what is hepatitis ?
Hepatitis A is an enterovirus transmitted by the orofecal route, such as contaminated food. It causes an acute form of hepatitis (inflammation of the liver) and does not have a chronic stage.
The patient's immune system makes antibodies against Hepatitis A that confer immunity against future infection. A vaccine is available that will prevent infection from hepatitis A for life.
Hepatitis A is a disease affecting the liver, and caused by the Hepatitis A virus (abbreviated HAV). Only 3 out of 4 people with hepatitis A have symptoms. Those symptoms may include:
Jaundice (showing up first as yellow eyes)
Dark urine
Nausea
Fever
Fatigue
Loss of appetite
Stomach ache
Vomiting
There is no specific treatment for Hepatitis A. Sufferers are advised to rest, avoid alcohol, eat a well-balanced diet, and stay hydrated
Hepatitis A can be prevented by good hygiene and sanitation. Vaccination is also available, and is recommended in areas where the prevalence of hepatitis A is high.
Ways to prevent hepatitis A include the following:
- Wash hands with soap and warm water before preparing or eating food, and after sexual activity.
- Keep bathrooms clean and disinfected after every use.
- Cook shellfish thoroughly before eating.
- Drink water from approved sources only.
- Use a dental dam or sheet of plastic wrap during anilingus.
Hepatitis B is a diseases of the liver caused by the Hepatitis B virus (HBV), a member of the Hepadnavirus family[1] and one of several unrelated viral species which cause viral hepatitis. It was originally known as "serum hepatitis" and has caused current epidemics in parts of Asia and Africa[2].
Hepatitis B is recognized as endemic in China and various other parts of Asia[3]. Over one-third of the world's population has been or is actively infected by the virus, which results in liver inflammation, vomiting, jaundice, and death in the worst cases.
Hepatitis B is largely transmitted through exposure to bodily fluids containing the virus. This includes unprotected sexual contact, blood transfusions, re-use of contaminated needles and syringes, vertical transmission from mother to child during childbirth, and so on. The primary method of transmission depends on the prevalence of the disease in a given area. In low prevalence areas, such as the continental United States, IV drug abuse and unprotected sex are the primary methods.
There are currently several treatments for chronic hepatitis B that can increase a person's chance of clearing the infection. Treatments are available in the form of antivirals such as lamivudine and adefovir and immune system modulators such as interferon alpha. There are several other antivirals under investigation. Roughly, all of the currently available treatments, when used alone, are about equally efficacious. However, some individuals are much more likely to respond than others. It does not appear that combination therapy offers any advantages.
In general, each works by reducing the viral load by several orders of magnitude thus helping a body's immune system clear the infection. Treatment strategies should be individualized by a doctor and patient. Considerations include the risks associated with each treatment, a person's likelihood of clearing the virus with treatment, a person's risk for developing complications of persistent infection, and development of viral resistance with some of the treatments.
Several vaccines have been developed for the prevention of hepatitis B virus infection. These rely on the use of one of the viral proteins (hepatitis B surface antigen or HBsAg). The vaccine was originally prepared from plasma obtained from patients who had long-standing hepatitis B virus infection. However, currently, these are more often made using recombinant technology, though plasma-derived vaccines continue to be used; the two types of vaccines are equally effective and safe.
I must start to get immunization for all hepatitis. I wonder what type I get? hopefully not B. cannot be B.
