Health
Ireland has excellent health care system and facilities. For EU citizens, upon production of the European Health Insurance Card (EHIC), basic healthcare services are provided free. Other nationals are recommended to purchase health insurance for the time of their stay. Up-front payment for medical treatment is normally required. Some countries have reciprocal health care agreements (such as Australia) with Ireland that may ensure free emergency treatment, so you should check the details before you go.
Safety
Ireland has a low rate of serious, violent crimes.
Petty crime like bag snatching or pickpocketing is more common, particularly in crowded places frequently visited by tourists.
Car theft, mostly targeted on rental cars, is increasing. Car break-ins mostly happen in Dublin and travelers should be aware that some of insurance policies don’t cover losses from cars.
In general, Ireland is safer than most countries in Europe, but travelers should take common sense safety precautions.
