There is no reciprocal healthcare agreement between the UK and Bulgaria, so travellers to the country need to take out comprehensive medical insurance that provides for all treatment locally as well as evacuation from the country in the event that their condition cannot be treated locally.
While hospitals throughout the country are of a reasonable standard, many of the medical practices used in Bulgaria are old fashioned, and quaint by UK standards.
Outside of major cities, you should only drink bottled water because tap water can be contaminated.
