Hepatitis A is a liver disease caused by the hepatitis A virus. The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the faeces of an infected person.Symptoms: The incubation period of hepatitis A is usually 14–28 days. Symptoms include fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, and dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes).
Causes: Hepatitis A usually get it when you eat or drink something that's got the virus in it. It's the least risky type because it almost always gets better on its own. It doesn't lead to long-term inflammation of your liver.
Diagnosis: Hepatitis A is not clinically distinguishable from other types of acute viral hepatitis. Specific diagnosis is made by the detection of HAV-specific IgM and IgG antibodies in the blood. Additional tests include reverse transcriptase polymerase chain reaction (RT-PCR) to detect the hepatitis A virus RNA, but may require specialised laboratory facilities.
Treatment: Therapy is aimed at maintaining comfort and adequate nutritional balance, including replacement of fluids that are lost from vomiting and diarrhoea. Statistics: The total number and rates of confirmed hepatitis A cases from 2008-2012. In Belgium the total cases reported in 2012 was 141 and out of which total were confirmed with disease. In 2011 the total cases reported was 167 and in 2010 was 137, 2009 was 130 and in 2008 it was 365.
