Hepatitis A
Hepatitis A (HAV) is a RNA virus; it was previously called infectious hepatitis.
It is transmitted by person-to-person contact or ingestion of contaminated food or water. It is almost never through blood products.
A preventative vaccine consisting of two gamma globulin injections is available.
There is no specific treatment for HAV; however, full recovery is common.
HAV does not usually result in chronic hepatitis except in the case of newborns.
Ninety percent of newborns who contact HAV remain chronic.
A person who has HAV develops a life-long immunity.
Liver transplant is indicated only in very rare cases.
