Summary
Hepatitis B infection is a common cause of acute viral hepatitis in Nigeria, affecting nearly half of patients studied. Further research is needed to understand transmission routes for this frequent hepatitis B infection.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Viral hepatitis poses a significant public health challenge globally.
- Hepatitis B virus (HBV) is a primary cause of acute and chronic liver disease.
- Understanding the epidemiology of viral hepatitis in specific regions is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of Hepatitis B surface antigen (HBsAg) in patients with acute viral hepatitis.
- To investigate the potential causes and modes of transmission for acute viral hepatitis in Nigeria.
Main Methods:
- Retrospective analysis of 97 patients diagnosed with acute viral hepatitis.
- Detection of Hepatitis B surface antigen (HBsAg) using serological assays.
- Clinical data review to assess potential infection sources.
Main Results:
- Hepatitis B surface antigen (HBsAg) was detected in 46.4% of the 97 patients.
- The specific mode of infection could not be determined in most cases.
- Hepatitis B infection was identified as a frequent cause of acute viral hepatitis in the studied population.
Conclusions:
- Hepatitis B virus (HBV) is a significant contributor to acute viral hepatitis cases in Nigeria.
- The high prevalence of HBsAg underscores the need for improved hepatitis B prevention and control strategies.
- Further epidemiological studies are warranted to elucidate transmission patterns of hepatitis B in Nigeria.
