Rationale

This metric shows the proportion of eligible infants testing positive for surface antigen (HBsAg). in England. This metric helps to monitor the effectiveness of measures to prevent mother-to-child transmission of hepatitis B.

Results may be affected by incomplete testing or follow up. Small numbers can lead to differences between years.
