Current knowledge of hepatitis E virus related disease

Area of Science:

• Hepatology
• Virology
• Zoonotic Diseases

Background:

• Hepatitis E virus (HEV) is a leading cause of acute hepatitis globally.
• HEV genotype 3 is endemic in the Czech Republic, posing a zoonotic risk.
• HEV infections present diverse clinical features, including extrahepatic manifestations and chronic hepatitis in immunocompromised individuals.

Purpose of the Study:

• To review current knowledge on Hepatitis E virus related diseases.
• To summarize contemporary approaches to treating acute and chronic Hepatitis E.
• To highlight the zoonotic nature and epidemiological characteristics of HEV in industrialized countries.

Main Methods:

• Literature review of HEV epidemiology, clinical presentation, and treatment.
• Synthesis of data on HEV genotype 3 in the Czech Republic.
• Analysis of transmission routes, focusing on zoonotic aspects.

Main Results:

• HEV is a significant global health issue with endemic genotype 3 in the Czech Republic.
• Zoonotic transmission, primarily through undercooked meat, is a key route in industrialized nations.
• HEV can cause extrahepatic symptoms and chronic disease in specific patient groups.

Conclusions:

• Understanding HEV's diverse manifestations and transmission is crucial for public health.
• Effective management strategies for acute and chronic HEV are essential.
• Continued research into HEV, particularly genotype 3, is needed to combat its spread and impact.
