The authors revealed by means of the haemagglutination-inhibition test (HIT) and the plaque reduction neutralization test (PRNT) that in 1983 to 1985 pregnant women in the Breclav district became infected with the Tahyna virus. HI antibodies against the virus were detected in 96 (28.4%) women from a total of 338 examined. A new infection was proved in 15 (4.4%) women. The majority of infections was contracted in August to October. Positive results were supported by the PRNT. Antibodies against arboviruses Sindbis, Calovo, West Nile, tick-borne encephalitis, Bhandza were not detected in any of the women.
