Prevalence of herpes simplex types 1 and 2, varicella zoster virus, cytomegalovirus, and immunoglobulin G antibodies among female university students in Syria

ABSTRACT

To examine the current seroepidemiology of immunoglobulin [Ig]G for herpes simplex virus types 1 and 2 [HSV 1-2], varicella zoster virus [VZV], and cytomegalovirus [CMV] among university females of childbearing age in Syria. A cross-sectional study was conducted to examine the female students of the Pharmacy College, Kalamoon University, Deratiah, Syria, where 316 sera were collected from October 2009 to November 2010, and subjected to HSV 1-2, VZV, and CMV IgG screening and titration using enzyme-linked immunosorbent assay-based techniques in the Microbiology Laboratory. A total of 164 participants were positive for HSV 1-2 IgG giving a prevalence of 52%, leaving a relatively high proportion of susceptibility among the tested group. For VZV, 91% of the participants [n=287] were positive for its specific IgG, while, regarding CMV, 74.5% [n=235] were positive, and 25.5% were negative for CMV specific IgG. Although most participants were seropositive for herpes viruses IgG, suggesting a natural virus circulation within the community, screening for protective immunity is suggested against HSV, since a relatively high proportion of tested females are still susceptible. In addition, and because of its nasty outcomes during pregnancy, IgG against CMV should also be tested. High percentage of positivity towards VZV could be explained due to introduction of the new vaccine program, and therefore, further analysis during pregnancy is not recommended
