Prevalence of HBsAg and HCV antibodies in a cohort of pregnant women: the continuous survey as public health tool against pregnant and neonatal complications.

Pregnancy is a very delicate condition and different external factors can alter fetal development. Microorganisms are surely the principal ones. Several studies have shown that HBV and HCV infections could have an impact on pregnancy outcome. We performed a survey of blood samples from pregnant women in order to evaluate the presence of HBsAg and HCV antibodies. 6,896 women were tested from 2016 to 2019. 0.2% of the women in the Italian group and 2.1% among the foreigners tested positive for HBsAg, while 0.2% among the Italians and 0.7% among the foreigners were positive for HCV antibodies. Moreover, an increasing trend for both infections was observed in the foreigners. The results showed that in Italian women the positivity rates for HBV and HCV infections are very low despite the presence of both infections. A different consideration must be made for the foreigners, in whom we observed a higher positivity rate for both infections. Our findings stress the importance of a continuous surveillance of HBV and HCV markers during pregnancy and suggest that there is still much to be done in order to reduce the risk of these infections in this delicate period of a woman's life.
