What is Hepatitis A?
Hepatitis A
is a contagious virus that can cause liver disease. It causes an acute, or
short-term, infection. This means that
people usually get better without treatment after a few weeks. In rare cases,
particularly for people with a pre-existing health condition or people with
weakened immune systems, hepatitis A infections can progress to liver failure
and death.
What causes hepatitis A?
Hepatitis A
is caused by the hepatitis A virus. The virus spreads through contact with an
infected person's stool.
Here are some of the specific ways the hepatitis A virus can spread:
·
Drink contaminated
water or eat foods that were rinsed with contaminated water.
·
Having sex with
someone who has the virus
Laboratory diagnosis of hepatitis A:
The
diagnostic gold standard for hepatitis A is the detection of anti-hepatitis A
virus (HAV) IgM antibodies and the determination of total anti-HAV by enzyme
immunoassay.
However,
detection of HAV RNA can be useful in the diagnosis of patients without
specific antibodies for hepatitis A and for the monitoring of infection.
Studies
using real-time PCR have demonstrated that HAV RNA can be detected not only in
feces, but also in serum and saliva samples earlier than detection of
antibodies of hepatitis A.
