About Hepatitis A

Hepatitis A is caused by the hepatitis A virus, and it can cause damage to the liver and other health problems. Hepatitis A can range from a mild illness lasting a few weeks to a serious illness lasting several months.

Symptoms of hepatitis A include:

  • Fatigue
  • Poor appetite
  • Stomach pain or tenderness
  • Nausea or vomiting
  • Dark urine
  • Yellowing of the skin (jaundice). 

Most children less than 6 years do not experience symptoms. Symptoms typically appear 2 to 6 weeks after exposure. Individuals with symptoms should call their provider or seek care.

How is it spread?

The virus is found in the feces (poop) of people with hepatitis A. Most infections result from contact with an infected household member or sex partners. The virus can also be spread by consuming food or drink that has been handled by someone with hepatitis A. Someone who has hepatitis A can spread it to others for up to 2 weeks before symptoms appear.

Prevention

The best way to prevent hepatitis A is to get vaccinated. Since 2006, the hepatitis A vaccine has been routinely recommended for children. But, the majority of local adults are not vaccinated.

Frequent handwashing with soap and warm water after using the bathroom and before handling food can also help prevent the spread of hepatitis A.
