[Spread of infection with hepatitis B and C viruses in different population groups of north-western Ukraine].

The detection rate of specific markers of hepatitides B and C among the child and adult population, including 487 children in 5 boarding schools, 338 oncological, hematological, urological patients and 206 medical staff members in Rovno and the Rovno region (North-Western Ukraine), was determined. In boarding-school the markers of HB (HBsAg, anti-HBs, summary anti-HBc) were detected 3.5 times more often than among the child population in general (in 28.

[The risk of becoming infected with hepatitis B and C viruses in the pupils of children's boarding schools].

The risk of contamination of 487 inmates of 5 boarding schools at northwestern Ukraine with hepatitis B (HB) and hepatitis C (HC) viruses was analyzed and the role of some factors facilitating the spread of these infections among the inmates of such schools was shown. In 28.3 +/- 2.

[The current problems in the epidemiology and prevention of enteric viral hepatitis in Russia].

The presence of great differences in the activity of the epidemic process of hepatitis A (HA) in some regions of Russia is shown and the data necessary for establishing the structure of HA foci in groups of children, as well as the proportion of different forms of the disease registered in such foci (the icteric form in 22.7% of patients, the obliterated form in 11.3% of patients, the nonicteric form in 45.

[A trial of using immunoglobulins of known specificity for preventing hepatitis A in regions with high epidemic activity].

The economic effectiveness of immunoglobulin prophylaxis (IGP), carried out among children aged 1-3 at the beginning of a seasonal rise in hepatitis A (HA) morbidity with high coefficients of protection (80-85%), was directly related to the activity of the epidemic process. Preparations with sufficiently high content of antibodies to HA virus sharply decreased the manifestation of this infection. The detection rate of the manifest forms of the infection among children covered by prophylactic measures in the foci of HA was considerably lower than among children who had not received the preparation.
