  "field": "Environment",
  "definition": "1. Acute inflammation of the liver caused by the hepatitis A virus. It is highly contagious and usually contracted through close contact with an infected individual or their feces, contaminated food or water.\n\n2. Hepatitis caused by hepatovirus. It can be transmitted through fecal contamination of food or water. (MSH2003_2003_05_12)\n\n3. The term hepatitis A (HA) or type A viral hepatitis has replaced all previous designations: infectious hepatitis, epidemic hepatitis, epidemic jaundice, catarrhal jaundice, infectious icterus, Botkins disease, and MS-1 hepatitis. Hepatitis A is usually a mild illness characterized by sudden onset of fever, malaise, nausea, anorexia, and abdominal discomfort, followed in several days by jaundice. The infectious dose is unknown but presumably is 10-100 virus particles.HAV is primarilly transmitted by person-to-person contact through fecal contamination, but common-source epidemics from contaminated food and water also occur. Poor sanitation and crowding facilitate transmission. Outbreaks of HA are common in institutions, crowded house projects, and prisons and in military forces in adverse situations.",
