Map of Hepatitis A
Hepatitis A is a virus that causes hepatic disease Hepatitis A, an inflammation that gives jaundice. Hepatitis A is highly contagious and is present in the intestine of infected people and spread through the stools. Therefore, there may be sewage.
Foods can either be polluted by contaminated water or if it has been handled by an infected person. Viruses can not propagate in food, but it is also not necessary because no more than 10-100 virus particles are needed to get sick.
Common sources of infection are foods that are manufactured under poor hygiene conditions that need not be heated before eaten, for example, mussels and oysters, lettuce, frozen berries and tap water not treated and controlled.
The virus can also be spread from person to person. SymptomsThe first symptoms of Hepatitis A are fever, fatigue, stomach pains, nausea and vomiting . After a few days, skin and eyelashes may turn yellow, urine dark and feces lighter than normal. Anyone who is ill will not get yellow, but most people suffer from fatigue and may have poor appetite for weeks to months. Hepatitis A is usually normalized by itself and most are healthy after about two months. Small children infected with Hepatitis A rarely have disease symptoms and can therefore contribute to a large spread of the disease in countries where the virus is common.
