The chronic viral hepatitis B is a public health problem
and remains a global challenge with 350 million carriers of HBs antigen
(HBsAg). The prevalence of HBsAg varies from one country or continent to another.
In France, it is estimated to be 0.5%. In Morocco, the data are rare but some
studies have estimated the prevalence to be 2.5%. Our aim is to estimate the
prevalence of HBsAg among women who have recently given birth at the maternity
CHU Hassan II of Morocco Fez, and to describe the epidemiological profile and
risk factors for infection. In pregnancy, infection with hepatitis B virus
(HBV) is dominated by the risk of mother to child transmission (vertical
transmission), which can be avoided by serovaccination of the newborn. The
search for HBsAg should be performed in all pregnant women.
