What it is
Hepatitis A is a viral infection that affects the liver. It is caused by the hepatitis A virus, which is passed in the stool of an infected person. Unlike hepatitis B and C, hepatitis A is generally acute and self-limited, meaning it does not typically become a long-term chronic infection.
Hepatitis A transmission is described as the fecal-oral route. In everyday terms, tiny amounts of the virus get from one person's stool into another person's mouth. This can happen through food or drink handled by someone who is infected, through contaminated water, or through close personal contact, including some types of sexual contact.
The virus can spread before a person feels sick or notices symptoms, which is one reason it can pass between people unnoticed. Hand washing, food safety, and clean water all play a role in how it moves through communities. Some people have mild symptoms or none at all, while others feel quite unwell, so only a clinician can say what is going on for any one person.
How it’s traditionally been approached
Public health approaches have long focused on interrupting the fecal-oral route. This commonly includes careful hand washing after using the bathroom and before preparing or eating food, safe drinking water, and proper sanitation.
Vaccination has also been a widely used way to lower the chance of infection. Hepatitis A vaccines are FDA-approved, and clinicians commonly discuss them for children and for adults who may be at higher risk, such as people traveling to regions where the virus is more common, people experiencing homelessness, people who use drugs, and others a provider identifies.
When someone has been exposed, clinicians have traditionally considered options that may help, depending on the person's situation and timing. Care for an infection is generally supportive and guided by a licensed provider, who decides what is appropriate after an evaluation.
How the right doctor may help
The right doctor may help you understand your own situation, including whether you may have been exposed, whether you have symptoms worth checking, and whether vaccination is something to consider. A visit generally starts with a conversation about your health history, travel, food and household exposures, and any symptoms.
Depending on your circumstances, a clinician may talk with you about blood tests, vaccination status, or monitoring. Whether any of these are right for you is a decision for a licensed professional after an evaluation. Nothing on this page replaces that conversation.
Helpful questions to bring: How might I have been exposed? Should I be vaccinated, and is it appropriate for my situation? How can I protect the people I live with? When should I seek urgent care? If you are looking for a licensed professional, Providers.plus lists providers, including those focused on hepatitis A care.
The whole-person view
Body, mind, and stress affect each other. Feeling unwell, worrying about exposure, or being away from work or family can all weigh on your mood and energy, and stress can in turn make recovery from any illness feel harder.
Many people find that whole-person support complements medical care. Somatic Experiences offers body-based support for stress and tension, and Therapists.plus offers talk therapy for worry or the emotional side of being ill. These are optional additions that work alongside, not in place of, guidance from your doctor.
Keep in mind
- Hepatitis A transmission and prevention should be discussed with a licensed clinician, who can guide care based on your personal situation.

- Severe symptoms such as confusion, severe abdominal pain, vomiting blood, or significant yellowing of the skin or eyes with fever need emergency care. Call 911.

Frequently asked questions
How is hepatitis A transmitted?
Hepatitis A is transmitted mainly through the fecal-oral route, meaning the virus is swallowed after contact with the stool of an infected person. This can happen through contaminated food or water, or through close personal contact. A licensed clinician can explain how this applies to your situation.
Can you get hepatitis A from food?
Yes, food can carry the virus if it is handled by an infected person who has not washed their hands well, or if it is contaminated by unsafe water. Good hand washing and food safety practices are traditionally used to lower this risk. Ask a provider about your own risk, especially before travel.
Can hepatitis A spread through sexual contact or close contact?
It can. Close household contact and some types of sexual contact may allow the virus to pass from one person to another. This is a factual public health point and carries no stigma. A clinician can talk with you privately about prevention.
Can you spread hepatitis A without symptoms?
Yes, a person can have the virus and pass it on before symptoms appear, and some people never notice symptoms at all. That is one reason hygiene and vaccination are discussed so often. Only a clinician can tell you whether you have an infection.
Is there a vaccine that helps with hepatitis A transmission?
Yes, hepatitis A vaccines are FDA-approved and are commonly discussed with a licensed clinician as a way to lower the chance of infection. Whether vaccination is appropriate for you depends on your age, health, and exposures. Ask your provider whether it makes sense for you.
Does hepatitis A become a chronic infection like hepatitis B or C?
Hepatitis A is generally acute and self-limited, so it does not usually become a chronic infection the way hepatitis B and C can. Even so, how a person feels and recovers can vary. A doctor can guide care and monitoring based on your health.
