[The incidence of occurrence of various types of viral hepatitis in Lublin district in 1993].

224 serum from patients (randomly selected from all patients hospitalized in 3 hospitals in Lublin district in 1993) in the early phase of acute viral hepatitis were tested by immunoenzymatic methods for presence of serologic markers of infections with HAV, HBV, HCV, CMV and EBV. The analysis of the results showed that 19.2% of patients were infected with HAV, 36.6% with HBV, 8% with HCV, 3.6% with CMV and 0.9% with EBV. The remaining 71 cases (31.7%) could apparently be attributed to the infection with HCV. These data showed that 80% of cases of hepatitis due to the parenteral spread of infections agents. We support the postulate that measures to prevent these infections should be strengthened.
