title: Prevalence of rubella virus and cytomegalovirus infections in suspected cases of congenital infections.
abstract: Although rubella virus and cytomegalovirus (CMV) are important causes of congenital infections, information on their prevalence in our country is scarce. We studied a total of 249 infants suspected of having congenital infections from January 1988 to September 1989. Serum samples of these infants were tested for rubella and cytomegalovirus specific IgM antibodies by mucapture ELISA. Thirty (12%) infants were positive for rubella IgM antibody, and 50 (20%) had CMV specific IgM antibody. In the group presenting with hepatosplenomegaly (n = 56) rubella and CMV specific IgM antibodies were detected in 1 (1.7%) and 25 (44.6%) infants respectively. In the group presenting with congenital malformations (n = 90), 23 (25.5%) were positive for rubella, and only 9 (10%) had CMV IgM antibodies. Of the infants presenting with mental retardation (n = 39), only CMV infection was detected in 3 (7.7%) infants, whereas amongst the group showing intrauterine growth retardation (n = 16), 5 (31.25%) had CMV specific IgM antibodies and 2 (12.5%) had rubella specific IgM antibodies. In the miscellaneous group (n = 48), 4 (8.3%) and 8 (16.6%) infants had rubella and CMV IgM antibodies respectively. CMV infection was prevalent in a significantly higher number of children with hepatosplenomegaly than rubella while in infants with congenital malformations a significantly higher number had rubella infection. It is concluded that rubella and CMV infections are commonly seen in children with intrauterine infections in our population.
