Hepatitis is an inflammation of the liver caused by various factors, including infections by hepatitis viruses. There are five main types of hepatitis viruses, labeled as Hepatitis A, B, C, D, and E. Each type is unique in its mode of transmission, severity, and impact on health.
- Hepatitis A (HAV): This type is typically transmitted through the consumption of contaminated food or water. It is acute but rarely leads to long-term liver damage.
- Hepatitis B (HBV): Spread through contact with infected blood, semen, or other body fluids, Hepatitis B can cause both acute and chronic infections, leading to severe liver complications.
- Hepatitis C (HCV): This virus is mainly spread through blood-to-blood contact, such as sharing needles. Chronic Hepatitis C can result in liver cirrhosis or cancer if untreated.
- Hepatitis D (HDV): Often referred to as a “satellite virus,” Hepatitis D only occurs in people already infected with Hepatitis B. It can lead to more severe liver disease.
- Hepatitis E (HEV): Typically transmitted through contaminated drinking water, Hepatitis E usually resolves on its own but can be more severe in pregnant women.
Awareness, vaccinations, and preventive measures are crucial in managing and reducing the impact of these viruses globally.
