There Are Several Pathogens That Cause Viral Hepatitis
Viral hepatitis is primarily caused by four different types of viruses: Hepatitis A virus (HAV), Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Hepatitis E virus (HEV). Among these, HBV is a DNA virus, while the other three belong to the RNA virus family.
Transmission routes vary depending on the type of hepatitis. Hepatitis A and Hepatitis E are mainly transmitted through the fecal-oral route. This occurs when contaminated water or food, which has not been properly boiled or disinfected, infects individuals who come into contact with it. The presence of the virus in the feces of infected persons contributes to its spread in areas with poor sanitation.
In contrast, Hepatitis B and Hepatitis C are primarily spread through bloodborne transmission, sexual contact, and from mother to child during birth. Hepatitis C is especially associated with blood exposure, with over 80% of infections occurring through this route. These transmission patterns highlight the importance of blood safety and preventive measures in reducing the spread of these diseases.
Understanding the different pathogens and their modes of transmission is essential for effective prevention and control strategies. Public health initiatives focusing on sanitation, vaccination, and safe medical practices play a critical role in minimizing the global burden of viral hepatitis.
