It is advisable to get a complete health check done before visiting Indonesia. Also, vaccinations against cholera, hepatitis A, typhoid, Japanese encephalitis and dengue are recommended. A yellow fever certificate is necessary for those travelling from an infected area.

The risk of malaria is high; carry proper anti-malarial and antibiotic medication, albeit in their original package along with the prescription. Drink only bottled water and avoid contact with live poultry.

Social unrest in parts of Indonesia is a cause of concern. Since the Bali bomb blasts of 2005, a high risk of danger for visitors exists. Ache, in particular, is prone to violence, as is the Sulawesi region. It is advisable to check on the latest situation and the warnings issued before planning an itinerary.
