Abstract

Sera of patients suffering from acute hepatitis, and different forms of chronic hepatitis were found to be reactive to reagents prepared from the yellow fever virus (YF) vaccine strain. Serum samples of 1974 patients were tested, and 133 of them were positive. Hepatitis C virus specific antibodies were absent from the majority of them. The frequency of antibodies to other flaviviruses (tick-borne encephalitis, West Nile) and hepatitis B virus markers was similar to that measured among the population in Hungary positive for any of the surrogate markers of hepatitis infections. Results of both immunofluorescence tests, and Western blots suggest that there is a non-A, non-B, non-C hepatitis virus circulating among the Hungarian population, which possesses antigenic cross-reactivity with the yellow fever virus, but the identity to any of the known flaviviruses could not be verified yet. No history of yellow fever vaccination could be revealed in any of the patients included into this study. The anamnestic data on previous transfusions or surgical operations can be verified only in the case of the half of YFV-positive patients, nevertheless, the sexual transmission seems to be very infrequent. Attempts are continued in order to detect the viral RNA using polymerase chain reaction, and clone cDNA sequences for sequence analysis.
