Hepatitis B virus infection among pregnant women in northeastern Romania.

We conducted a serological survey of pregnant women attending prenatal clinics in northeastern Romania to determine the prevalence of hepatitis B virus (HBV) infection in this population. Overall, 162 (28%) of 573 women had evidence of past or current HBV infection, and 48 (8.4%) were carriers. The prevalence of past or current infection rose with age, but did not differ by educational level, occupation, or rural versus urban residence. Integration of hepatitis B vaccine into routine childhood immunization schedules, with the first dose given at birth, may have a substantial impact on HBV infection in Romania by preventing both perinatal and early childhood transmission.
