Anti-hantavirus antibodies in human sera in Czechoslovakia.
By indirect immunofluorescence using antigens of hantavirus Hantaan and CG 18-20 on Vero E6 cells were examined 5,827 samples of sera from 5,299 probands of Czechoslovakia. In 49 persons (0.94%) were found antibodies of titres 1:32 and higher. Two groups of elderly farm workers showed a cluster of positive individuals amounting to 9.9% and 29.4% respectively. The ratio of positivities in some other, randomly and specifically selected groups was deep below 1%. The partial results for the group of farmers were confirmed by RIA test. Occasionally antibodies only to one of the hantavirus serotypes, at other time, to both were found. The authors discuss the findings of antibodies of the two serotypes in humans as related to the evidenced existence of two hantavirus antigen serotypes in animals.
