[Prevalence of hepatitis B virus in women of childbearing age in Mali]. / Prévalence du virus de l'hépatite B chez les femmes en age de procréer au Mali.

ABSTRACT

A serological investigation on adult female in Mali show a high degree of positivity of hepatitis B virus (HBV) markers, of which 42% HBs Ag +. Only 6% exhibit active replication. The low prevalence of anti-HBs (+) with a high degree of anti-HB (+) explain a high incidence of infection with a low immune response to HBs antigen. The existence of anti-Delta (+) asymptomatic carriers is an additional support to a vaccination programme.
