HIV and AIDS
HIV (Human Immunodeficiency Virus) is a complex retrovirus that causes AIDS (Acquired ImmunoDeficiency Syndrome). This retrovirus causes AIDS by infecting the T cells of the immune system and deteriorating it. This attack on the immune system leaves the person susceptible to life-threatening infections called opportunistic infections. There are currently two types of HIV: HIV-1 which is the strand of HIV that is chiefly responsible for causing AIDS worldwide and HIV-2 is a strand that is found mostly in West Africa. “The Joint United Nations Programme on HIV/AIDS believes that there are now over 34 million people that are infected with HIV or AIDS worldwide. In the United States there are nearly one million people have HIV or AIDS which is roughly one out of every 250 people. 40,000 Americans become newly infected with HIV each passing year. Since the beginning of the epidemic, AIDS has killed nearly 19 million people worldwide, together with some 425,000 Americans.”Although there is a range of theories about the origin of HIV, there is one that is believed to be true. This theory is that HIV originated from a primate SIV (Simian Immunodeficiency Virus) that then crossed over into the human population in a pr
Primarily four bodily fluids transmit HIV. These fluids are blood, vaginal fluids, semen, and breast milk. Also sharing needles that have not been sterilized after use is another way one person's blood can come in contact with another's. Although donated blood from organization such as the American Red Cross is tested for HIV, there is a slight chance that HIV can be transmitted through blood transfusions. HIV can also be transmitted through sex. This includes oral, anal, and vaginal sex. Mothers who are infected with HIV can also transmit HIV by breastfeeding their child. A child born from a woman with HIV has a 30% chance of getting HIV, primarily through the birthing process (researchers have found that caesarean sections at birth, and the use of some drugs can lower the chances of a child being infected with HIV through birth). Although some think this, HIV cannot be transmitted through hugging, kissing, holding hands or sharing food or a drink with someone who is infected. And although HIV can sometimes live in saliva, but it would take two gallons at once, for anyone to be infected with HIV this way. ocess known as zoonosis (zoonosis is the process in which viruses pass from animals to humans). It is believed it may have crossed over from a chimpanzee population. But this SIV is very uncommon among the chimpanzee population, thusly it is now thought that chimpanzees may have contracted it from perhaps another primate species. Although the source of the HIV-1 virus is still unknown the HIV-2 virus, has clearly been identi
