Travellers to Romania need to arrange comprehensive travel insurance before visiting the country, because there is no reciprocal healthcare agreement in place between the UK and the country.
Hospital standards away from the main cities can be very poor, and visitors should consider carrying a sterile medical kit including suture needles, syringes and dressings with them as there are often shortages in local hospitals. Most doctors will not speak English, although you can get a list of English Speaking doctors from the British Embassy in Bucharest.
Due to the risk of Hepatitis A in Romania, you should stick to bottled water to help minimise the risk.
Rabies is a major problem in Romania, and if you are visiting rural areas of the country, you should consider taking immunisation prior to travel.
You should avoid stray dogs in the country as some carry African Typhus, which is rather nasty, and is most dangerous in those with weaker immune systems such as the elderly.
