The standard of local medical care can be poor and some medical tests can’t be done reliably. Psychological and psychiatric services are also limited throughout Indonesia.
Good medical care can be very expensive and in remote areas attention for serious injuries or illness is likely to be unavailable. You may require expensive medical evacuation costing up to tens of thousands of pounds. Make sure you have adequate travel health insurance and accessible funds to cover the cost of any medical treatment abroad and repatriation.

Ash plumes from volcanoes can affect air quality and have an impact on health, particularly for anyone with pre-existing respiratory conditions. If you’re in the vicinity of a volcanic eruption and affected by subsequent ash fall, you can find further information in digital pamphlets issued by the International Volcanic Health Hazard Network (IVHHN), which cover the potential health hazards of volcanic ash and offer advice on how to prepare and cope with ash fall.
During the dry season (May-November), widespread forest fires can cause smoke haze resulting in poor air quality across parts of Indonesia, particularly Riau Islands, central Sumatra and Kalimantan. The haze can cause disruption to local and regional air travel, and the air pollution may have an impact on public health. Keep up to date with local information and seek medical advice on appropriate precautions. A regional haze map is available from the Singapore Meteorological Service.

Avian Influenza (bird flu)
Avian flu has led to over 150 confirmed human fatalities in Indonesia since 2003, although the annual rate appears to be declining. All cases so far have been linked to close contact with poultry.
Although the risk to humans from Avian Influenza is low, you should avoid visiting live animal markets, poultry farms and other places where you may come into close contact with domestic, caged or wild birds, and make sure poultry and egg dishes are thoroughly cooked.
