Blood transfusion
A blood transfusion given elsewhere than in the British Isles, Central or South America or Africa prevents blood donation for at least four months. If you have had a blood transfusion in the British Isles, this prevents blood donation permanently (risk of variant Creutzfeldt-Jakob disease which is the human form of BSE or ‘mad cow disease’). Also, a blood transfusion given in Central or South America or Africa prevents blood donation permanently because of the risk of tropical diseases (trypanosomiasis infections in particular).
