Hepatitis B Infections
Will I feel sick when I am first infected with hepatitis
Hepatitis B is considered a "silent infection" because
most people don't have symptoms when they are first infected.
People can get hepatitis B without even knowing it. Some who
are infected may have mild flu-like symptoms which are often
ignored -- they think they just have a cold and then get better
quickly. Others may go to a doctor because they feel more tired
than usual, don't feel like eating, have an upset stomach, or
complain about joint pain. Although severe symptoms are not common
with a new hepatitis B infection, they could include a swollen
stomach or eyes and skin turning yellow (this is called "jaundice").
See your doctor for any unusual symptoms or even if you just
What blood test should I ask my doctor to order?
Make sure that your doctor orders the hepatitis B blood tests.
This is a simple test that can be done in a doctor's office.
If you think you have been recently infected with hepatitis
B, it will take 4 -6 weeks before a blood test will show positive
for the virus. Ask for a written copy of your blood tests.
Make sure your doctor clearly explains your blood test results
so that you know whether you have hepatitis B or not. You need
to know whether you have recovered or whether you have become
chronically infected. Your doctor may check your blood several
times to confirm your diagnosis.
Where can I go to be tested?
You can ask your family doctor, the local health department,
or a liver specialist to order the simple hepatitis B blood
test. This blood test can be done in any doctor's office.
You can also call the GlaxoSmithKline HBV Info and Assistance
line, toll-free at 1-888-888-0981. Information about HBV
and physician referrals across the country are available in English,
Mandarin, Cantonese, Korean, and Vietnamese.
What will happen if I get infected with hepatitis B?
After a person is first infected with hepatitis B, there are
usually three things that can happen:
- Recovery - 90% of healthy adults who are
infected will "recover" and be completely rid of
the virus within six months. When a blood test shows that the
hepatitis B virus has gone and that "antibodies" have
been made, a person is then considered to have recovered. They
are no longer contagious to others. The "antibodies" protect
them from any future hepatitis B infections. These people do
not need the vaccine since they are already protected.
- Chronic Infections - 10% of infected adults
are unable to get rid of the virus after six months. They are
diagnosed as being "chronic carriers" of hepatitis
B. This means that the virus stays in their blood and liver.
People who are "chronic carriers" of hepatitis B
are able to pass the virus on to others through their blood.
They may also develop serious liver disease later on.
- Acute Liver Failure - Less than 1% of infected
adults can have a severe reaction and die from liver failure
within several weeks after being exposed to the hepatitis B
virus. Liver failure is life-threatening and a person must
get immediate medical care. This is a very rare reaction.
What do all these numbers really mean?
Imagine you are sitting in a room. There are 100 people in this
room, including yourself. The door opens and the hepatitis
B virus walks in and infects everyone. You all go home. Some
people may feel sick a couple weeks later, most of you will
not. Six months later everyone is asked to return to the room
for a simple hepatitis B blood test. The good news is that
90 people will have gotten rid of the virus and "recovered".
They can go home. But 10 people (maybe including you?) have
been unable to get rid of the virus. These 10 people are then
diagnosed as "chronic carriers". They are told to
be careful to avoid infecting others, to test and vaccinate
their loved ones, and to find a doctor who can provide good
medical care. Although this is rare, one person may have an
immediate severe reaction to the hepatitis B virus and die
several weeks later from liver failure.
What happens to babies and children who are infected
with hepatitis B?
Unfortunately, babies and children have a lot more trouble getting
rid of the virus after being infected. Their immune systems are
too young to fight off the virus. So they are at much greater
risk for becoming "chronic carriers" of hepatitis B.
The virus will stay in their blood and liver for a long time,
which increases their risk for serious liver disease later on.
- Recovery - Babies under one year have a
5-10% chance of getting rid of the virus and "recovering".
Children have a 40% chance of getting rid of the virus (whereas,
adults have a 90% chance of recovering).
- Chronic Infections - 90% of infected babies
will never get rid of the virus and will become "chronic
carriers" of hepatitis B -- the virus will stay in their
bodies for a very long time. Children have a 60% chance of
becoming "chronic carriers (whereas, adults have only
a 10% chance of becoming chronically infected).
How will I know if I have "recovered" from
a hepatitis B infection?
A person is considered to have "recovered" when blood
tests show they have gotten rid of the virus. In addition, the
test must show that their immune system has made a "surface
antibody" against the virus. The "surface antibody" is
what protects you from hepatitis B in the future. Until you recover,
which can take up to six months, there is still a risk that you
can spread the virus. Once you have recovered, then you can no
longer infect others. Ask your doctor for this simple blood test.
Do I still the need the hepatitis B vaccine after I
You do not need the vaccine if your blood tests show that you
have recovered. The "surface antibody" that your immune
system makes will protect you against any future hepatitis B
infection. It works just like chicken pox: when you get chicken
pox and recover, your body has successfully made antibodies to
protect you from getting chicken pox again.
What does it mean if my doctor tells me that I'm a "chronic
This means that you have been unable to get rid of the hepatitis
B virus. You have become a "chronic carrier" of the
virus. For some reason your immune system just can't fight off
the hepatitis B virus. It can stay in your blood and liver for
a long time. As a result, you can pass the virus on to others.
You also live with an increased risk for serious liver disease
later in life.
Are there any treatments if I have chronic hepatitis
Currently, there are seven approved drugs in the
United States for people who have chronic hepatitis B infections.
These drugs are also available in China:
- Interferon Alpha (Intron A) is given by injection several times a week for six months to a year, or sometimes longer. The drug can cause side effects such as flu-like symptoms, depression, and headaches. Approved 1991 and available for both children and adults.
- Pegylated Interferon (Pegasys) is given by injection once a week usually for six months to a year. The drug can cause side effects such as flu-like symptoms and depression. Approved May 2005 and available only for adults.
- Lamivudine (Epivir-HBV, Zeffix, or Heptodin) is a pill that is taken once a day, with few side effects, for at least one year or longer. Approved 1998 and available for both children and adults.
- Adefovir Dipivoxil (Hepsera) is a pill taken once a day, with few side effects, for at least one year or longer. Approved September 2002 for adults. Pediatric clinical trials are in progress.
- Entecavir (Baraclude) is a pill taken once a day, with few side effects, for at least one year or longer. Approved April 2005 for adults. Pediatric clinical trials are in progress.
- Telbivudine (Tyzeka, Sebivo) is a pill taken once a day, with few side effects, for at least one year or longer. Approved October 2006 for adults.
- Tenofovir (Viread) is a pill taken once a day, with few side effects, for at least one year or longer. Approved August 2008 for adults.
It is important to know, not every chronic hepatitis B patient
needs to be on medication. Some patients only need to be monitored
by their doctor on a regular basis (at least once a year, or
more). Other patients with active signs of liver disease may
benefit the most from treatment. Be sure to talk to your doctor
about whether you could benefit from treatment and discuss the
treatment options. In addition, there are promising new drugs
in clinical trials and in the research pipeline.
However, it is vital that all people with chronic hepatitis
B visit their doctor on a regular basis, whether they receive
treatment or not!
