Hepatitis A

Hepatitis A is a liver infection caused by the hepatitis A virus (HAV). HAV is highly contagious and is spread through ingesting stool infected food or drink, eating raw shellfish from polluted water, having sex with an infected induvial, or being in close contact with a infect induvial. Unlike other hepatitis viruses, HAV can only be acute and does not cause long-term liver damage. Hepatitis A causes inflammation of the liver cells and may affect how your liver works, causes symptoms. Symptoms may vary from non-existent to severe, however most are mild and only last a few weeks. In rare cases, usually in older adults, Hepatitis A can cause sudden liver failure.

Those who:

A primary shot and a booster shot that is administered six months later. The Centers for Disease Control and Prevention (CDC) recommends anyone with increased risk receive the vaccine, though there is no reason to not get the vaccine.

Symptoms of hepatitis A are usually mild, appear several weeks after infection, and usually last only a few weeks. The symptoms my include:
