title: Epidemiology of herpes simplex virus in children by detection of specific antibodies in saliva.
abstract: OBJECTIVE
  To facilitate the study of the prevalence of herpes simplex virus (HSV) infection and its determinants in children, we developed a noninvasive saliva test.
  
  
  METHODS
  A capture enzyme-linked immunosorbent assay (ELISA) for the detection of IgG to HSV in saliva was developed, validated against a commercial serum ELISA in 110 children and 187 adults and used in a cross-sectional population-based study including 2,048 children ages 1 to 17 years, recruited in day-care centers and schools of Geneva, Switzerland. Demographic and socioeconomic determinants of HSV prevalence were studied.
  
  
  RESULTS
  The sensitivity and specificity of the saliva assay were 94.1 and 95.5%, respectively, compared with the commercial serum ELISA. Participation in the cross-sectional study was 86.6%. The overall prevalence of anti-HSV IgG was 23.91%. It increased with age up to 7 years, reaching a plateau at 35% without evidence for day-care or school transmission. The main determinants of prevalence were region of national origin and parents' professional category.
  
  
  CONCLUSIONS
  This new saliva-based assay proved its feasibility in the first population-based study of HSV prevalence in children that uses saliva, confirmed its validity by identifying determinants of prevalence consistent with previous reports and yielded new information, such as the lack of influence of day-care attendance, in the population studied.
