HISTORY

HIV was originally discovered by a team of scientists,not just one person.While a team may have discovered the virus Dr. Luc Montagnier is credited the most for the discovery's he made in 1983 at the Pasteur Institute in Paris .His discovery's led directly to the development of a test for detecting the presence of HIV in blood samples.Lately the biggest outbreak of HIV has been reported in Kazakhstan,But HIV hasn't been known to cover one area.The virus is global and has been affecting countrys and nations for years.Below are the amount of people internatinally each year that live with HIV.

INTERNATION STATS OF PEOPLE LIVING W/ HIV.
  • 33 million people living with HIV worldwide
  • 30.8 million adults
  • 15.5 million women
  • 2.0 million children under 15

SYMPTOMS

HIV is a disease that shows many symptoms in many parts.Those that show early HIV symptoms will develop flu-like symptoms. This can include: fever, rash, muscles aches and swollen lymph nodes and glands.Later symptonms may vary depending on if you know you have HIV or not.If not treated Hiv will break down your immune system.Symptoms that you could have later are:
  • chronic yeast infections or thrush (yeast infection of the mouth)
  • Fever and/or night sweats
  • Easy bruising
  • Bouts of extreme exhaustion
  • Unexplained body rashes
  • Appearance of purplish lesions on the skin or inside mouth
  • Sudden unexplained weight loss
  • Chronic diarrhea lasting for a month or more.


Virus Transmitted

HIV cab be spread various ways:
  • Blood (including menstrual blood)
  • Semen
  • Vaginal secretions
  • Breast milk
Although the most common way to transmit HIV is through sexual intercourse.Animals and other organism have there own adaptations of the virus but HIV is human immunodeficiency virus so it is only logical that it would only affect humans.

Structure/Compistion


Picture_8.png
HIV particles surround themselves with a coat of fatty material membrane.Coming out of the membrane are 72 little spikes, which are formed from the proteins gp120 and gp41. Just below the membrane is a layer called the matrix, which is made from the protein p17.

Details

HIV attacks specific lymphocytes called T helper cells or T-cells,They take them over, and multiply. This destroys more T-cells, which damages the body's ability to fight off invading germs and disease.Leaving your body completely unprotected from infections.Eventually if not treated properly there is a high probaility of contrating AIDS from HIV.

---------LifeCycle

The HIV virus breaks down the immune system. The virus attacks your CD4 cells (or T4 cells), which are needed to fight off illnesses or infections. Sooner or later, the virus takes over the CD4 cells and your body starts to be unable to fight the diseases and infections off.
