Hepatitis A


A virus.

Epidemiologic Risks

Fecal-oral. Eat human stool, get Hepatitis A. There are often outbreaks associated with foods and restaurants and I assume all foods have a thin layer of human and/or animal stool on. As an example, there is was an outbreak from frozen Turkish pomegranate arils (PubMed).  That is why you should only eat deep fried food.




None. But there is a vaccine to prevent the disease.

Post Exposure prophylaxis: IVIG within 2 weeks of exposure. Dose is 0.02 mL/kg. The vaccine is almost as good (4.4% got Hep A) as IVIG (3.3% got Hep A) in preventing disease is given with 2 weeks (PubMed).
