Powdered or tinned milk is available and is recommended, but make sure that it is reconstituted with pure water. Avoid dairy products that 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.
Rabies is widespread, particularly in dogs and bats.
If you are bitten, seek medical advice without delay. For persons at high risk of exposure on a continuing basis, it may be advisable to have a course of rabies vaccine. Persons taking animals to El Salvador should be certain that the animals are immunised against rabies. An outbreak of dengue fever was reported in February 1998. Travellers should ask their doctor for advice before travelling.
