1. Treatment for HIV and AIDS
Do you think HIV is a curable disease?
Even though medicines can slow the progress of HIV infection, there is still no vaccine that prevents the disease.

2. In this lesson, you will learn to:
Lesson Objectives
In this lesson, you will learn to:
Examine how technology has impacted the health of persons with HIV
Identify world and community health services available for people living with HIV/AIDS
Develop refusal skills and ways to avoid unsafe situations

3. Stages of HIV Infection
How HIV Develops
A person is considered infectious immediately after contracting the virus.
Approximately half of all persons develop symptoms such as fever, rash, headache, body aches, and swollen glands about three to six weeks after becoming infected with HIV.
These symptoms disappear within a week to a month and the person enters the asymptomatic stage.
A person may show no signs of illness for 6 months to 10 years or more, though the viruses continue to grow and the infected person can still transmit the virus to others.

4. Stages of HIV Infection
Symptomatic HIV Infection
During the asymptomatic stage, the immune system keeps pace with HIV infection by producing billions of new cells.
Eventually the numbers of cells in the immune system decline to the point where other infections start to take over, and this marks the symptomatic stage.
The symptoms may include swollen glands, weight loss, and yeast infections.

5. Stages of HIV Infection
AIDS
During the latter stage of HIV infection, more serious symptoms appear until the infection meets the official definition of AIDS.
These symptoms include the presence of HIV infection, a severely damaged immune system measured by numbers of helper T cells, and the appearance of one or more opportunistic infections or illnesses.
By the time AIDS develops, HIV has often attacked brain cells, causing difficulty in thinking and remembering.

6. Detecting HIV
EIA Test
The first test usually performed is an ELISA, or EIA.
The EIA may give inaccurate results for two reasons:
Developing antibodies takes time.
Certain health conditions such as hemophilia, hepatitis, and pregnancy.

7. Developing Antibodies Takes Time
Detecting HIV
Developing Antibodies Takes Time
Developing antibodies takes weeks or even months after initial infection.
Before antibodies develop, the EIA may give a false negative result.
This result means the test is negative, but the person is positive.
Most people will test positive in three to four weeks, but some people take up to six months to test positive.

8. Certain Health Conditions
Detecting HIV
Certain Health Conditions
Health conditions such as hemophilia, hepatitis, and pregnancy can cause the EIA to give a false positive reading.
This means that although the test was positive, the person actually does not have the infection.

9. Western Blot Test Detecting HIV
If the EIA test is positive, it can be repeated to make sure the results are accurate.
If the repeat test is also positive, other confirmation tests, such as the Western blot (WB) test, will be done.
If done properly, this test is 100 percent accurate.
If the results of all three of these tests are positive, a person is determined to have HIV.

10. The Impact of the Availability of Health Services
Difficulties with Treating HIV
None of the drugs and vaccines being researched cure HIV/AIDS because HIV infects the very cells that regulate the immune response.
Several new strains of the virus have emerged since it was first discovered, making it even harder to develop an effective treatment.
Some people stop treatment or take medicines only once in a while due to severe side effects, which can lead to the development of new, drug-resistant strains of the virus.
Treatment can be costly, exceeding $1,000 a month.

11. HIV/AIDS—A Continuing Problem
Drug-Resistant Strains of HIV
Much of the decrease in AIDS cases results from the success of drug cocktails—combinations of drugs—that slow the progression of HIV infection.
This success has brought a false security about the need for HIV prevention.
However, research has identified new, drug-resistant strains of HIV.
The combination of drug resistance and high-risk behaviors could result in HIV strains that are transmitted and spread even more widely.

12. HIV/AIDS—A Continuing Problem
HIV/AIDS: The Global Picture
At the end of 2002, an estimated 40 million people worldwide were infected with HIV/AIDS.
This statistic means that HIV is now pandemic.
The number of people living with HIV is growing.

13. HIV/AIDS—A Continuing Problem
Staying Informed About HIV/AIDS
Knowledge is the first defense against infection from HIV.
New research can be found in newspapers and magazines and on television, radio, and the Internet.
The CDC, state health departments, and community health services are excellent sources of information.
Teachers, school counselors, and physicians can provide guidance on how to find information.

14. HIV/AIDS—A Continuing Problem
Abstinence and HIV/AIDS
During your teen years, you may feel pressure to experiment with new behaviors, such as engaging in sexual activity or using drugs.
Consider that your actions today can change the entire course of your life.
Choosing to remain abstinent shows that you are taking an active role in caring for your own health and acting responsibly by not jeopardizing the well-being of others.

15. HIV/AIDS—A Continuing Problem
Refusal Skills to Avoid Sexual Activity and Drugs
Avoid situations and events where drug use or the pressure to engage in sexual activity is likely to occur.
Be firm when you refuse to take part in drug use or sexual activity and use body language as well as words to get your message across.
Avoid forming a dating relationship with someone whom you know to be sexually active or a drug user.

The asymptomatic stage is a period of time during which a person infected with HIV has no symptoms.

26. Stages of HIV Infection
Symptomatic HIV Infection
The symptomatic stage is the stage in which a person infected with HIV has symptoms as a result of a severe drop in immune cells.
During the asymptomatic stage, the immune system keeps pace with HIV infection by producing billions of new cells.
Eventually the numbers of cells in the immune system decline to the point where other infections start to take over, and this marks the symptomatic stage.
The symptoms may include swollen glands, weight loss, and yeast infections.

27. Detecting HIV
EIA Test
The first test usually performed is an ELISA, or EIA.
The EIA may give inaccurate results for two reasons:
EIA is a test that screens for the presence of HIV antibodies in the blood.
Developing antibodies takes time.
Certain health conditions such as hemophilia, hepatitis, and pregnancy.

28. Western Blot Test Detecting HIV

If done properly, this test is 100 percent accurate.
If the results of all three of these tests are positive, a person is determined to have HIV.
The Western blot, or WB, is the most common confirmation test for HIV in the United States.
