Abstract:
We studied the prevalence of IgG and IgM antibodies to the human herpesviruses in a hospital-based population of 181 individuals aged 0 to 25 years, who were resident in Vellore, south India or surrounding rural areas. Antibodies to the Epstein-Barr virus (EBV) viral capsid antigen were determined by indirect immunofluorescence, while antibodies to the remaining herpesviruses were determined by enzyme-linked immunosorbent assay. The age-specific prevalence rates of IgG antibodies to EBV and cytomegalovirus (CMV) rose rapidly after birth to reach a value of over 90% by the fourth year of life. High age-specific IgM prevalence rates and geometric mean titres (GMT) of IgG antibody in children 6 months to 2 years of age, and the early median age of virus infection (1.4 years for EBV and less than 1 year for CMV) indicate that primary infection with these viruses occurs early in life. In contrast, age-specific prevalence rates of IgG antibodies to varicella-zoster virus (VZV) and herpes simplex virus (HSV) rose gradually after birth to attain maximal values of only 72% (VZV) and 83% (HSV) in the 15-25 year age group, and the median ages of infection were delayed (12.25 years for VZV and 8.2 years for HSV). The age-specific IgG prevalence rates of VZV and HSV, and of EBV and HSV showed statistically significant positive correlations, suggesting that common epidemiological factors may underlie the pattern of infections due to these groups of viruses.(ABSTRACT TRUNCATED AT 250 WORDS)
