Greece health information and protections
No special vaccination is required for traveling in Greece and the Greek Islands. If you are under a special medical treatment, you are adviced to take these mecidines with you while traveling in Greece, as it is high possibility that you may not find the exact medicines there.
E111 free treatment for Europeans
The citizens of the European Union have right to the E111 document which offers access to free treatment in a Greek public hospital. Greek public hospitals are well equipped, at least in the major cities, but often overcrowded. The conditions and services of the private hospitals are much better but quite expensive. On the Greek islands and small towns, there are no hospitals but medical centres.
Food & Water
The Greek products are famous all around the world for their excellent quality. As for the water, in Athens and other large towns, tap water is drinkable. However, in most islands and in few mainland towns, bottled water is recommended. Most Greek islands do not have their own water, but water is brought by water tanks from the mainland, therefore it is used only for showering and house cleaning, not for drinking.
Serious health problems in Greece might come from the summer heat, especially in July and August which are the hottest months of the year. Heat may severly affect people with heart and lung problems and sensitive skin as well, especially considering that in summer temperature may rise to 40-43oC. To avoid problems in case of extreme heat, drink a lot of water, shower often, avoid physical activities, like walking, biking or climbing, wear light clothing and hat, avoid alcohol, wear sunglasses and sun lotion and generally avoid direct contact with the sun between midday and 4 o'clock in the evening.
