Hepatitis A is a disease caused by a virus that has a predilection for affecting the liver and that is transmitted by oral-fecal contamination (for example, with the ingestion of food handled with unsanitized hands). As a result, it is a quite common disease in children, more characteristic of developing countries. Eventually, it can occur unnoticed in children, often manifesting as a flu-like syndrome without exuberant symptoms in adults. Complications are not common, but when they do occur, they are more common in adults. The infection is usually self-limiting, and during this period of convalescence rest, hydration, and symptomatic treatment if pain or fever are required. The infection confers long-lasting immunity against hepatitis A, but currently, for those who have not yet developed the disease, there is a vaccine available that also protects with sustained immunity against the disease.
Hepatitis A is an acute infection of the liver. It is usually a self-limiting process. However, the symptoms and progression of disease may cause significant adverse outcomes if left untreated. Vaccination is available for specific patient groups. Passive immunity does occur from pre-exposure
Hepatitis A is an infectious disease caused by the hepatitis A virus and is transmitted by fecal-oral transmission, mainly in areas with poor sanitation. The disease causes transient acute hepatitis, but the patient acquires immunity when he is cured.
