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.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
