The medical facilities in Iceland are good and available free to European Union citizens with a valid E-111 form or its replacement ID card. Scandinavian citizens must show valid passport and medical insurance to be treated.

Infectious diseases aren't a problem in Iceland. Inoculations aren't required except if you are arriving from countries that suffer from infectious diseases like cholera.

The biggest threat to your health is likely to be accidental injury or bad weather. Always make sure you have more than adequately warm and waterproof clothing. Selection of appropriate clothing is especially important in Iceland and can even be a matter of life and death. The most known Icelandic outdoor wear brand is 66°North (the latitude of the Arctic circle) which has been tried and tested by Icelanders in rough conditions for 80 years. Exercise extra caution in geothermal areas.
