There is no reciprocal healthcare agreement between the UK and Albania, 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.
Hospitals in the country are of a low standard in comparison to the rest of Europe, and you should avoid having dental problems in Albania if at all possible, as the locals are nothing short of butchers with an a'level and a drill.
Keep to bottled water and UHT milk rather than taking the risk of cholera that you contend with from a tap.
