WHAT IS HEPATITIS A?

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. It is a vaccine-preventable illness that is easily spread through close contact, as well as from sharing injection and non-injection drugs.

Hepatitis A usually spreads when a person unknowingly ingests the virus from objects, food or drinks contaminated by small, undetected amounts of stool (feces) from an infected person. Hepatitis A can also spread from close personal contact with an infected person such as through sex or caring for someone who is ill.

An infected person can transmit the virus to others up to two weeks before symptoms appear, and even those who do not experience symptoms can transmit the virus to others.

HEPATITIS A PREVENTION

The best way to prevent hepatitis A is through vaccination with the hepatitis A vaccine (see below for Advisory Committee on Immunization Practices [ACIP] recommendations). Unvaccinated people who have been exposed recently (within two weeks) to the hepatitis A virus should get the hepatitis A vaccine or a shot of immune globulin to prevent severe illness.

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.

WHAT ARE THE SYMPTOMS OF HEPATITIS A?

Symptoms include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain and jaundice (yellowing of the skin and eyes).

Most children younger than age 6 do not have symptoms when they have hepatitis A. If symptoms occur, they usually appear four weeks after exposure, but can occur as early as two weeks and as late as seven weeks after exposure.

Symptoms usually develop over a period of several days and last less than two months, although a small percentage of people (10-15 percent) can have symptoms for as long as six months.

Sometimes hepatitis A can cause liver failure and death, although this is rare and occurs more commonly in people older than 50 and people with other liver diseases.
