Development of children with early cytomegalovirus infection

Abstract

To find out whether cytomegalovirus (CMV) infection during the first months of life influences child development, developmental assessment at the age of 2 years was performed on 116 Finnish children chosen at random in a maternity hospital and followed from birth for the occurrence of CMV infection. Two of the children had congenital infection and 39 were infected after birth but before the age of 6 months. Another five children were infected between the ages of 6 and 12 months, and 70 remained non-infected. The developmental assessment, based principally on the Denver Development Screening Test (DDST), included 7 items for gross motor skills, 6 items for fine motor skills, and 4 items for language development. Significantly more perinatally infected children (7/39) were delayed in speech, compared with the non-infected children (3/70). Furthermore, some items assessing fine motor development were passed better by the non-infected than the perinatally infected children, but the difference in total score was not significant. The performance of the two children with congenital CMV infection did not differ from that of the non-infected children.
