What is HIV and what is AIDS?
*Human Immunodeficiency Virus (HIV) is an infectious
disease that can lead to Acquired Immune Deficiency Syndrome (AIDS). HIV
causes a breakdown of the immune system resulting in a loss in the ability
to resist infections and disease. As HIV progresses, the body's immune
system weakens and infections and/or diseases appear until the infected
person's condition satisfies the case definition of AIDS.
How
did AIDS get its name?
In 1982, CDC officially adopted the name, acquired
immune deficiency syndrome (AIDS),
After meeting with groups composed of persons with hemophilia, blood industry
Officials, gay community organizations, and assorted leaders from CDC,
the National
Institutes of Health and the Food and Drug Administration.
The Difference Between HIV and AIDS
*HIV stands for the Human Immunodeficiency
Virus. Let's take a closer look at these words and what they mean:
*"H" is for Human, meaning that
only humans get this virus. That's another way of saying that the virus
is "species specific." So you don't have to worry about ever
getting infected from a pet or a mosquito
*"I" is for Immunodeficiency, meaning
that this virus causes your immune system to have some serious problems.
The immune system is what fights off diseases and infections. When your
immune system starts to have problems, it makes it easier for you to get
sick and harder for you to get well.
*"V" is for Virus, which refers
to the specific type of germ or antigen. Other types of germs are bacteria,
fungi, and parasites. Fortunately, all of those types of germs can be
killed with specific medications. Unfortunately, viruses can't be killed.
You can't take a medicine like an antibiotic and get rid of HIV. Viruses
stay with us forever. Sometimes we are able to create conditions where
they don't cause us any problems, and that is where a strong and healthy
immune system comes in handy.
*
AIDS stands for Acquired Immune Deficiency
Syndrome. It is the result of a weakened immune system caused by HIV infection.
AIDS is diagnosed when a person tests positive for HIV and also has one
or more of the "opportunistic infections" of AIDS (there are
27) and/or has a laboratory marker test of 200 or fewer T-cells. AIDS
should be diagnosed by a physician. The opportunistic infections associated
with AIDS are called "AIDS-defining illnesses" and should also
be diagnosed by a physician.
*Both HIV infection and AIDS are considered to be chronic illnesses managed
with both pharmaceutical (pharmacy drugs) therapies and complementary
(alternative) therapies. In most cases, people can live for many years
with HIV infection and with AIDS. It is usually impossible to know just
how long a person will live with AIDS. Today's HIV therapies are extending
the lives of Persons Living With AIDS as well as helping to improve their
quality of life.
