquine and sulfadoxine–pyrimethamine resistance. Mosquito bite prevention plus atovaquone–proguanil or doxycycline or mefloquine chemoprophylaxis (select according to reported side effects and contraindications) a
aAlternatively, for travel to rural areas with low risk of malaria infection, mosquito bite prevention can be combined with stand–by emergency treatment (SBET).
WHO Country List footnote: When available, the date of the most recent update or confirmation is indicated in parentheses in the country list. If no date is indicated, the most recent update or confirmation was provided before 2013.
CDC—Health Information for International Travel (current online edition)
Areas with malaria: All areas of eastern Indonesia (provinces of Maluku, Maluku Utara, Nusa Tenggara Timur, Papua, and Papua Barat), including the town of Labuan Bajo and Komodo Islands in the Nusa Tenggara region. Rural areas of Kalimantan (Borneo), Nusa Tenggara Barat (includes the island of Lombok), Sulawesi, and Sumatra. Low transmission in rural areas of Java, including Pangandaran, Sukalumi, and Ujung Kulong. None in cities of Jakarta and Ubud, resort areas of Bali and Java, and Gili Islands and the Thousand Islands (Pulau Seribu).- Drug resistance3 : Chloroquine (P. falciparum and P. vivax).
- Malaria species: P. falciparum 57%, P. vivax. 43%, P. malariae, P. knowlesi, P. ovale rare.
- Recommended chemoprophylaxis: Atovaquone-proguanil, doxycycline, mefloquine, or tafenoquine.4
3 Refers to P. falciparum malaria unless otherwise noted.
4 Primaquine and tafenoquine can cause hemolytic anemia in people with G6PD deficiency. Patients must be screened for G6PD deficiency before starting primaquine or tafenoquine. See Tafenoquine Approved for Malaria Prophylaxis and Treatment for more information.
Other Concerns
Travelers' Diarrhea
See also: Library article for Travelers' Diarrhea
High risk exists throughout the country, with moderate risk in deluxe accommodations. Community sanitation and food safety measures are generally inadequate. Some itineraries (e.g., remote destinations, austere accommodations) and activities (e.g., ecotourism, eating street or local-market food) further increase risk.
Travelers should observe food and beverage precautions, which reduce the likelihood of illness.
Travelers should carry loperamide for self-treatment of diarrhea and, if risk is moderate to high, an antibiotic to add if diarrhea is severe. Consult a knowledgeable health care provider regarding which antibiotic is appropriate for you and most effective for your destination.
Other Food-Borne Illnesses
Precautions to prevent brucellosis, seafood poisoning may be needed.
Insect- and Arthropod-Borne Diseases
Dengue, murine typhus, scrub typhus, West Nile virus, Zika may pose a risk. Personal protective measures are important.
Other Disease and Health Risks
Additional concerns include air pollution, anthrax disease, helminths, leptospirosis, marine hazards, melioidosis, monkey bites, Nipah virus, plague, schistosomiasis, sexually transmitted infections, snakebites, tuberculosis.
