Hepatitis E virus: epidemiology, diagnosis, pathology and prevention

Area of Science:

• Hepatology
• Virology
• Public Health

Background:

• Hepatitis E virus (HEV) is a major cause of epidemic hepatitis in developing countries.
• It is transmitted primarily through contaminated water and is a leading cause of acute hepatitis and liver failure in endemic areas.
• HEV poses significant risks to pregnant women and individuals with pre-existing liver conditions.

Purpose of the Study:

• To review the epidemiology, transmission, and clinical impact of Hepatitis E virus.
• To discuss diagnostic methods and potential future interventions for HEV.
• To highlight public health strategies for preventing HEV outbreaks.

Main Methods:

• Literature review of HEV epidemiology and clinical studies.
• Analysis of transmission routes, including waterborne, parenteral, and vertical transmission.
• Evaluation of current diagnostic tools and vaccine development prospects.

Main Results:

• HEV is responsible for most hepatitis epidemics in the developing world.
• Serodiagnosis for HEV is available and recommended for routine diagnosis.
• Evidence suggests parenteral and vertical HEV transmission occurs, especially in endemic regions.

Conclusions:

• Hepatitis E virus presents a significant public health challenge, particularly in resource-limited settings.
• While an HEV vaccine is anticipated, current prevention relies on improved sanitation, clean water, and public education.
• Routine serodiagnosis is crucial for managing HEV infections.
