[Results of a survey on post-transfusional malaria in France between 1960 and 1974].

This inquire demonstrated that transfusion malaria was not so rare as we thought. So 56 cases have been numbered between 1960 and 1974, and probably they do not reflect exactly the real situation. In our country, plasmodium falciparum, specifically responsible of the most serious accidents, is the form most frequently incriminated and its frequency increases among the years: 76,1% of the infects between 1970 and 1974. At last we have confirmed that a prevent of those accidents must consider as a subject any one having resided in an impaluded country, and that implies a constant knowledge of the epidemiologic map of this parisitism. This prevent will be increased so that the transfusion malaria will not get a illness disease in France.
