What is Hepatitis A – FAQ

Overview

What is hepatitis?

Hepatitis means inflammation of the liver. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis, but it is often caused by a virus. In the United States, the most common hepatitis viruses are hepatitis A virus, hepatitis B virus, and hepatitis C virus.

What is the difference between hepatitis A, hepatitis B, and hepatitis C?

Hepatitis A, hepatitis B, and hepatitis C are liver infections caused by three different viruses. Although each can cause similar symptoms, they are spread in different ways and can affect the liver differently. Hepatitis A is usually a short-term infection and does not become chronic. Hepatitis B and hepatitis C can also begin as short-term, acute infections, but in some people, the virus remains in the body, resulting in chronic disease and long-term liver problems. There are vaccines to prevent hepatitis A and hepatitis B; however, there is no vaccine for hepatitis C.

What is hepatitis A?

Hepatitis A is a highly contagious, short-term liver infection caused by the hepatitis A virus.

How serious is hepatitis A?

People who get hepatitis A may feel sick for a few weeks to several months but usually recover completely and do not have lasting liver damage. In rare cases, hepatitis A can cause liver failure and even death; this is more common in older people and in people with other serious health issues, such as chronic liver disease.

How common is hepatitis A in the United States?

In 2018, a total of 12,474 hepatitis A cases were reported in the United States. Because some people don’t ever get diagnosed, the actual number of cases reported in that year is probably closer to 24,900. Since 2016, person-to-person outbreaks of hepatitis A have been occurring across the United States mainly among people who use injection drugs or are experiencing homelessness, resulting in more than 32,000 cases.

Are cases of hepatitis A increasing in the United States?

Since the hepatitis A vaccine was first recommended in 1996, cases of hepatitis A in the United States declined dramatically. Unfortunately, in recent years the number of people infected has been increasing because there have been multiple outbreaks of hepatitis A in the United States resulting from person-to-person contact, especially among people who use drugs, people experiencing homelessness, and men who have sex with men.

Transmission / Exposure

How is hepatitis A spread?

The hepatitis A virus is found in the stool and blood of people who are infected. The hepatitis A virus is spread when someone ingests the virus (even in amounts too small to see) through:

►Person-to-person contact

Hepatitis A can be spread from close, personal contact with an infected person, such as through certain types of sexual contact (like oral-anal sex), caring for someone who is ill, or using drugs with others. Hepatitis A is very contagious, and people can even spread the virus before they feel sick.

►Eating contaminated food or drink

Contamination of food with the hepatitis A virus can happen at any point: growing, harvesting, processing, handling, and even after cooking. Contamination of food and water happens more often in countries where hepatitis A is common. Although uncommon, foodborne outbreaks have occurred in the United States from people eating contaminated fresh and frozen imported food products.

Who is at risk for hepatitis A?

Although anyone can get hepatitis A, in the United States, certain groups of people are at higher risk for getting infected and for having severe disease if they do get hepatitis A.

People at increased risk for hepatitis A

• International travelers
• Men who have sex with men
• People who use or inject drugs (all those who use illegal drugs)
• People with occupational risk for exposure
• People who anticipate close personal contact with an international adoptee
• People experiencing homelessness

People at increased risk for severe disease from hepatitis A infection

• People with chronic liver disease, including hepatitis B and hepatitis C
• People with HIV

What should I do if I think I have been exposed to hepatitis A virus?

If you think you have been exposed to the hepatitis A virus, call your health professional or your local or state health department as soon as possible, ideally within 2 weeks. A health professional can decide next steps based on your age and overall health.

Can I prevent infection after an exposure to the hepatitis A virus?

A single shot of the hepatitis A vaccine can help prevent hepatitis A if given within 2 weeks of exposure. Depending upon your age and health, your doctor may recommend immune globulin in addition to the hepatitis A vaccine.

If I have had hepatitis A in the past, can I get it again?

No. Once you recover from hepatitis A, you develop antibodies, protecting you for life.

How long does hepatitis A virus survive outside the body?

The hepatitis A virus can survive outside the body for months. Heating food and liquids to temperatures of 185°F (85°C) for at least 1 minute can kill the virus. Exposure to freezing temperatures does not kill the virus.

Symptoms

What are the symptoms of hepatitis A?

Not everyone with hepatitis A has symptoms. Adults are more likely to have symptoms than children. If symptoms develop, they usually appear 2 to 7 weeks after infection. Symptoms usually last less than 2 months, although some people can be ill for as long as 6 months.

If symptoms develop, they can include:

• Yellow skin or eyes
• Not wanting to eat
• Upset stomach
• Throwing up
• Stomach pain
• Fever
• Dark urine or light- colored stools
• Diarrhea
• Joint pain
• Feeling tired

Can a person spread hepatitis A virus without having symptoms?

Yes. Many people, especially children, have no symptoms but can still spread the infection. In addition, a person can transmit the hepatitis A virus to others up to 2 weeks before symptoms appear.

Diagnosis / Treatment

How is hepatitis A diagnosed?

A doctor can determine if you have hepatitis A by discussing your symptoms and ordering a blood test that can tell whether you have been recently infected with the virus that causes hepatitis A.

How is hepatitis A treated?

To treat the symptoms of hepatitis A, doctors usually recommend rest, adequate nutrition, and fluids. Some people with severe symptoms will need medical care in a hospital.

Prevention / Vaccination

How can I protect myself against hepatitis A?

The best way to prevent hepatitis A is through vaccination with the hepatitis A vaccine. To get the full benefit of the hepatitis A vaccine, more than one shot is needed. The number and timing of these shots depends on the type of vaccine you are given. Practicing good hand hygiene — including thoroughly washing hands after using the bathroom, changing diapers, and before preparing or eating food — plays an important role in preventing the spread of hepatitis A.

Who should get vaccinated against hepatitis A?

The following people should be vaccinated against hepatitis A:

Children

• All children aged 12–23 months
• All children and adolescents 2–18 years of age who have not previously received hepatitis A vaccine (known as “catch up” vaccination)

People at increased risk for hepatitis A

People at increased risk for severe disease from hepatitis A infection

Other people recommended for vaccination

• Pregnant women at risk for hepatitis A or risk for severe outcome from hepatitis A infection
• Any person who requests vaccination

How is the hepatitis A vaccine given?

There are two types of hepatitis A vaccine. The first type, the single-dose hepatitis A vaccine, is given as two shots, 6 months apart, and both shots are needed for long-term protection against hepatitis A. The other type is a combination vaccine that protects people against both hepatitis A and hepatitis B. The combination vaccine can be given to anyone 18 years of age and older and is given as three shots over 6 months. All three shots are needed for long-term protection for both hepatitis A and hepatitis B.

Is the hepatitis A vaccine effective?

Yes, both types of hepatitis A vaccine are highly effective in preventing hepatitis A virus infection. Receiving the entire vaccine series (all of the required shots) results in long-term protection.

Is the hepatitis A vaccine safe?

Yes, the hepatitis A vaccine is safe. No serious side effects have been reported from the hepatitis A vaccine. Soreness at the injection site is the most common side effect reported. As with any medicine, there is always a small risk that a serious problem could occur after someone gets the vaccine. However, the potential risks of hepatitis A are much greater than the potential risks associated with the hepatitis A vaccine. Millions of doses of hepatitis A vaccine have been given in the United States and worldwide since the first hepatitis A vaccine was licensed in 1995.

Who should not receive the hepatitis A vaccine?

People who have ever had a life-threatening allergic reaction to the hepatitis A vaccine or who are known to be allergic to any part of the hepatitis A vaccine should not receive the vaccine. Tell your doctor if you have any severe allergies. Also, the vaccine is not licensed for use in infants under age 1 year.

What is immune globulin?

Immune globulin is a substance made from human blood plasma that contains antibodies, which are the body’s natural defense against infection. Injections of immune globulin may be given under certain circumstances, like when someone is too young to get vaccinated or can’t get vaccinated because of a previous, life-threatening reaction to the hepatitis A vaccine or vaccine component. Unlike the hepatitis A vaccine, immune globulin does not provide long-term protection against infection.

Will the hepatitis A vaccine protect me from other forms of hepatitis?

No. The hepatitis A vaccine only protects against hepatitis A. There is a separate vaccine available for hepatitis B. There is also a combination hepatitis A and hepatitis B vaccine that offers protection for both viruses. There is no vaccine for hepatitis C at this time.

Can hepatitis A vaccine be given to people with compromised immune systems, such as hemodialysis patients or people with HIV/AIDS?

Yes. The hepatitis A vaccine can be given to people with compromised immune systems.

Is it harmful to have an extra dose of hepatitis A vaccine or to repeat the entire hepatitis A vaccine series?

No, getting extra doses of hepatitis A vaccine is not harmful.

What should be done if the last dose of hepatitis A vaccine is delayed?

If the second dose has been delayed (more than 6 months since the first dose was given), it should be given as soon as possible. The first dose does not need to be given again.

Where can I get the hepatitis A vaccine?

Speak with your health-care provider or call your local public health department, where free or low-cost vaccines for adults may be offered. For children, check the Vaccines for Children Program.

Hepatitis A Vaccine and International Travel

Who should get the hepatitis A vaccine before traveling internationally?

All unvaccinated people, along with those who have never had hepatitis A, should be vaccinated before traveling to countries where hepatitis A is common. Travelers to urban areas, resorts, and luxury hotels in countries where hepatitis A is common are still at risk. International travelers have been infected, even though they regularly washed their hands and were careful about what they drank and ate. Those who are too young or can’t get vaccinated because of a previous, life-threatening reaction to the hepatitis A vaccine or vaccine component should receive immune globulin. Travelers to other countries where hepatitis A does not commonly occur are not recommended to receive hepatitis A vaccine before travel.

How soon before travel should I get the hepatitis A vaccine?

You should get the first dose of hepatitis A vaccine as soon as you plan international travel to a country where hepatitis A is common. The vaccine will provide some protection even if you get vaccinated closer to departure. For older adults (age >40 years), people who are immunocompromised, and people with chronic liver disease or other chronic medical conditions the health-care provider may consider, based on several factors, giving an injection of immune globulin at the same time in different limbs.

What should I do if I am traveling internationally but cannot receive hepatitis A vaccine?

People who are allergic to a vaccine component or are younger than 6 months should receive a single dose of immune globulin before traveling to a country where hepatitis A is common. Immune globulin provides effective protection against hepatitis A virus infection for up to 2 months, depending on the dosage given. If you are staying longer than 2 months, you can get another dose of immune globulin during your visit for continued protection against hepatitis A.

Key facts

• Hepatitis A is an inflammation of the liver that can cause mild to severe illness.
• The hepatitis A virus (HAV) is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person.
• Almost everyone recovers fully from hepatitis A with a lifelong immunity. However, a very small proportion of people infected with hepatitis A could die from fulminant hepatitis.
• The risk of hepatitis A infection is associated with a lack of safe water and poor sanitation and hygiene (such as contaminated and dirty hands).
• A safe and effective vaccine is available to prevent hepatitis A.

Overview

Hepatitis A is an inflammation of the liver caused by the hepatitis A virus (HAV). The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the faeces of an infected person. The disease is closely associated with unsafe water or food, inadequate sanitation, poor personal hygiene and oral-anal sex.

Unlike hepatitis B and C, hepatitis A does not cause chronic liver disease but it can cause debilitating symptoms and rarely fulminant hepatitis (acute liver failure), which is often fatal. WHO estimates that in 2016, 7134 persons died from hepatitis A worldwide (accounting for 0.5% of the mortality due to viral hepatitis).

Hepatitis A occurs sporadically and in epidemics worldwide, with a tendency for cyclic recurrences. Epidemics related to contaminated food or water can erupt explosively, such as the epidemic in Shanghai in 1988 that affected about 300 000 people (1). They can also be prolonged, affecting communities for months through person-to-person transmission. Hepatitis A viruses persist in the environment and can withstand food production processes routinely used to inactivate or control bacterial pathogens.

Geographical distribution

Geographical distribution areas can be characterized as having high, intermediate or low levels of hepatitis A virus infection. However, infection does not always mean disease because infected young children do not experience any noticeable symptoms.

Infection is common in low- and middle-income countries with poor sanitary conditions and hygienic practices, and most children (90%) have been infected with the hepatitis A virus before the age of 10 years, most often without symptoms (2). Infection rates are low in high-income countries with good sanitary and hygienic conditions. Disease may occur among adolescents and adults in high-risk groups, such as persons who inject drugs (PWID), men who have sex with men (MSM), people travelling to areas of high endemicity and in isolated populations, such as closed religious groups. In the United States of America, large outbreaks have been reported among persons experiencing homelessness. In middle-income countries and regions where sanitary conditions are variable, children often escape infection in early childhood and reach adulthood without immunity.

Transmission

The hepatitis A virus is transmitted primarily by the faecal-oral route; that is when an uninfected person ingests food or water that has been contaminated with the faeces of an infected person. In families, this may happen though dirty hands when an infected person prepares food for family members. Waterborne outbreaks, though infrequent, are usually associated with sewage-contaminated or inadequately treated water.

The virus can also be transmitted through close physical contact (such as oral-anal sex) with an infectious person, although casual contact among people does not spread the virus.

Symptoms

The incubation period of hepatitis A is usually 14–28 days.

Symptoms of hepatitis A range from mild to severe and can include fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine and jaundice (a yellowing of the eyes and skin). Not everyone who is infected will have all the symptoms.

Adults have signs and symptoms of illness more often than children. The severity of disease and fatal outcomes are higher in older age groups. Infected children under 6 years of age do not usually experience noticeable symptoms, and only 10% develop jaundice. Hepatitis A sometimes relapses, meaning the person who just recovered falls sick again with another acute episode. This is normally followed by recovery.

Who is at risk?

Anyone who has not been vaccinated or previously infected can get infected with the hepatitis A virus. In areas where the virus is widespread (high endemicity), most hepatitis A infections occur during early childhood. Risk factors include:

• poor sanitation;
• lack of safe water;
• living in a household with an infected person;
• being a sexual partner of someone with acute hepatitis A infection;
• use of recreational drugs;
• sex between men; and
• travelling to areas of high endemicity without being immunized.

Diagnosis

Cases of hepatitis A are not clinically distinguishable from other types of acute viral hepatitis. Specific diagnosis is made by the detection of HAV-specific immunoglobulin G (IgM) antibodies in the blood. Additional tests include reverse transcriptase polymerase chain reaction (RT-PCR) to detect the hepatitis A virus RNA and may require specialized laboratory facilities.

Treatment

There is no specific treatment for hepatitis A. Recovery from symptoms following infection may be slow and can take several weeks or months. It is important to avoid unnecessary medications that can adversely affect the liver, e.g. acetaminophen, paracetamol.

Hospitalization is unnecessary in the absence of acute liver failure. Therapy is aimed at maintaining comfort and adequate nutritional balance, including replacement of fluids that are lost from vomiting and diarrhoea.

Prevention

Improved sanitation, food safety and immunization are the most effective ways to combat hepatitis A.

The spread of hepatitis A can be reduced by:

• adequate supplies of safe drinking water;
• proper disposal of sewage within communities; and
• personal hygiene practices such as regular handwashing before meals and after going to the bathroom.

Several injectable inactivated hepatitis A vaccines are available internationally. All provide similar protection from the virus and have comparable side effects. No vaccine is licensed for children younger than 1 year of age. In China, a live attenuated vaccine is also available.

WHO response

 

Global health sector strategies on, respectively, HIV, viral hepatitis, and sexually transmitted infections for the period 2022–2030 (GHSSs) guide the health sector in implementing strategically focused responses to achieve the goals of ending AIDS, viral hepatitis (especially chronic hepatitis B and C)  and sexually transmitted infections by 2030.

The GHSS recommend shared and disease-specific country actions supported by actions by WHO and partners. They consider the epidemiological, technological, and contextual shifts of previous years, foster learnings across the disease areas, and create opportunities to leverage innovations and new knowledge for effective responses to the diseases. They call to scale up prevention, testing and treatment of viral hepatitis with a focus to reach populations and communities most affected and at risk for each disease, as well as addressing gaps and inequities. They promote synergies under a universal health coverage and primary health care framework and contribute to achieving the goals of the 2030 Agenda for Sustainable Development.

WHO organizes annual World Hepatitis Day campaigns (as 1 of its 9 flagship annual health campaigns) to increase awareness and understanding of viral hepatitis. For World Hepatitis Day 2023, WHO focuses on the theme “One life, one liver” to illustrate the importance of the liver for a healthy life and the need to scale up viral hepatitis prevention, testing and treatment to prevent liver diseases and achieve the 2030 hepatitis elimination target.

Viral hepatitis A is an infectious disease that affects the liver, occurs in an acute form and is accompanied by short-term symptoms. Jaundice, hepatitis a, Botkin’s disease in everyday life are synonymous.

Causes of hepatitis A

The causative agent of hepatitis A is a virus that multiplies in the liver cells. More than 60% of patients are children of 3-7 years of age. The disease often takes the form of epidemic outbreaks.

How hepatitis a is contracted: this is a classic intestinal infection, so you can become infected by drinking contaminated water or food, and not observing hygiene rules.

Hepatitis A virus is excreted in the faeces of patients, as well as carriers of infection or patients with an erased form of the disease. Getting into the gastrointestinal tract of a healthy person, it penetrates through the blood into hepatocytes and destroys them. The disease proceeds only in an acute form and ends with recovery. In almost all adults, antibodies are found in the blood, indicating an infection.

It is impossible to infect a child through blood, sexual contact and from the mother.

The incidence increases in autumn and winter, and in the summer months, cases of the disease are rarely recorded. After infection, lifelong immunity remains.

Symptoms of viral hepatitis A

Acute hepatitis A occurs in stages.

• The incubation period is from 2 weeks to a month. There are no symptoms of hepatitis A, but there is already a virus in the blood and abnormal liver function is determined.
• The preicteric period lasts from 3 to 8 days. Symptoms of hepatitis a in children occur acutely: the temperature rises, intoxication occurs, severe weakness, nausea, pain in the liver, headache, sleep and stool disturbances. Children become moody and irritable. After 1 – 2 days, the temperature decreases, and the patient’s condition improves somewhat. Adults at this time may experience the same symptoms, but in a milder form.
• The icteric period lasts up to 2 weeks. At the same time, the signs of hepatitis a weaken, the state of health of most patients returns to normal. Darkening of urine and discoloration of feces, jaundice is determined. The liver is enlarged.
• The post-icteric period lasts quite a long time. At this time, there is a gradual recovery of the liver.

The convalescence period lasts up to 3 months. At this time, patients feel quite healthy, sometimes complain of fatigue, abdominal pain. In the blood, an increase in the activity of liver enzymes is periodically determined.

The course of the disease can be acute (in 95% of cases), protracted, with exacerbations, with biliary dyskinesia and other complications. Therefore, in each case, the approach to the treatment of such a patient is individual.

Diagnosis of hepatitis A

In addition to epidemiological and clinical data, diagnosis of hepatitis A includes:

• biochemical blood test to determine the activity of liver enzymes and the level of bilirubin;
• analysis for hepatitis a – detection of viral antigen by PCR or IgM class antibodies to it.

Hepatitis A treatment

Hepatitis A treatment is usually done at home. Only patients with severe forms of the disease are hospitalized. Bed rest is recommended in the first days until you feel better, then it gradually expands.

Hepatitis A diet includes:

• proteins: dairy products, lean meat and fish, scrambled eggs;
• fats: butter, olive, sunflower oil;
• carbohydrates: rice, oatmeal, buckwheat, potatoes, pasta, sugar, vegetables, juices, fruits;
• allowed salads, vinaigrette, honey, marshmallow, jam, prunes, dried apricots, raisins, bread.

Prohibited:

• pork, other fatty meats, poultry or fish;
• canned food;
• sausage;
• legumes;
• confectionery and chocolate;
• marinades and spices;
• garlic, radish, spicy cheese, mayonnaise and other foods that irritate the digestive tract.

Cholagogues, vitamins, essential phospholipids, ursosan, enterosorbents are prescribed. Antiviral drugs and antibiotics are not used.

Traditional methods of treatment:

• infusion of valerian, hawthorn and mint;
• infusion of immortelle, yarrow, wormwood and dill;
• infusion of wild rose and rowan berries;
• raw potato juice.

Hepatitis A prophylaxis

There are non-specific and specific prophylaxis for hepatitis A. Anti-epidemic measures:

• when a case of illness is detected, all contact persons are examined and their blood is taken for analysis for early detection of the epidemic;
• current and final disinfection is carried out in the focus of the disease, the quality of water and food is carefully monitored;
• In contact with the patient, prepared antibodies are administered in the form of immunoglobulin.

Immunoglobulin is not a hepatitis A vaccine, but only a measure to support the body’s defense against the virus. It is administered in the first 7 days after the diagnosis of the disease in the focus.

The only way to reliably protect a child from the virus is the hepatitis A vaccine. Domestic preparations are allowed for use, as well as the vaccines Havrix, Avaxim, Vakta, Twinrix. They are well tolerated and rarely cause adverse reactions, mainly in allergic children.

Children are vaccinated against hepatitis A at one year of age, and then again after 6 to 12 months. This scheme provides reliable immunity in 95% of those vaccinated.

Hepatitis A symptoms and treatment

Hepatitis A is a liver disease caused by the hepatitis A virus (HAV). HAV causes the liver to swell and prevent it from working properly.

HAV usually resolves spontaneously in almost all cases without serious complications. However, HAV can cause liver failure in some patients. About 100 people die of HAV every year in the United States. Those at risk for serious long-term consequences of HAV include people with other liver diseases and people over 60 years of age.

Facts in Brief

1. The incidence of hepatitis A in the United States has decreased by more than 95% since the hepatitis A vaccine became available in 1995 year.
2. Symptoms of hepatitis A usually last less than 2 months.

Information for the newly diagnosed

Who is at risk of contracting hepatitis A?

Anyone who has been in close contact with someone who has HAV, or who has eaten food or water contaminated with HAV, is at risk.

• Ever lived with an infected person
• Have ever been the sexual partner of an infected person
• Man who has sex with men
• Ever used drugs
• Ever traveled to countries where HAV is common;

HAV most commonly distributed:

• Do not wash hands before preparing or eating
• Do not wash hands after going to the toilet or changing a diaper.
• Eating raw or undercooked shellfish from sewage contaminated waters.

What are the symptoms of hepatitis A virus?

Low energy is the most common symptom of HAV. Other symptoms include fever, fatigue, loss of appetite, nausea, headache, itchy skin, muscle soreness, pain near the liver, and jaundice (yellowing of the skin and whites of the eyes).

Symptoms of HAV may appear two to seven weeks after infection and are often mild. Children may not have symptoms. Symptoms usually resolve within two months. If you think you have HAV, it’s important to see a doctor – HAV symptoms are similar to other, more serious liver diseases.

How is hepatitis A diagnosed?

Hepatitis A is diagnosed on the basis of a blood test.

A blood test is done to find out if you have antibodies to the hepatitis A virus. Antibodies are proteins created by the immune system in response to viruses.

How is hepatitis A treated?

HAV usually clears up on its own within six months.

Doctors often recommend bed rest, drinking plenty of fluids, eating a healthy diet, and avoiding alcohol. Medicines are not used to treat HAV. Talk to your doctor before taking prescription or over-the-counter medications, vitamins, or herbal supplements.

Itchy skin caused by HAV can be treated with over-the-counter anti-itch medicines.

It is important to see a doctor regularly to make sure your body is completely healed of the virus. Also talk to your doctor about hepatitis B vaccination.

What is the best way to stop the spread of hepatitis A?

Hepatitis A vaccination is the best way to prevent hepatitis A. Hepatitis A vaccine is given in two doses, usually about 2 months apart.

Other ways to stop the spread of HAV:

• Always wash your hands with soap and warm water immediately after going to the toilet or changing a diaper.
• Always wash your hands with warm soapy water before preparing or eating.

Who should be vaccinated against hepatitis A?

Those who should be vaccinated against HAV include:

• All children aged 1 year
• All children over 1 year of age living in areas where HBV is common.

Finding Clinical Trials

Clinical trials are scientific studies that test how well new medical approaches work in people. Before an experimental treatment can be tested in humans in clinical trials, it must demonstrate benefit in laboratory or animal studies. The most promising treatments are then transferred to clinical trials to identify new ways to safely and effectively prevent, screen, diagnose, or treat disease.

Talk to your doctor about the current progress and results of these trials to get the latest information about new treatments. Participation in clinical trials is a great way to help treat, prevent, and manage liver disease and its complications.
