History of HIV First appeared in USA in early 1980’s Originated in Africa The HIV virus in humans evolved from a virus in these primates: 1. Sooty mangabey monkey 2. Chimps The virus is called SIV: Simian Immunodeficiency Virus

What is HIV? HIV is an RNA virus HIV infects the T cells T cells help fight off infections HIV is a type of “Hidden Virus”

HIV or Human Immunodeficiency Virus The four major routes of transmission: Unprotected sex 2. Contaminated needles 3. Breast milk 4. Transmission from an infected mother to her baby at birth Blood transfusions are not longer a problem HIV or Human Immunodeficiency Virus HIV destroys a part of the immune system. It affects T-cells which are white blood cells These white blood cells fight viruses, bacteria and help prevent diseases.

The 4 major routes of transmission of HIV: 1. Unprotected sex 2. Contaminated needles 3. Breast milk 4. Transmission from an infected mother to her baby at birth * Blood transfusions are not longer a problem

AIDS or Acquired Immunodeficiency Syndrome AIDS is the diseases caused by HIV or Human Immunodeficiency Virus When too many T cells are destroyed by HIV they can no longer fight off infections The individual now has the disease called AIDS Person can have AIDS for years and not know it. Why is this dangerous????? Human T lymphocytes (T cells) Magnification 2,600x

AIDS and other diseases People with AIDS get other diseases and infections 1. Cancer – Kaposi's sarcoma 2. Hepatitis C 3. Fungal infections 4. Bacterial infection 5. Non-Hodgkin Lymphoma – blood cancer involving Lymphocytes 6. Lung Cancer 7. Cancer in the digestive tract

AIDS PREVALANCE (Who has AIDS) In 2005 Worldwide: Close to 40 million people worldwide are infected Almost 4 million people were infected in 2005 65% of AIDS victims live in sub-Saharan Africa * 70% of these victims are WOMEN Close to 15 million children are orphans due to AIDS In the U.S. 1 – 1.2 million people have AIDS 25% may not even know they are infected

Is there a cure for AIDS? Unfortunately NO!!!! But, there are drugs that can stop HIV from causing more damage to the T-cells and the immune system. These are called Antiviral drugs What can you do to prevent HIV from spreading?????

Q: Which cells of the immune system does the HIV virus destroys? Review Questions Q: Which cells of the immune system does the HIV virus destroys? A: T-Cells Q: What are the 4 major routes of transmission? A: Unprotected sex Sharing contaminated needles Breast milk From mother to her unborn baby Q: What is the name of the disease caused by HIV? A: AIDS or Acquired Immunodeficiency Syndrome Q: What kind of a virus is HIV? DNA or RNA A: RNA

Q: What happens when too many T cells are destroyed? A: The person gets AIDS and other diseases Q: Name 3 other diseases or infections that people with AIDS can get? A: Kaposi’s Sarcoma Lung cancer Infections Q: Is there cure for AIDS? A: Not at the present time but scientists are working very hard. Will you be the scientist who discovers the cure????? Q: Is there any treatment? A: Yes, antiviral drugs are now available to help patients live longer lives
