Acta Obstet. For example, mother-to-child transmission of hepatitis B can be prevented by vaccination within 24 hours of birth. In Myanmar, the expanded programme for immunization is working closely with the national hepatitis control programme to provide immunization for hepatitis B, such as birth-dose and childhood vaccinations nationwide. However, even infants who have received appropriate PEP can become infected, typically when the mother has a high HBV viral load during pregnancy. • Hepatitis B IgM antibody to core antigen (IgM anti HBc): A positive result indicates recent/acute infection with HBV (≤ six months). (See Recommendations for Initial HCV Testing and Follow-Up .) Study: A hospital-based case-control study was conducted. If the HBV DNA (viral load) blood test is not available or is cost prohibitive, then pregnant people should be tested for HBeAg (a blood test). For women who may have difficulty returning for multiple blood tests, a viral load may be arranged on the initial follow-up of the positive Hepatitis B antigen . The introduction of a collaborative referral pathway for pregnant women with hepatitis B significantly improved the assessment of viral load during pregnancy and provided an opportunity to link women into ongoing care.
