the aids epidemic in africa

  1. 1. The AIDS epidemic in Africa: what is happening? By Chris Lovata Haynes 2nd
  2. 2. Background <ul><li>The AIDS epidemic in Africa is an increasing problem leading to nearly 68% of the worlds total AIDS population is located in Africa nearly 22.2 million people. If this situation is not rapidly taken care of it will become a much bigger problem. </li></ul>
  3. 3. What is AIDS? <ul><li>HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system (the body's defense against infection). HIV uses healthy white blood cells to replicate itself, breaking down the immune system and leaving the body more susceptible to illness.  Without treatment, most people infected with HIV become less able to fight off germs that we are exposed to every day.  Someone who has HIV is called &quot;HIV positive&quot; or &quot;HIV+&quot;.  </li></ul><ul><li>AIDS (Acquired Immune Deficiency Syndrome) is a late stage of HIV infection.  An HIV positive person is diagnosed with AIDS when their immune system is so weakened that it is no longer able to fight off illness. People with immune deficiency are much more vulnerable to infections such as pneumonia and various forms of cancer. These diseases are called opportunistic infections because they take advantage of the weakened immune system. Ultimately, people do not die from AIDS itself, they die from one or more of these opportunistic infections.  It is believed that all people who become HIV+ will eventually have AIDS. </li></ul><ul><li>http://www.lifebeat.org/just_the_facts.htm </li></ul>
  4. 4. Types of Aids <ul><li>Acute AIDS is in the form of HIV. </li></ul><ul><li>Once the disease progresses it becomes AIDS. </li></ul>
  5. 5. What causes Aids? <ul><li>Sexual transmission </li></ul><ul><li>Transmission through infected blood </li></ul><ul><li>Transmission through needle sharing </li></ul><ul><li>Transmission through accidental needle sticks </li></ul><ul><li>Transmission from mother to child </li></ul>
  6. 6. Early infection <ul><li>When first infected with HIV, you may have no signs or symptoms at all, although it's more common to develop a brief flu-like illness two to four weeks after becoming infected. Signs and symptoms may include: </li></ul><ul><li>Fever </li></ul><ul><li>Headache </li></ul><ul><li>Sore throat </li></ul><ul><li>Swollen lymph glands </li></ul><ul><li>Rash </li></ul><ul><li>Even if you don't have symptoms, you're still able to transmit the virus to others. Once the virus enters your body, your own immune system also comes under attack. The virus multiplies in your lymph nodes and slowly begins to destroy your helper T cells (CD4 lymphocytes) — the white blood cells that coordinate your entire immune system. </li></ul><ul><li>http://www.mayoclinic.com/health/hiv-aids/DS00005/DSECTION=symptoms </li></ul>
  7. 7. Later infection <ul><li>You may remain symptom-free for eight or nine years or more. But as the virus continues to multiply and destroy immune cells, you may develop mild infections or chronic symptoms such as: </li></ul><ul><li>Swollen lymph nodes — often one of the first signs of HIV infection </li></ul><ul><li>Diarrhea </li></ul><ul><li>Weight loss </li></ul><ul><li>Fever </li></ul><ul><li>Cough and shortness of breath </li></ul><ul><li>Latest phase of infection During the last phase of HIV — which occurs approximately 10 or more years after the initial infection — more serious symptoms may begin to appear, and the infection may then meet the official definition of AIDS. In 1993, the Centers for Disease Control and Prevention (CDC) redefined AIDS to mean the presence of HIV infection as shown by a positive HIV-antibody test plus at least one of the following: </li></ul><ul><li>The development of an opportunistic infection — an infection that occurs when your immune system is impaired — such as Pneumocystis carinii pneumonia (PCP) </li></ul><ul><li>A CD4 lymphocyte count of 200 or less — a normal count ranges from 800 to 1,200 </li></ul><ul><li>By the time AIDS develops, your immune system has been severely damaged, making you susceptible to opportunistic infections. The signs and symptoms of some of these infections may include: </li></ul><ul><li>Soaking night sweats </li></ul>
  8. 8. Later infection cont. <ul><li>Shaking chills or fever higher than 100 F (38 C) for several weeks </li></ul><ul><li>Dry cough and shortness of breath </li></ul><ul><li>Chronic diarrhea </li></ul><ul><li>Persistent white spots or unusual lesions on your tongue or in your mouth </li></ul><ul><li>Headaches </li></ul><ul><li>Blurred and distorted vision </li></ul><ul><li>Weight loss </li></ul><ul><li>You may also begin to experience signs and symptoms of later stage HIV infection itself, such as: </li></ul><ul><li>If you're infected with HIV, you're also more likely to develop certain cancers, especially Kaposi's sarcoma, cervical cancer and lymphoma, although improved treatments have reduced the risk of these illnesses. </li></ul>
  9. 9. AIDS at home <ul><li>More than 15 million children have been orphaned by AIDS </li></ul><ul><li>Every 15 seconds another person in Africa ages 15-24 becomes infected with AIDS. </li></ul><ul><li>One child dies every minuet to AIDS </li></ul><ul><li>Not only do the children suffer from AIDS they also suffer from starvation. With no parents the kids are all alone. </li></ul><ul><li>http://projects.psi.org/site/PageServer?pagename=Statistics_nr&gclid=CJCdwfr-u5kCFQwxawod4SOD4A </li></ul>

  11. 12. Action plan # 1 <ul><li>Inform people what is happening </li></ul><ul><li>Spread the word about Africa and AIDS </li></ul><ul><li>People have to first understand the problem if they want to fix it. By allowing people to have the opportunity to learn more about it we can develop or further action plan. </li></ul>
  12. 13. Action plan #2 <ul><li>At the moment I am setting up a website based around the issues of Africa. </li></ul><ul><li>People will be able to learn here </li></ul><ul><li>And donate. </li></ul>
