Hepatitis caused by Hepatovirus (Hepatitis A virus); it can be transmitted through fecal contamination of food or water.

INFLAMMATION of the LIVER in humans caused by a member of the HEPATOVIRUS genus, HUMAN HEPATITIS A VIRUS. It can be transmitted through fecal contamination of food or water.

Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. It can damage your liver. This swelling and damage can affect how well your liver functions. Hepatitis A is a type of viral hepatitis. It causes an acute, or short-term, infection. This means that people usually get better without treatment after a few weeks. Thanks to a vaccine, hepatitis A is not very common in the United States. Hepatitis A is caused by the hepatitis A virus. The virus spreads through contact with an infected person's stool. This can happen if you: Eat food made by someone who has the virus and did not properly wash their hands after using the bathroom; Drink contaminated water or eat foods that were rinsed with contaminated water; Have close personal contact with someone who has hepatitis A. This could be through certain types of sex (like oral-anal sex), taking care of someone who is ill, or using illegal drugs with others. Although anyone can get hepatitis A, you are at higher risk if you: Travel to developing countries; Have sex with someone who has hepatitis A; Are a man who has sex with men; Use illegal drugs; Are experiencing homelessness; Live with or care for someone who has hepatitis A; Live with or care for a child recently adopted from a country where hepatitis A is common. Not everyone with hepatitis A has symptoms. Adults are more likely to have symptoms than children. If you do have symptoms, they usually start 2 to 7 weeks after infection. They can include: Dark yellow urine; Diarrhea; Fatigue; Fever; Gray- or clay-colored stools; Joint pain; Loss of appetite; Nausea and/or vomiting; Abdominal pain; Yellowish eyes and skin, called jaundice. The symptoms usually last less than 2 months, although some people can be ill for as long as 6 months. You are at a higher risk of getting a more severe infection from hepatitis A if you also have HIV, hepatitis B, or hepatitis C. In rare cases, hepatitis A may lead to liver failure. This is more common in adults over age 50 and in people who have another liver. To diagnose hepatitis A, your health care provider may use many tools: A medical history, which includes asking about your symptoms; A physical exam; Blood tests, including tests for viral hepatitis. There is no specific treatment for hepatitis A. The best way to recover is to rest, drink plenty of liquids, and eat healthy foods. Your provider may also suggest medicines to help relieve symptoms. In more severe cases, you may need care in a hospital. The best way to prevent hepatitis A is to get the hepatitis A vaccine. It is also important to have good hygiene, especially washing your hands thoroughly after you go to the bathroom. National Institute of Diabetes and Digestive and Kidney Diseases

Hepatitis A is caused by an enterically transmitted RNA virus that, in older children and adults, causes typical symptoms of viral hepatitis, including anorexia, malaise, and jaundice. Young children may be asymptomatic. Fulminant hepatitis and death are rare in developed countries. Chronic hepatitis does not occur. Diagnosis is by...

One of the more common causes of acute hepatitis is hepatitis A virus (HAV), which was isolated by Purcell in 1973. Humans appear to be the only reservoir for this virus.

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function.

Hepatitis A virus (HAV) is an RNA virus. It is not associated with chronic liver disease. Mode of transmission is fecal-oral; therefore, it is more prevalent in environments with improper hygiene. Most infections in adults are symptomatic, whereas 70% of infections in children younger than 6 years, who are also the key reservoir for...
