World AIDS Day, observed December 1 each year, is dedicated to raising HIV/AIDS awareness.

It is common to hold memorials to honor persons who have died from HIV/AIDS on this day. Government and health officials also observe the event, often with speeches about AIDS topics. Since 1995, the President of the United States has made an official proclamation on World AIDS Day.

AIDS has killed more than 25 million people between 1981 and 2007, and an estimated 33.2 million people worldwide live with HIV as of 2007. Despite recent, improved access to treatment and care in many regions of the world, the AIDS epidemic claimed an estimated 2 million lives in 2007, of which about 270,000 were children.

For the past few years, I've included lessons about HIV/AIDS in my classes to improve understanding of this serious issue. There is still a lot of misinformation out there. Many people are still not clear about how you can or can't get the virus or what it means when someone has it.

HIV/AIDS is not a gay disease. Anyone can get it, so it's important to get the information and know how to protect yourself.

It's not easy to get HIV:

• You cannot get it from touching, hugging or even kissing someone who has it (unless you both are bleeding in the spots where you touch).
• You cannot get it from sharing drinking glasses or toilets.
• You will not get it from a mosquito bite.
• You cannot tell if someone has it just by looking at them.

It's a difficult, and often embarrassing subject to discuss, but lives depend on having this discussion. I hope that this post will provide some basic information and maybe motivate you to research and learn more.

Always remember:

When you play, play safe! (use condoms)

HIV and AIDS

Many people (not just kids, but adults, too) don't really understand how HIV and AIDS are related, even though they hear these two words used together all the time.

HIV stands for human immunodeficiency virus. AIDS stands for acquired immunodeficiency syndrome. HIV is actually the virus that causes the disease AIDS.

HIV Hurts the Immune System

People who are HIV positive have been tested and found to have signs of the virus in their blood. HIV destroys part of the immune  system. Specifically, it affects a type of white blood cell called the T lymphocyte , or T cell. T cells are one type of "fighter" cell in the blood that help the body fight off all kinds of germs and diseases.

After HIV enters the body, it piggybacks onto a T cell and works its way inside that cell. Once inside, the virus completely takes over the T cell and uses it as a virus-making factory to make a lot of copies of itself. The newly made viruses then leave the T cell and go on to infect and destroy other healthy T cells as they continue to multiply inside the body. After the virus invades the T cells, they can no longer properly fight infections.

Someone who is infected with the virus is called "HIV positive".  But it may take years for the virus to damage enough T cells for that person to get sick and develop AIDS. Thanks to new medications, someone infected with HIV can stay relatively healthy and symptom-free for many years. But these medications are very expensive and not available to everyone in the world.

Although the HIV-positive person may feel fine, the virus is silently reproducing itself and destroying T cells. And during this time, the person is still contagious , which means he or she is able to give the disease to others.

When the person's immune system has weakened and more of the blood's T cells have been destroyed by the virus, the person can no longer fight off infections. This is when he or she gets very sick. A doctor diagnoses a person with AIDS when the person has a very low number of T cells and shows signs of a serious infection.

How Many People Have HIV and AIDS?

Since the discovery of the virus more than 20 years ago, millions of people throughout the world have been infected with HIV. Most are adults, but there are kids and teens who have HIV, too. In the world today, AIDS remains an epidemic , which means that it affects a large number of people and continues to spread rapidly.

Right now, about 40 million people in the world are living with HIV infection or AIDS. This estimate includes 37 million adults and 2.5 million children. In the United States alone, more than 1 million people are living with HIV.

How Is HIV Spread?

HIV infection isn't like a cold or the flu. A person cannot get HIV by hugging or holding the hand of, sharing a school bus or classroom with, or visiting the home of someone who has HIV. HIV is passed only through direct contact with another person's body fluids, such as blood. The majority of people in North America get infected with HIV by:

• having sexual contact with a person who has HIV
• sharing needles or syringes (used to inject illegal drugs) with a person who has HIV

Other ways of getting HIV can occur when:

• an infected pregnant woman passes it to her unborn child
• a person has a blood transfusion. But in North America today, all donated blood is tested for HIV, so the risk of getting HIV is less than 1 in a million.

What Are the Symptoms of HIV and AIDS?

Most people don't feel any different after they are infected with HIV. In fact, infected people often do not experience symptoms for years. Some people develop flu-like symptoms a few days to a few weeks after being infected, but these symptoms usually go away after several days.

An HIV-positive person will eventually begin to feel sick. The person might begin to have swollen lymph nodes, weight loss, fevers that come and go, infections in the mouth, diarrhea, or he or she might feel tired for no reason all of the time. Eventually, the virus can infect all of the body's organs, including the brain, making it hard for the person to think and remember things.

When a person's T cell count gets very low, the immune system is so weak that many different diseases and infections by other germs can develop. These can be life threatening. For example, people with AIDS often develop pneumonia , which causes bad coughing and breathing problems. Other infections can affect the eyes, the organs of the digestive system, the kidneys, the lungs, and the brain. Some people develop rare kinds of cancers of the skin or immune system.

Most of the children who have HIV got it because their mothers were infected and passed the virus to them before they were born. Babies born with HIV infection may not show any symptoms at first, but the progression of AIDS is often faster in babies than in adults. Doctors need to watch them closely. Kids who have HIV or AIDS learn more slowly than healthy kids and tend to start walking and talking later.

How Are HIV and AIDS Diagnosed?

A person can be infected with HIV without even knowing it. So doctors recommend that anyone who thinks he or she may have been exposed to the virus get tested - even if the chance of having been infected seems small. Doctors test a person's blood to find out if he or she is infected with HIV.

People who are HIV positive need to have more blood tests every so often. The doctor will want to check on how many T cells the person has. The lower the T cell count, the weaker the immune system and the greater the risk that someone will get very sick.

How Are HIV and AIDS Treated?

Right now there is no cure for HIV or AIDS, but new medicines can help people live longer lives. Scientists are also researching vaccines that may one day help to prevent HIV infection, but it's a very tough assignment, and no one knows when these vaccines might become available. It's up to everyone to prevent AIDS by avoiding the behaviors that lead to HIV infection.

Can HIV and AIDS Be Prevented?

People can help stop the spread of HIV by avoiding sexual contact with infected people and by not sharing needles or syringes.

Health care workers (such as doctors, nurses, and dentists) help prevent the spread of HIV by wearing plastic gloves when working on a patient. Hospitals have strict procedures for handling samples of blood and other body fluids to prevent others from coming in contact with HIV.

Living With HIV and AIDS

New drugs make it possible for people who are HIV positive to live for years without getting AIDS. They can work or go to school, make friends, hang out, and do most of the things other people can do. They will have to take certain medicines every day and see their doctors pretty often, and they may get sick more than other people do because their immune systems are more fragile.

Even though they may look OK, people who are HIV positive may sometimes feel scared, angry, unhappy, or depressed. They may feel afraid that the people at work or school could find out and start treating them differently. It is important for all of us to remember that usual social contact, like eating lunch or playing games, with people who are HIV positive does not bring any risk of infection.

When HIV infection gets worse or turns into the disease called AIDS, life really changes. The person may need to spend a lot of time in bed or in the hospital because of serious illnesses. He or she may feel very tired or weak most of the time. The person also might lose weight.

Hope for an HIV-Free Future

Maybe one day, with time and research, a cure for HIV infection will be found and AIDS will no longer exist. Until then, the smartest thing to do is to know the facts and not put yourself at risk.

If you have more questions about HIV or AIDS, talk to an adult you trust - a parent, doctor, school nurse, or guidance counselor. Don't depend only on your friends for information about HIV and AIDS because they may not know all the right answers.
