RESUMEN
An outbreak of viral hepatitis B at a sugar refinery in the Ukraine was verified by the detection of HBs antigens and IgM antibodies to hepatitis A virus in the radioimmunoassay. Cases of hepatitis E among workers, employed mainly in heat-treatment departments, appeared due to mass contamination of water mains with sewage water from the residential zone in the presence of a few cases of the disease.

The study has revealed that the concentration of HBsAg preparations is simple and easily performed with the use of polyacrylamide, but not dextran gels. Rheophoresis has been shown to be a more sensitive method of indication than countercurrent immunoelectrophoresis. Rheophoresis has been proposed for introduction into medical practice at rural health institutions.

The use of Alsever's solution has abolished the necessity for taking intravenous blood and made it possible to divide the determination of HBsAg and antibodies to this antigen into two stages. The combined determination of HBsAg and its antibodies by the third-generation techniques improves the quality of the epidemiological survey of hepatitis B cases and the epidemiological observation of risk groups.
