title: [Status of collective immunity to hepatitis A virus in urban residents in Byelorussia].
abstract: The large immune stratum and intense collective immunity to virus hepatitis A among the urban population of Byelorussia are characteristic of hyperendemic territory. The geometric mean of the antibody titer has been noted to increase with age, which is probably due to repeated infections of persons who have already had the disease. The use of this value for the characterization of collective immunity and epidemiological situation has been proposed.
