Summary

Hepatitis C virus (HCV) infection is highly prevalent in endemic areas, affecting 24.1% of residents, particularly those over 50. Risk factors include blood transfusions and acupuncture, contributing to rising liver disease mortality.

Area of Science:

Hepatology
Virology
Public Health

Context:

N Town's A.H. areas have been recognized as endemic for hepatitis since 1985.
Mass health screening was conducted to assess liver disease prevalence and risk factors.

Purpose:

To determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in endemic and non-endemic areas.
To identify risk factors associated with HCV infection.
To provide health education on hepatitis prevention and liver disease management.

Summary:

The study involved 1,000 inhabitants from endemic A.H. areas and 1,795 from non-endemic control areas, aged six and older.
Prevalence of anti-HCV was significantly higher in endemic areas (24.1%) compared to control areas (2.3%), increasing with age over 50.
Hepatitis B surface antigen (HBsAg) prevalence was similar in both areas.
Identified risk factors for HCV infection included blood transfusion, acupuncture, a history of liver disease, and positive anti-HBs.
Death rates from liver cirrhosis and hepatocellular carcinoma are increasing.

Impact:

Highlights the significant burden of HCV in endemic regions and identifies key transmission routes.
Provides crucial data for targeted public health interventions and prevention strategies.
Emphasizes the need for continued monitoring and health education to combat rising liver disease mortality.
