Hepatitis (โรคตับอักเสบ)
Hepatitis A virus (HAV) is transmitted from person to person or by ingestion of fecally contaminated food or water. Often called
infectious hepatitis, HAV usually causes mild, even subclinical infections, but rare cases of severe liver disease occur. The most significant food vehicles for HAV are shellfish, usually oysters or clams harvested from water polluted by human fecal material.
In recent years, HAV has also been transmitted in fresh produce (green onions).
