Insights
Hepatitis B virus infection markers were found in 0.8% of Lebanese children. The risk of transmission increases after age two, necessitating hepatitis B vaccination in infancy.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Hepatitis B virus (HBV) infection poses a significant global health burden, particularly in developing regions.
- Understanding the prevalence of HBV infection markers in pediatric populations is crucial for effective public health strategies.
- Lebanon's immunization policies require updated data on childhood HBV infection status.
Purpose of the Study:
- To determine the prevalence of hepatitis B infection markers in Lebanese children aged 6 months to 6.5 years.
- To identify age-specific infection rates and potential risk factors.
- To inform recommendations for childhood immunization policies in Lebanon.
Main Methods:
- A multi-center, cross-sectional study involving 841 children from Lebanon's five districts.
- Sera were tested for hepatitis B surface antigen and hepatitis B core IgG.
- Data analysis included age-specific prevalence rates and associations with family characteristics.
Main Results:
- The overall prevalence of hepatitis B virus infection markers was 0.8%.
- Prevalence increased with age, from 0% at 6 months to 1.3% in children over 5 years.
- Higher prevalence rates were observed in Beirut suburbs (2.9%) and South Lebanon (1.6%).
- No significant association was found between infection markers and family characteristics or risk factors.
- The risk of horizontal transmission increased substantially after age 2 years.
Conclusions:
- Hepatitis B virus infection is present in Lebanese children, with increasing prevalence in older age groups.
- The findings highlight the need for integrating the hepatitis B vaccine into routine childhood immunization programs.
- Early vaccination is recommended to mitigate the risk of horizontal transmission and protect children from HBV infection.
Abstract:
This multi-centre, cross-sectional study was designed to reveal the present status of hepatitis B infection markers among Lebanese children, and provide recommendations regarding childhood immunization policies. A total of 841 children, aged between 6 months and 6.5 years, were enrolled from Lebanon's five districts. Their sera were tested for hepatitis B surface antigen and hepatitis B core IgG. The overall prevalence of hepatitis B virus infection markers was 0.8% with increasing age-specific rates from 0% at 6 months to 1.3 % at > 5 years. There was no statistically significant association between the presence of hepatitis B markers and family characteristics or risk factors for infection. The highest prevalence rates were among children from Beirut suburbs (2.9 %) and South Lebanon (1.6%). The risk of horizontal transmission of hepatitis B to uninfected children increased substantially after the age of 2 years. An expanded programme on immunization that integrates hepatitisB vaccine during the first year of life is needed.
