Hepatitis A (infectious hepatitis, HVA), Also known as infectious hepatitis, can cause acute liver disease. In most cases, however, the liver heals within a few months.
Hepatitis A can develop without sudden signs or symptoms. It is easily spread through person-to-person contact, fecal contamination of food or water, and raw shellfish taken from polluted water. It is contagious between two to three weeks before, and one week after jaundice appears.
Transmitted by contaminated water, milk, or food, it has an incubation period of 15-45 days. The contagion is highest just before illness begins; so food workers can transmit the disease. Hepatitis A is contagious between one to two weeks before illness start. It is easily spread by person-to- person contact, and through food, clothing, linens, etc. It can be transmitted from animals, eating shellfish is a good way to get it, even if the waters they live in pass national standards. Recovery generally occurs within 4 weeks. Chronic cases are less likely to occur.
