EHIC is a free card which gives access to state-provided healthcare during a temporary stay in any of the 28 EU countries as well as in Iceland, Liechtenstein, Norway and Switzerland. The card entitles holders to state-provided healthcare under the same conditions and at the same cost as citizens of that country. In some cases, but not all, treatment will be free.
Be aware though the EHIC is not an alternative to travel insurance as it does not cover private healthcare or return flights if you have to come home early for health reasons
Cards are issued by your national health insurance provider.
UK citizens can apply for the card for free by going here.
A leaflet about this is available electronically from the EU Bookshop or can be picked up from the EDC office in Taylor Library.
