As suggested by seroepidemiological studies, chlamydial infections also occur during childhood. Antibodies to C. trachomatis can be detected in sera from healthy children (Black et al., 1981; Grayston et al., 1982; San Joaquin et al., 1982; Gray et al., 1986) (Fig. 67). In some studies, antichlamydial antibodies were found more often in girls than boys, whereas in other series such antibodies were found equally often in both sexes. Frequently, after the disappearance of maternal antibodies, a slow age-related increase in the seropositivity rate, i.e., up to 7–12%, throughout childhood up to puberty has been found. Gray and co-workers (1986) found antibodies in boys to occur most often at the age of 7–8 years, whereas in girls the peak incidence occurred at puberty. The prevalence of antibody to C. trachomatis was similar in healthy children and children with respiratory complaints.
