Hepatitis B infection is one of the world's most serious public health problems, causing significant morbidity and mortality. More than 2 billion individuals around the world have been infected with the hepatitis B virus (HBV), and approximately 400 million people are chronically infected with the virus, with more than a million dying each year from hepatitis B virus-related liver disease. A newborn infant whose mother is positive for both HBsAg and HBeAg has a 90% chance of developing chronic infection by the age of 6. Its infectivity is a 100 times that of the human immunodeficiency virus, but it receives little attention in public health. Therefore, this study was conducted to assess the prevalence of
This institution-based cross-sectional study was conducted on 300 pregnant mothers selected by systematic random sampling from September to December 2020. Data were collected by face-to-face interview using a pretested structured questionnaire. A blood sample was collected and tested for
The overall seroprevalence of
The hepatitis B virus was highly prevalent. A history of tonsillectomy, tattooing, having multiple partners, and contact with jaundiced patients were factors associated with hepatitis B virus infection. To reduce HBV transmissions, the government should increase HBV vaccination coverage. All newborns should receive the hepatitis B vaccine as soon as possible after birth. It is also recommended that all pregnant women have HBsAg testing and antiviral prophylaxis to reduce the risk of transmission from mother to child. Hospitals, districts, regional health bureaus, and medical professionals should also educate pregnant women about hepatitis B virus transmission and prevention, both in the hospital and in the community, with a focus on modifiable risk factors.
