HIV/AIDS ~Facts vs. Myths Presented By: Ms. Mack Chemistry I and Physical Science Honors December 15, 2008

What is HIV?  The acronym “HIV” stands for Human Immunodeficiency Virus.  HIV is a retrovirus-

The Mechanism of HIV  There are several stands of the virus.  HIV enters the body and attacks the hosts’ immune system, (white blood cells).  The body’s immune system is based upon B cells (memory) and T cells (target).  HIV enters the T-cells (specifically CD4), replicates and in turn, weaken the body’s immunity.

How does one become exposed?  Sexual intercourse  Sharing needles  Mother to Child  Blood transfusions  Transplants/surgeries

How is HIV contracted?  Transmission of Bodily Fluids Blood Semen Vaginal Secretions  HIV has yet to be contracted exclusively from kissing, coughing, touching, or holding hands.

Why is HIV so harmful?  The immune system is the most important line of defense for the human body.  HIV compromises one’s immune system, causing it grow helpless against other illnesses.  If undetected and untreated, HIV can develop to AIDS.

Continued…  A person may live with HIV for 10 years or longer with no symptoms (asymptomatic).  Some symptoms include: flu-like systems: fever, chills, rash, soar throat  If properly treated, a small group of people never develop AIDS at all.  Early detection is key.

What is AIDS?  “AIDS” stands for Acquired Immune Deficiency Syndrome- the disease that results from HIV.  When the body’s T-cell count is detected to be lower than 200, a person is diagnosed with AIDS.  The diagnosis of AIDS represents a weakened immune system, but does not kill of itself.

Opportunistic Diseases…  Those with AIDS are in danger of fatalities from other diseases and infections, termed “opportunistic” diseases.  These may include pneumonia, bacterial and parasitic infections, viruses and fungal infections.

Detection  HIV can be detected! However, it is possible that the virus is dormant for a window of 3-6 months after contraction.  Early detection is key: Confidential HIV tests Anonymous testing Blood Test Oral Swap

Prognosis  People with HIV, or AIDS can lead normal lives.  There are TREATMENTS for HIV and/or AIDS. However, a cure has yet to be found.  One commonly used treatment is HAART (highly active antiretroviral therapy).

Statistics  Since the beginning of this great epidemic, more than half a million people have died in the United States.  There are currently more than one million people living with HIV and AIDS in the United States, 1/5 of those are unaware.

U.S. Population Breakdown

Percentage of AIDS Diagnoses in 2006  White, non-Hispanics (30%)  African Americans (46%)  Hispanics (19%)  Asian/Pacific Islander (1%)  Native American (0%)

Why is this important?  December is HIV/AIDS awareness month!  Share what you know with your peers, family and friends and be encouraged to have healthy practices towards disease prevention  Scientists seek to find the cure to this and many other diseases that plaque the world today.  Awareness leads to understanding. Understanding leads to prevention. Prevention saves lives.
