Hepatitis A and E (हेपेटाइटिस in Hindi, ஹெபடைடிஸ் in Tamil, ಹೆಪಟೈಟಿಸ್ in Kannada) are two of the most common waterborne liver infections in India, and both spike predictably during and after monsoon season when contaminated water supplies mix with sewage, particularly in areas with older infrastructure or informal settlements. While both cause similar liver inflammation, understanding their differences matters — especially for pregnant women, for whom Hepatitis E carries meaningfully higher risk.
This guide explains how these infections spread through contaminated water, what symptoms to watch for, and how to protect your family.
1. How Hepatitis A and E Spread
Both viruses spread primarily through the faecal-oral route — meaning contaminated water or food that has come into contact with infected faecal matter, often due to inadequate sewage treatment mixing with drinking water supplies. This is especially common during monsoon when heavy rains can overwhelm water treatment systems and cause sewage overflow into water sources, a recurring problem in many Indian cities and towns with ageing infrastructure. Contaminated ice, raw or undercooked shellfish, and unwashed fruits and vegetables washed with contaminated water are also common transmission routes.
2. Key Differences Between Hepatitis A and Hepatitis E
| Feature | Hepatitis A | Hepatitis E |
|---|---|---|
| Most affected group | Children and young adults | Adults, including pregnant women |
| Severity | Usually mild, self-limiting | Usually mild, but can be severe in pregnancy |
| Pregnancy risk | Generally not significantly elevated | Significantly elevated risk of severe liver failure, especially in third trimester |
| Chronic infection | Does not become chronic | Rarely can become chronic in people with weakened immunity |
| Vaccine availability | Widely available in India | Available but less widely used |
This distinction matters practically: while both conditions are usually manageable, Hepatitis E in pregnancy is treated with particular caution and urgency given the meaningfully higher risk of serious complications, which isn't the case with Hepatitis A. Acute Hepatitis E is worth specific attention during India's monsoon months given how common contaminated water exposure becomes during this period.
3. Recognising the Symptoms
Both infections cause similar symptoms: yellowing of the skin and eyes (jaundice, known as "peeliya" in Hindi), dark-coloured urine, pale or clay-coloured stools, fatigue, loss of appetite, nausea, vomiting, mild fever, and sometimes abdominal discomfort in the upper right area where the liver sits. Some people, especially young children with Hepatitis A, may have very mild symptoms or none at all, while still being capable of spreading the infection to others.
Jaundice is often the symptom that finally prompts a doctor's visit, since the yellowing of the eyes and skin is visually obvious to family members even when the person affected has been dismissing earlier fatigue or appetite loss as unrelated.
4. Diagnosis and Treatment
Diagnosis involves blood tests checking liver function (elevated liver enzymes are typical) along with specific antibody tests (IgM anti-HAV for Hepatitis A, IgM anti-HEV for Hepatitis E) to confirm which virus is responsible. There is no specific antiviral treatment for either Hepatitis A or E in most cases — treatment focuses on supportive care: adequate rest, staying hydrated, avoiding alcohol and medications that stress the liver (always check with your doctor before taking any medication, including common painkillers), and eating light, easily digestible meals as appetite allows.
Most people recover fully within a few weeks to two months, though fatigue and reduced appetite can linger even after jaundice improves. Severe cases, particularly Hepatitis E in pregnant women or Hepatitis A/E in people with pre-existing liver conditions, may need hospitalisation for closer monitoring and supportive treatment.
5. Prevention — Protecting Your Family During Monsoon
Since both infections spread through contaminated water and food, prevention overlaps significantly with other monsoon illnesses: drink only boiled or properly filtered water, avoid ice from unreliable sources, wash fruits and vegetables thoroughly with clean water, avoid raw or undercooked shellfish, and maintain good hand hygiene, especially before eating and after using the toilet. The Hepatitis A vaccine is widely available in India and often recommended for children, even though it may not be part of the free government immunisation schedule — worth discussing with your paediatrician as part of a broader vaccination plan.
Pregnant women in particular should be extra cautious about water and food safety during monsoon months, given the elevated risk Hepatitis E poses during pregnancy. For a broader look at monsoon-related illnesses beyond mosquito-borne diseases, see our guides on monsoon diseases in India and leptospirosis after flood exposure, both of which share similar water-safety prevention principles.
Frequently Asked Questions
What is the difference between Hepatitis A and Hepatitis E?
Both Hepatitis A and E spread through contaminated food and water and cause similar liver inflammation symptoms, but Hepatitis A mostly affects children and usually resolves without complications, while Hepatitis E can be significantly more dangerous in pregnant women, sometimes causing severe liver failure. Both are more common in India during and after the monsoon season.
What are the symptoms of Hepatitis A or E?
Common symptoms include yellowing of the skin and eyes (jaundice), dark urine, pale stools, fatigue, loss of appetite, nausea, vomiting, and mild fever. Some people, especially young children, may have very mild or no symptoms at all despite being infected.
Why is Hepatitis E particularly dangerous during pregnancy?
Hepatitis E infection during pregnancy, especially in the third trimester, carries a significantly higher risk of severe liver failure and can be life-threatening for both mother and baby, unlike Hepatitis A which generally does not carry this same elevated pregnancy risk. Pregnant women should be especially careful about water and food safety during monsoon season.
Is there a vaccine for Hepatitis A or E in India?
Yes, a Hepatitis A vaccine is available in India and is often recommended for children as part of extended immunisation schedules, though it may not be part of the free government schedule. A Hepatitis E vaccine has been developed and is licensed in some countries including India, though its use is not yet as widespread as the Hepatitis A vaccine.
How long does recovery from Hepatitis A or E take?
Most people recover from Hepatitis A within a few weeks to two months with rest and supportive care, while Hepatitis E recovery timelines are similar for uncomplicated cases. Fatigue and reduced appetite can linger for several weeks even after jaundice and other symptoms improve, so a gradual return to normal activity is generally recommended.
