Seroepidemiology of viral and toxoplasmal infections during pregnancy among Arab women of child-bearing age in Kuwait.

Five hundred and seventy three of 606 (94.6%), 583 of 604 (96.5%) and 575 of 595 (96.6%) women were found to have antibody to rubella virus, cytomegalovirus and herpes simplex virus, respectively. The Geometric Mean Titre (GMT) of haemagglutination-inhibition antibody to rubella virus was 60.97, while the GMT of complement-fixation antibody to cytomegalovirus and herpes simplex virus were 28.49 and 25.01, respectively. Furthermore, 301 of 517 (58.2%) women were also found to possess antibody to toxoplasma (GMT = 10.12) as detected by the passive-haemagglutination test. No significant differences in antibody prevalence or GMT could be found among the various nationalities studied except among Bedouins who showed a significantly higher rate and GMT of antibody to rubella virus and for the Mediterranean Arabs who showed significantly higher rate of immunity to and GMT of toxoplasma antibody when compared to other nationalities. Finally, no significant differences in antibody prevalence or GMT could be found among the various age groups.
