The Foreign and Commonwealth Office (FCO) issues regularly-reviewed Travel Advice notices for 56 countries in Africa. The advice includes information on threats to personal safety arising from political unrest, conflicts, terrorist activities, anti-British demonstrations, lawlessness, violence, natural disasters, epidemics, and aircraft and shipping safety. FCO Travel Advice is reviewed for every country every month and following any significant incident. It is revised and reissued at least every three months. In a developing crisis FCO Travel Advice may be updated several times a day. The FCO website also contains important general information on safety abroad, under the heading 'Know Before You Go' and information on World Cup 2010 can be found there. There is also a link from the FCO Travel Advice for South Africa to that page. FCO Travel Advice is based on objective assessments of the risks to British nationals and is intended to give British nationals the information they need to make their own decisions about travelling to a particular country.
