Hepatitis EHepatitis E virus (HEV) infection
Medically reviewed
Hepatitis E is a liver infection caused by the hepatitis E virus (HEV). It spreads mostly through contaminated drinking water and poor sanitation, and it can also spread through undercooked meat from infected animals. In most people the infection clears on its own within 4 to 6 weeks, and many people have no symptoms. Rarely, it causes severe liver failure. There is no specific treatment, so care focuses on rest, fluids, and avoiding alcohol.
Hepatitis E is uncommon in the United States. It is most often linked to travel to parts of Asia, the Middle East, Africa, or Central America. When symptoms appear, they start 3 to 8 weeks after infection and can include jaundice, fever, nausea, and abdominal pain. Blood tests confirm the diagnosis. People with weakened immune systems and pregnant women face higher risks and should talk to a doctor promptly. A hepatitis E vaccine exists, but it is approved only in China, so prevention relies on clean water, good hand hygiene, and well-cooked food.

About hepatitis E
What Is Hepatitis E?
Hepatitis E is a liver infection caused by the hepatitis E virus (HEV), an RNA virus. Doctors first told it apart from hepatitis A in 1980. Before that, it was called non-A, non-B hepatitis.
Hepatitis E is uncommon in the United States. An estimated one in 1 million U.S. residents is infected each year, usually after travel to Asia, the Middle East, Africa, or Central America. Worldwide, about 20 million people are infected each year, and the infection is most common in East Asia and South Asia.
Hepatitis E is a self-limiting infection, which means it usually clears on its own in 4 to 6 weeks. Occasionally, a severe form called fulminant hepatitis develops. Fulminant hepatitis can lead to liver failure or death.
The virus comes in different genotypes. Genotypes 1 and 2 infect only people and spread through contaminated water where sanitation is poor, mostly in parts of Asia, Africa, and Mexico. They usually cause a brief illness in young adults. Genotypes 3 and 4 also infect animals, including pigs, wild boar, and deer. They tend to affect older men in developed countries, and they can become chronic in people with weakened immune systems.
Symptoms appear 3 to 8 weeks after infection, and the average is about 40 days. Many people, especially children, have no symptoms or only mild ones.
How hepatitis E may feel
Symptoms of Hepatitis E
Hepatitis E can cause no symptoms at all. When symptoms do appear, they look like other types of acute viral hepatitis. They are most common in young adults aged 15 to 40.
Common Symptoms
- Abdominal pain
- Enlarged liver
- Fever
- Jaundice (yellowing of the skin and whites of the eyes)
- Loss of appetite
- Nausea
- Vomiting
- A vague sense of feeling unwell
Who May Have Milder or No Symptoms
- Children, who often have no symptoms or mild illness without jaundice
- Adults who clear the virus without noticing an illness
- People in the first 3 to 8 weeks after infection, before symptoms appear
Rare and Severe Problems
- Fulminant hepatitis, which can cause liver failure
- Long-lasting infection in people with weakened immune systems
- Nerve problems outside the liver, such as Guillain-Barré syndrome, neuralgic amyotrophy, and encephalitis or myelitis
Getting checked
How Hepatitis E Is Diagnosed
Hepatitis E is diagnosed with blood tests. Symptoms alone cannot confirm it, because the illness looks like other types of acute viral hepatitis.
- Hepatitis E Antibody Test
- A blood test that looks for antibodies your body makes in response to the hepatitis E virus.
- HEV RNA Test
- A blood test that looks for the genetic material of the virus. It shows whether the virus is active in your body, and doctors use it to check for long-lasting infection.
Key Fact About Hepatitis E Testing:
Hepatitis E cannot be told apart from other acute viral hepatitis by symptoms, so a blood test for HEV antibodies or HEV RNA is needed to confirm it.
Care & prevention
Treatment & Prevention Overview
There is no specific treatment for hepatitis E, so prevention is the focus. Most people recover with supportive care at home.
Chronic Infection in People With Weakened Immune Systems
In people with weakened immune systems, hepatitis E can become a long-lasting infection. For transplant recipients, the first step is usually to lower the dose of immune-suppressing medicine, if their doctor decides it is safe. This lets the immune system regain control, and nearly one-third of chronically infected transplant recipients clear the virus this way. If the virus is still present three months after it is found, doctors may prescribe a 12-week course of the antiviral medicine ribavirin, which may be extended if the virus is still detectable afterward.
Severe Illness and Pregnancy
Ribavirin may also be considered in severe acute hepatitis E or when a person develops acute-on-chronic liver failure. Hepatitis E during pregnancy can cause pregnancy complications or liver failure, so pregnant women with suspected hepatitis E need prompt medical care.
Prevention and Vaccine
A hepatitis E vaccine exists, but it has been approved for use only in China. When you travel to an area where hepatitis E is common, drink clean, filtered water and skip ice of unknown purity. Wash your hands with clean water, especially before handling food. Avoid uncooked shellfish and uncooked fruits and vegetables.
Key Fact About Hepatitis E Treatment:
There is no specific treatment for hepatitis E. Most people recover on their own in 4 to 6 weeks with rest, fluids, and no alcohol.
How hepatitis E spreads
Causes & Risk Factors
Hepatitis E spreads mainly through the fecal-oral route, which means the virus passes from stool into the mouth, usually through contaminated water or inadequate sanitation. Some types also spread through food from infected animals.
How It Spreads
- Drinking contaminated water
- Poor sanitation in the environment
- Eating food from infected animals, such as undercooked pork, wild boar, or deer
- Eating raw or undercooked shellfish
- Receiving a blood transfusion with infected blood products
- Passing from a mother to her child
Who Is at Higher Risk
- Travelers to areas where hepatitis E is common, such as parts of Asia, the Middle East, Africa, and Central America
- People living where sanitation and clean water are limited
- People who eat undercooked meat from pigs, wild boar, or deer
- Solid organ transplant recipients
- People with blood cancers, people living with HIV, and people on heavy immune-suppressing medicine
- People with chronic liver disease, who are advised to avoid undercooked meat and shellfish
- Pregnant women
Key Facts Overview:
Hepatitis E spreads mostly through contaminated water and undercooked food. Clean water, good hand hygiene, and well-cooked meat lower the risk.
When to get checked
When Should You See a Doctor for Hepatitis E?
Hepatitis E often causes no symptoms and clears on its own, so many people never know they had it. Still, some situations call for medical care and testing.
Who Should Get Tested
Talk to a healthcare provider if you have symptoms such as jaundice, fever, nausea, vomiting, loss of appetite, or abdominal pain, especially after travel to Asia, the Middle East, Africa, or Central America, or after eating undercooked pork, wild boar, or deer meat.
Warning Signs That Need Prompt Evaluation
Seek care right away if you are pregnant and think you may have hepatitis E, since the infection can cause pregnancy complications or liver failure. Get urgent help for severe symptoms that could signal fulminant hepatitis, such as worsening jaundice, confusion, or a fast decline in how you feel.
Extra Care for People at Higher Risk
If you have had a transplant, live with HIV, take heavy immune-suppressing medicine, or have chronic liver disease, ask your doctor about hepatitis E. People with weakened immune systems can develop a long-lasting infection, and a blood test for HEV RNA can show whether the virus is still present.
Getting the Right Specialist Care
A gastroenterologist or hepatologist can confirm the diagnosis, check how your liver is doing, and guide treatment if the infection is severe or long-lasting.

Eating & liver health
Liver-Healthy Diet for Hepatitis E
Diet does not treat hepatitis E, but eating well supports your liver while it heals. Care centers on rest, enough nutrients and fluids, and no alcohol. A balanced, liver-healthy diet is low in fat, salt, and refined sugar.
Alcohol can add to liver damage, so avoid it while you recover. Limit fast food, sweets, and soft drinks. Food safety matters too: avoid uncooked shellfish such as oysters and clams, and cook pork, wild boar, and deer meat to at least 158°F (70°C). People with weakened immune systems or chronic liver disease should be especially careful. Cook with olive or flaxseed oil instead of butter, and choose lean meats such as turkey or salmon.
Smaller meals every three to four hours can be easier to manage than a few large ones. Needs differ with the stage of liver disease, so check with your doctor or a dietitian before you change your diet or take supplements.
Foods That Support Your Liver With Hepatitis E
- Lean protein, such as chicken, turkey, or salmon, cooked well
- Olive oil and flaxseed oil in place of butter
- Whole grains and high-fiber foods, such as brown rice and bananas
- Fruits and vegetables, such as broccoli, garlic, and leafy greens
- Omega-3 snacks, such as edamame and blackberries
Common questions
Answers to Common Hepatitis E Questions
Does hepatitis E go away on its own?
Yes, in most cases. Hepatitis E is a self-limiting infection, which means it usually clears on its own in 4 to 6 weeks without specific treatment. Care focuses on rest, enough nutrients and fluids, and avoiding alcohol, and most people do not need to go to the hospital. People with weakened immune systems can develop a long-lasting infection. For transplant recipients, doctors may first lower the dose of immune-suppressing medicine if it is safe, and they may prescribe the antiviral medicine ribavirin if the virus remains.
Is there a vaccine for hepatitis E?
Not in the United States. A hepatitis E vaccine exists, but it has been approved for use only in China. Because of this, prevention relies on clean drinking water, good hand hygiene, and well-cooked food. If you travel to an area where hepatitis E is common, ask your doctor how to protect yourself before you go.
How do you get hepatitis E?
Hepatitis E spreads mostly through drinking water contaminated with the virus and through poor sanitation. This is called the fecal-oral route, because the virus passes from stool into the mouth. It can also spread by eating undercooked pork, wild boar, or deer meat, by eating raw or undercooked shellfish, through infected blood transfusions, and from mother to child.
Can you have hepatitis E without symptoms?
Yes. Many people with hepatitis E, especially children, have no symptoms or only mild ones, so they may never know they were infected. When symptoms appear, they usually start 3 to 8 weeks after infection, about 40 days on average. They can include jaundice, fever, nausea, vomiting, loss of appetite, and abdominal pain.
How is hepatitis E diagnosed?
Blood tests diagnose hepatitis E. Doctors check for antibodies your body makes against the virus, or for HEV RNA, the virus's genetic material. The RNA test shows whether the virus is active, and doctors also use it to check for long-lasting infection. Symptoms alone cannot confirm hepatitis E, because the illness looks like other types of acute viral hepatitis.
Who is at higher risk of serious hepatitis E?
People with weakened immune systems and pregnant women face the highest risks. Solid organ transplant recipients, people with blood cancers, people living with HIV, and people who take heavy immune-suppressing medicine can develop a long-lasting infection. During pregnancy, hepatitis E can cause pregnancy complications or liver failure, so pregnant women with suspected hepatitis E need prompt medical care. People with chronic liver disease are advised to avoid undercooked meat and shellfish.
