Definition of HIV and AIDS. Human Immunodeficiency Virus – (HIV) the virus that causes AIDS. Acquired Immunodeficiency Syndrome – (AIDS) a deadly disease that interferes with the body’s ability to fight infection.

What Is AIDS? Acquired means you can get infected with it. Immune Deficiency means a weakness in the body's system that fights diseases. Syndrome means a group of health problems that make up a disease

Being HIV-positive, or having HIV disease, is not the same as having AIDS. People infected with HIV have the virus for an average of 10 years before showing any symptoms of AIDS. AIDS is the late stage of having the HIV disease

You have AIDS when… A person has a CD4 cell count (a way to measure the strength of the immune system) that falls below 200. A normal CD4 cell count is 500 or higher. CD4 is another way to refer to T cells. Tcells are white blood cells that help protect the immune system by seeking out foreign infections and disease

Or When a person develops any of the specific, serious conditions – also called AIDS-defining illnesses – that are linked with HIV infection Viruses, parasites, fungi and bacteria that usually don't cause any problems for a healthy person but can make you very sick if your immune system is damaged by HIV. These are called "opportunistic infections."

How does HIV weakens the immune system?

Comparing Healthy and HIV-Infected Immune Systems Normal Response: T-cells identify virus B-cells produce antibodies, and destroy virus T-cells destroy virus that the B-cells miss, and stimulate the B-cells to produce more antibodies HIV Immune System Response: The virus seeks out and destroys T-cells. With fewer T-cells, the B-cells stop producing antibodies

What Happens if I'm HIV Positive? You might not know if you get infected by HIV. Some symptoms are: fever, headache, sore muscles and joints, stomach ache, swollen lymph glands, or a skin rash for one or two weeks. Most people think it's the flu. Some people have no symptoms. The virus will multiply in your body for a few weeks or even months before your immune system responds.

Carrier – an apparently healthy person who has HIV in the blood and can pass it to others. You can be a carrier of HIV and not have AIDS (HIV positive).

During this time, you won't test positive for HIV When your immune system responds, it starts to make antibodies. When this happens, you will test positive for HIV. You might start having signs of HIV disease like fevers, night sweats, diarrhea, or swollen lymph nodes If you have HIV disease, these problems will last more than a few days, and probably continue for several weeks.

How Can You Get HIV? You can get infected with HIV from anyone who's infected, even if they don't look sick and even if they haven't tested HIV-positive yet. HIV can pass through certain body fluids: Blood Vaginal fluid Semen Breast milk

Most people get the HIV virus by: having sex with an infected person. sharing a needle (shooting drugs) with someone who's infected being born when their mother is infected (With no treatment, about 25% of the babies of HIV-infected women would be born infected.), or drinking the breast milk of an infected woman. Getting a transfusion of infected blood used to be a way people got AIDS, but now the blood supply is screened very carefully and the risk is extremely low

There are no documented cases of HIV being transmitted by tears or saliva, but it is possible to be infected with HIV through oral sex or in rare cases through deep kissing. Why?

To decrease the risk of spreading HIV: Use condoms during sexual activity; Do not share drug injection equipment If you are HIV-infected and pregnant, talk with your doctor about taking anti-HIV drugs If you are an HIV-infected woman, don't breast feed any baby Protect cuts, open sores, and your eyes and mouth from contact with blood

Signs of AIDS: Low T-cell count Kaposi’s Sarcoma – form of cancer Pneumocystic pneumonia AIDS-related diseases also include: Serious weight loss Brain tumors Without treatment, these opportunistic infections can kill you

Where did HIV/AIDS come from? In 1999 scientists were able to trace the virus back to a subspecies of chimpanzees native to west Africa as the original source of the virus. The researchers believe that HIV-1 was introduced into the human population when hunters became exposed to infected blood.

How could HIV have crossed species? It has been known for a long time that certain viruses can pass from animals to humans. Some other rather controversial theories have contended that HIV was transferred through medical experiments.

The first cases of AIDS in the United States were reported in 1981 The first cases of AIDS in the United States were reported in 1981. There is no cure for AIDS, and no vaccine against HIV.

Life expectancy AIDS is different in every infected person. Some people die in a few months after getting infected, while others live fairly normal lives for many years, even after they "officially" have AIDS A few HIV-positive people stay healthy for many years even without taking anti-HIV medications

A blood test can tell you if you are infected with HIV A blood test can tell you if you are infected with HIV. However, it may take 6 months after infection before antibodies show up in the blood. AZT – a drug that delays the onset of AIDS symptoms in some patients, but has serious side effects.

Common myths about how HIV is spread. through the air; either breathing the same air as an infected person, or from a sneeze or cough closed-mouth kissing through casual contact; hugging or shaking hands

Other myths about how HIV is spread: through mosquitoes sharing eating utensils donating blood

EDUCATION is the key to preventing the spread of AIDS.
