During an epidemic of erythema infectiosum in Norway 1984-86, infection with human parvovirus B19 was diagnosed in 22 pregnant women by detection of specific IgM antibodies. Information about the outcome of pregnancy was obtained in 19 cases. 17 women delivered live babies. In two cases, spontaneous abortion occurred in week 16 of the pregnancy. In 11 cases, cord blood and serum samples were obtained from the children at an age of between six and 15 months. No specific IgM antibodies were found in cord blood. Clinical information on 16 children at two years of age revealed normal growth and development in 15 cases. One child was hyperactive and showed delayed language development. B19 IgG antibodies were detected in three children with normal growth and development. According to our findings, there was no association between infection with human parvovirus B19 in pregnancy and congenital abnormalities.
