Abstract
Aim. Determination of prevalence of markers of hepatitis A and E among migrant workers, who had recently arrived in Russian Federation from countries with various degree of endemicity regarding this infection. Materials and methods. Sera samples from 1333 migrant workers, who had recently arrived in Russian Federation from Uzbekistan (n=464), Tadzhikistan (n=415), Ukraine |n=308) and Moldova (n=146) were studied. Anti-HAV IgG, anti-HEV IgM and IgG were determined using commercial ELISA tests. HEV RNA was determined in samples positive for anti-HEV IgM by RT-PCR with degenerate primers to HEV genome sequence coding capsid protein. Anti-HEV IgG were detected significantly more frequently among migrants from Uzbekistan and Tajikistan compared with migrants from the Ukraine and Moldova (25,4 and 43,1% versus 7,8 and 12,3%, respectively, p
