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 a virus often causes hepatitis. In the United States, the most common hepatitis viruses are hepatitis A virus, hepatitis B virus, and hepatitis C virus.
What is hepatitis A?
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. It can range from a mild illness lasting a few weeks to a severe illness lasting several months. Although rare, hepatitis A can cause death in some people. Hepatitis A usually spreads when a person unknowingly ingests the virus from objects, food, or drinks contaminated by small, undetected amounts of stool from an infected person.
How serious is hepatitis A?
Most people who get hepatitis A feel sick for several weeks, but they usually recover completely and do not have lasting liver damage. In rare cases, hepatitis A can cause liver failure and death; this is more common in people older than 50 and in people with other liver diseases.
How common is hepatitis A in the United States?
In 2016, there were an estimated 4,000 hepatitis A cases in the United States. Hepatitis A rates have declined by more than 95% since the hepatitis A vaccine first became available in 1995.
Can hepatitis A be prevented?
Yes. 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.
How is the hepatitis A vaccine given?
The hepatitis A vaccine is safe and effective and given as 2 shots, 6 months apart. Both shots are needed for long-term protection.Credit to www.cdc.gov/hepatitis/hav/afaq.htm
