Estimating Annual Births to Hepatitis B Surface Antigen–Positive Women in the United States by Using Data on Maternal Country of Birth

摘要

A national estimate of births to hepatitis B surface antigen (HBsAg)–positive women can help public health programs plan surveillance, educational, and outreach activities to improve identification and management of at-risk women and infants. Stratifying mothers by country of birth allows for the application of region-specific HBsAg prevalence estimates, which can more precisely estimate the number of at-risk infants. The objective of our study was to estimate the number of births to HBsAg-positive women in the United States with more granularity than previous models.
