Before travelling to Hungary or to another EU country for a short stay - whether on holiday, a business trip or studies - you should get a European Health Insurance Card from your statutory health insurer. This will enable you to get any health care you might need during your trip.
The European Health Insurance Card proves your entitlement to health care. It is the physical proof that you are insured in an EU country.
If you fall unexpectedly sick during a temporary stay abroad, the European Health Insurance Card gives you the same right to statutory health care as people insured in the country you are in, so you can visit a local doctor.
