Food & drink
All water should be regarded as being potentially contaminated. Water used for drinking, brushing teeth or making ice should have first been boiled or otherwise sterilised. Milk is unpasteurised and should be boiled. Powdered or tinned milk is available and is advised, but make sure that it is reconstituted with pure water. Avoid dairy products which are likely to have been made from unboiled milk. Only eat well-cooked meat and fish, preferably served hot. Pork, salad and mayonnaise may carry increased risk. Vegetables should be cooked and fruit peeled.

Other risks
Hepatitis A, B and E are present; precautions should be taken. Since the beginning of 2006, Réunion has been affected by a serious epidemic of the mosquito-borne chikungunya virus, with a significant number of cases reported countrywide. Visitors should take precautions against being bitten by mosquitoes.
Rabies is present. For those at high risk, vaccination before arrival should be considered. If you are bitten, seek medical advice without delay. For more information, consult the Health appendix.

There are around 10 hospitals and many out-patient clinics. The French national health scheme is in force and there is a reciprocal health agreement with the UK (see France section). Facilities are limited and full health insurance is advised.
