Neonatal infection with hepatitis B virus carries a very high risk of resulting in a persistent infection.
Babies born to hepatitis B carrier mothers are at risk of infection through exposure to blood and body fluids during birth.
These'at risk'babies can only be identified through screening of all mothers during pregnancy.
Prevention of infection in this group is a key element in any nation's strategy to reduce the incidence and eventually eliminate hepatitis B inflection in its population as the persistently infected infants are a reservoir of infection throughout their lives.
The infected adult carries a relatively low risk of becoming a chronic carrier (<10%). Various strategies for screening in pregnancy have been adopted.
These include attempts to identify women with a history of'risk behaviour'testing only women who were born in areas of high endemicity, pooling of sera and universal antenatal screening.
The advantages and disadvantages of the various strategies will be discussed.
