Hepatitis A :
Hepatitis A Virus (HAV), is a contagious disease of the liver. The vast majority of transmissions are via ingestion of contaminated food or water, or direct contact with an infected person. It is frequently found in areas with poor sanitary conditions. Most people infected with hepatitis A get symptoms around 1 or 2 weeks after exposure which include fever, fatigue, loss of appetite, nausea, stomach pain and dark urine or discoloration of the skin. In children those signs are subtle or completely absent despite being infected with Hepatitis A. Hepatitis A infection usually does not result in serious liver damage and most people are cured without lasting effects within weeks to months. Treatment of Hepatitis A infection is mostly based on inducing rest, water therapy and following a normal diet for liver recovery. For the prevention of Hepatitis A, a vaccine is available in the form of preventive measure especially to children and travelers traveling to regions where the disease is common. Keeping good hygiene and consuming properly cooked and clean food and water is the best way to avoid being diagnosed with Hepatitis A.
