HAV is a virus that causes acute inflammation of the liver. HAV infection results in lifelong immunity to further infections. HAV does not lead to chronic disease. Per the CDC, 33% of American citizens have been infected with HAV.
HAV is transmitted by the fecal/oral route by ingestion of fecal contaminated food and water, or through close personal contact with an infected person. HAV can remain infectious for up to 10 months in water. For this reason all shellfish should be thoroughly cooked.
Symptoms vary from no symptoms to light stools, dark urine, fatigue, fever and jaundice. Symptoms usually last less than (2) months.
A blood test is available. Check with your physician if you suspect that you may have hepatitis of any form.
Prevention through vaccination is the best strategy. Immune globulin can be administered for short term protection.
Household contacts can be protected through vaccination. Wash hands after going to the toilet. Clean surfaces contaminated with feces
