Hepatitis A – HAV – Pathogenesis, Epidemiology, Caces and Diagnosis

Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus (HAV), which is most commonly transmitted by the fecal-oral route via contaminated food or drinking water. Every year, approximately 10 million people worldwide are infected with the virus. The time between infection and the appearance of the symptoms, (the incubation period), is between two and six weeks and the average incubation period is 28 days.

In developing countries, and in regions with poor hygiene standards, the incidence of infection with this virus is high and the illness is usually contracted in early childhood. HAV has also been found in samples taken to study ocean water quality. Hepatitis A infection causes no clinical signs and symptoms in over 90% of these children and since the infection confers lifelong immunity, the disease is of no special significance to the indigenous population. In Europe, the United States and other industrialized countries, on the other hand, the infection is contracted primarily by susceptible young adults, most of whom are infected with the virus during trips to countries with a high incidence of the disease.

Hepatitis – Causes, Symptoms, Types, Prevention and Treatment

Hepatitis is the presence of inflammatory cells in the liver tissue caused by excessive alcohol drinking, disorders of the gall bladder or pancreas, including medication side effects, and infections. In this article, we will discuss Causes, Symptoms, Types, Prevention and Treatment of hepatitis.

I. Causes of hepatitis

A person can develop hepatitis if they contract one of the viruses that can cause liver inflammation, or as a result of exposure to substances that can cause hepatitis. There are two ways that can lead to hepatitis: it can either occur as a result of infections or from autoimmune processes.
