The UK and Bosnia and Herzegovina have a reciprocal healthcare agreement which entitles British passport holders to free hospital treatment and some dental treatment in Bosnia and Herzegovina. Although British nationals are entitled to free treatment, in practice the healthcare authorities in Bosnia might not have the immediate resources to provide treatment without charging. Medical and dental facilities, particularly outside Sarajevo and major towns are also limited.
The healthcare agreement will not cover you for any medical costs incurred through injuries sustained from undertaking dangerous sporting activities.
As with many countries in mainland Europe rabies is present within the animal population of Bosnia and Herzegovina. Whilst the incidence of rabies transferring to the human population is very rare you are advised not approach any wild animals or stray dogs.
You should exercise normal precautions to avoid exposure to HIV/AIDS.
