When Your Child Has Hepatitis A Virus (HAV) Infection
Hepatitis is an inflammation of the liver. Many things can cause it. One cause is infection with the hepatitis A virus (HAV). This virus can spread through food or water. It can also spread from person to person through infected stool. For example, it spreads if a person doesn’t wash his or her hands after using the bathroom or changing a dirty diaper. HAV often spreads in daycare, restaurants, and places with poor sewage treatment. In most cases, the virus doesn’t make children very sick. It may cause symptoms like the flu. But it likely won’t cause long-term problems.
Symptoms of hepatitis A infection
Symptoms usually appear about 2 to 6 weeks after contact with the virus. Symptoms are often mild in children. They can include:
Pain in the upper right abdomen, where the liver is
Tiredness and weakness
Sore muscles and joints
Nausea, vomiting, or diarrhea
Yellowing of the skin and whites of the eyes, dark urine, or light-colored stools (jaundice)
Treatment for hepatitis A infection
Hepatitis A goes away on its own. It may take several weeks or months. Symptoms are treated to make your child comfortable. Make sure to:
Make sure your child gets plenty of rest.
Give your child plenty of fluids. This is to help prevent dehydration. Good choices are water or an electrolyte drink for children. Moderate amounts of fruit juice are also OK.
Check with your child’s healthcare provider before giving your child any medicines from the drug store. The liver processes all medicines. A child with hepatitis A may not be able to take certain medicines.
Preventing hepatitis A from spreading
A child with hepatitis A can spread the virus to others, even before symptoms appear. He or she can still spread the virus for a few days after symptoms start. Keep your sick child home from school or daycare until symptoms are gone.
Good handwashing helps prevent the spread of hepatitis A. Adults and children should wash hands often, and always after using the bathroom or changing diapers. Adults and children should also wash hands before preparing food or eating. To wash your hands or your child’s hands, work up a good lather with soap and warm water. Scrub for at least 10 to 15 seconds, then rinse.
You should also have your child and others in the household vaccinated against viral hepatitis. The hepatitis A vaccine is safe for any adult or child over age 1. Once a child has hepatitis A, he or she can’t get it again. But your child could get another type of hepatitis. And getting vaccinated soon after exposure to HAV could prevent illness. Members of the household should be vaccinated against hepatitis A and B (another type of hepatitis virus), if they haven’t been already. There is no vaccine for hepatitis C or the other less common types of hepatitis.
In rare cases, hepatitis A can lead to a serious infection and liver failure. If a child has another liver problem, hepatitis A could make it worse. In most cases, though, hepatitis A does not cause any lasting problems in children.
When to call the healthcare provider
Call the healthcare provider if your child has signs of a more serious problem, such as:
Dehydration, which can show up as less urine, very dark urine, dry mouth, no tears when crying
Extreme irritability or drowsiness
Loss of consciousness
Swelling in the hands, arms, feet, ankles, abdomen, or face
Bleeding from the nose, mouth, or rectum
