RESUMO
A hospital-based cross-sectional survey was conducted in Bhumibol Adulyadej Hospital between February and May 1997 to study the seroprevalence of cytomegalovirus (CMV) infection in hospitalized infants. Of 83 cases, 46 were boys and 37 girls, with the mean age of 11.87 months. The seroprevalence of CMV infection was 80.95, 61.90, 80.95 and 70.00% in infants at the age range of 0-6, 6-12, 12-18 and 18-24 months respectively. After excluding infants below 6 months of age, the seroprevalence rate was 70.97%. The family income of infants with positive CMV antibody was significantly lower than that of infants with negative results. There were no statistical correlations between seroconversion and age, sex, number of children in family and place of child rearing.
