What is Zoonotic Hepatitis E?
Zoonotic hepatitis E is a form of hepatitis E virus (HEV) infection transmitted from animals to humans. It primarily involves genotypes found in pigs, wild boars, and deer, and can cause liver inflammation in humans.
What Causes Zoonotic Hepatitis E?
- Consumption of Contaminated Meat – Eating undercooked or raw pork, wild boar, or deer meat infected with HEV.
- Contact with Infected Animals – Handling animals carrying the virus, especially pigs.
- Contaminated Water – In some cases, water contaminated by animal feces containing HEV can spread the infection.
What Are the Symptoms of Zoonotic Hepatitis E?
Symptoms typically appear 2 to 8 weeks after exposure and may include:
- Jaundice (yellowing of the skin and eyes)
- Fatigue and weakness
- Fever
- Nausea and vomiting
- Abdominal pain, especially near the liver
- Dark urine and pale stools
- Loss of appetite
How is Zoonotic Hepatitis E Diagnosed?
- Blood Tests – Detection of HEV antibodies (IgM and IgG) or HEV RNA to confirm infection.
- Liver Function Tests – To assess liver inflammation or damage.
- Medical History – Evaluating exposure to animals, meat consumption, or contaminated water.
How is Zoonotic Hepatitis E Treated?
- Supportive Care – Most cases resolve on their own with rest and hydration.
- Hospitalization – For severe cases, especially in people with liver disease or weakened immune systems.
- Antiviral Medications – Rarely used, but may be considered in chronic cases or immunocompromised patients.
Prognosis of Zoonotic Hepatitis E
Most individuals recover completely without lasting liver damage. However, infection can be severe or fatal in pregnant women or those with pre-existing liver conditions.
Can Zoonotic Hepatitis E Be Prevented?
- Avoid Eating Undercooked Meat – Especially pork, wild boar, and deer.
- Practice Good Hygiene – Handwashing after handling animals or raw meat.
- Ensure Safe Drinking Water – Avoid water potentially contaminated by animal waste.
- Control Measures in Animals – Managing HEV infections in livestock populations.
