An outbreak of Ebola virus disease has been confirmed in Sierra Leone, Guinea and Liberia. If you travel to this region you should follow the health advice issued by the National Travel Health Network and Centre. There have been no confirmed cases of Ebola in Ghana. For further details about this outbreak of Ebola, see the World Health Organization website, the NaTHNaC outbreak surveillance database and this map showing the areas affected. Around 70,000 British nationals visit Ghana every year. While most visits are trouble-free, violent crime can occur at any time. Be particularly vigilant in public areas, and take care when travelling by road. Localised outbreaks of civil unrest can occur at short notice in the north of Ghana. Following sporadic gun violence which left one person dead, the Nanumba North District Security Council has imposed a 12-hour curfew in Bimbilla in the Northern region of Ghana. There is an underlying threat from terrorism.
