Among 530 consecutive patients hospitalized for acute hepatitis in the years 1986-1988 cytomegalovirus infection was diagnosed in 5 (0.9%). All 5 patients had symptomatic hepatitis with jaundice, 3 had pruritus. Hematological changes were relatively mild and liver function tests were not essentially different from those found in patients with hepatitis A, B, or non-A, non-B. All biochemical abnormalities returned to normal within 3-5 weeks.
