The prevalence of parvovirus B19 infection among pregnant women of Ardabil in 2013

BACKGROUND AND OBJECTIVES Trans-placental transmission of parvovirus B19 during pregnancy can causes adverse outcomes. Regarding its importance in prenatal care, we decided to study prevalence of parvovirus B19 infection among pregnant woman in Ardabil, Iran. MATERIALS AND METHODS In a community based study with a cluster sampling, 350 pregnant women that attended in health care centers in Ardabil were selected. Serum samples were collected and Anti-B19 specific IgG was detected using commercial enzyme-linked immunosorbent assays (Euroimmune Elisa kit, Germany). Furthermore, a questionnaire filled for all participants during samples collection. RESULTS 64.6% (226/350) of participants were Ardabil citizen and the rest were from rural area (124/350). Anti-B19-specific IgG antibody was detected in 69.1% of pregnant women (242/350). Participants' ages ranged from 15 to 34 years with average of 23 years. According to our study, seroprevalence of IgG antibodies had positive significant correlation with the participants' age (r=0.268) but there were no significant relations between B19 seropositivity and living area, family member, number of commensals, number of living children, and the amount of hemoglobin (p>0.05). CONCLUSION Approximately, one-third of the participants were at risk of primary B19 infection. Therefore, health education of pregnant women and screening of infected pregnant women is recommended to prevent fetal complications.
