Transmission: hepatitis A is mainly spread through eating contaminated food or drinking contaminated water. The disease is often endemic in countries with a lack of safe water and poor sanitation.
Prevention: a vaccine exists to prevent hepatitis A. Treatment within a few weeks of exposure to the virus can also bring short term immunity. The risk of exposure can be greatly reduced by practicing good hygiene and sanitation and avoiding drinking water that has come from a potentially unsafe source.
Treatment: there is no treatment for hepatitis A. Hepatitis A only causes acute hepatitis so the body is often able to clear the infection itself within a few weeks. However, hepatitis A infection can sometimes cause further complications.
