In the period of reduced incidence of viral hepatitis in Tajikistan, January-December, 1990, 1562 patients with acute viral hepatitis (AVH) were examined in the first days of the jaundice phase (928 children under 14 years and 634 adults) in Dushanbe. Markers of hepatitis A, B, and D (HBsAg, anti-HA IgM, anti-HBc IgM, anti-delta IgM) were determined by enzyme immunoassay. Hepatitis A occurred in 25.8% of the patients with AVH, mostly children of 1-6 years, HB in 22.8%, HD co- and superinfection) in 9.2%. In 42.1% of the patients who had no HA, HB, or HD markers in the blood, non-A, non-B hepatitis (mostly hepatitis E) was diagnosed, mainly in the age groups of 30-39 years (70.7%) and 15-29 years (59.2%). Thus, in Tajikistan hepatitis E occurs not only during outbreaks of this infection but also sporadically.
