The Silent Spread of Hepatitis E in India

Hepatitis E virus (HEV) is often overlooked, but recent outbreaks in India—especially in flood-affected regions—highlight its growing threat. Unlike Hepatitis B or C, HEV spreads primarily through contaminated water, making monsoons and poor sanitation high-risk periods. Pregnant women, particularly in the third trimester, face severe complications like acute liver failure and mortality rates up to 20%.

How Hepatitis E Spreads

Fecal-oral route: Contaminated water (e.g., during floods) is the main source.
Undercooked meat: Pork and shellfish can carry HEV.
Person-to-person: Rare, but possible in crowded, unhygienic conditions.

Warning

HEV is often misdiagnosed as other hepatitis types due to similar symptoms (jaundice, fatigue). Confirm with IgM anti-HEV testing.

Why Pregnant Women Are Vulnerable

Hormonal and immune changes during pregnancy worsen HEV outcomes:
1. Fulminant hepatitis: Rapid liver damage, leading to encephalopathy.
2. High fetal mortality: Miscarriage or preterm delivery risks increase.
3. Limited treatment options: No specific antiviral therapy exists; management is supportive.

Emergency

Seek immediate care if a pregnant woman develops jaundice, vomiting, or confusion. Delayed treatment can be fatal.

Prevention Strategies

Boil or purify water during monsoons/floods.
Avoid street food in outbreak zones.
Vaccine awareness: China’s HEV vaccine isn’t yet available in India, but advocacy is growing.
