If you're an EU citizen, a European Health Insurance Card (EHIC) covers you for most medical care but not emergency repatriation or nonemergencies. Citizens from other countries should find out if there is a reciprocal arrangement for free medical care between their country and Greece. If you do need health insurance, make sure you get a policy that covers you for the worst possible scenario, such as an accident requiring an emergency flight home. Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures.

It is important to be up-to-date with routine vaccinations, however Greece requires no additional vaccines.
Tap water is drinkable and safe in much of Greece but not always in small villages and on some of the islands. Always ask locally if the water is safe and, if in doubt, drink boiled or bought water. Even when water is safe, the substances and bacteria in it may be different from those you are used to and can cause vomiting or diarrhoea. Bottled water is widely available.
Although medical training is of a high standard in Greece, the public health service is badly underfunded. Hospitals can be overcrowded, hygiene is not always what it should be, and relatives are expected to bring in food for the patient – which can be a problem for a tourist. Conditions and treatment are much better in private hospitals, which are expensive. All this means that a good health-insurance policy is essential.
