A yellow fever vaccination certificate is required of travellers over six months of age arriving from infected areas. Travellers arriving from non-endemic zones should note that vaccination is strongly recommended for travel to areas within the Amazon Basin, even if an outbreak has not been reported and they would normally not require a vaccination certificate to enter the country. All health centres, which are controlled by the Ministry of Health, will provide free information and medication to anyone entering a high risk area.
Pasteurised milk is widely available.
Avoid dairy products that are likely to have been made from unboiled milk. Avoid street food vendors and the cheaper restaurants. 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.
