[Treatment of Argentine hemorrhagic fever with convalescent's plasma. 4433 cases].
During the 23 consecutive annual epidemics of Argentine haemorrhagic fever observed from 1959 to 1983, a group of 4,433 patients were treated at Junin (Argentina) with convalescent's plasma; the overall mortality rate was 3.29%. In 1958, before convalescent's plasma was used, the mortality rate in 448 patients who received the conventional treatment was 42.85%. The difference between the two groups is highly significant and demonstrates the value of convalescent's plasma in the treatment of the disease.
