Serosurvey of parvovirus B19 and cytomegalovirus infections among female university students in Shiraz, Southern Iran.

Infection with parvovirus B19 and cytomegalovirus (CMV) during pregnancy might lead to fetal infection, resulting in congenital abnormalities. This study aimed to investigate the frequency of IgM and IgG antibodies against parvovirus B19 and CMV in female university students in Shiraz, in Fars province, Southern Iran. In this cross-sectional study, 370 female university students were included. Blood samples were collected from each participant and tested for anti-parvovirus B19 and CMV IgG and IgM antibodies, using commercial ELISA kits. The mean age of the participants was 24 (±7)years. Out of 370 participants, 327 (88.4%) and 9 (2.4%) were positive for IgG and IgM antibodies against CMV. Moreover, 211 (57.0%) and 4 (1.1%) of the participants were respectively positive for IgG and IgM antibodies against parvovirus B19. The difference in CMV or parvovirus B19 seropositivity between different age groups was not statistically significant (P>0.05). The findings of our study showed that more than 50% of the female university students are seropositive to CMV and parvovirus B19 infections. It highlights the importance of health education and also the laboratory screening of females at childbearing age to reduce the risk of congenital infections resulting from these viral infections.
