It uses envelope proteins that integrate into the host cell wall. The capsid containing the RNA then enters the cell. ]]> 2017-02-21 19:29:46 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155276413 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155278761 Viruses that utilize reverse transcriptase, like HIV, are called retroviruses. ]]> 2017-02-21 19:35:56 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155278761 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155280226 A provirus is the genetic material of a virus that is inserted and then replicated with the host's DNA. In this way, HIV is also a provirus because after the reverse transcriptase does the job, the viral DNA is integrated into the cell's DNA and more HIV viruses are made. ]]> 2017-02-21 19:39:52 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155280226 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155281731 HIV hijacks the body's immune system, targeting and destroying the CD4 helper lymphocyte cells (T cells), an integral part of the immune system. Eventually, the affected person cannot fight off diseases and will eventually die. ]]> 2017-02-21 19:43:49 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155281731 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155284105 Blood, breast milk, semen, and vaginal fluid are all ways that the HIV virus can be transmitted. ]]> 2017-02-21 19:50:16 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155284105 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155284632 HIV is a virus, while AIDS is the condition caused by HIV. A person has aids when their CD4 cells are less than 200 per cubic millimeter of blood. ]]> 2017-02-21 19:51:38 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155284632 claire_barley https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155286430 Many people are asymptomatic and only realize that they are infected once they have been tested, allowing for them to unknowingly spread the virus. Some common symptoms are genital and oral sores, flu-like symptoms, fatigue, cough, and diarrhea.

It can also lie dormant in your body as you infect other people unknowingly. Since it is most commonly transmitted sexually, there is a stigma that often defers people from seeking treatment. ]]> 2017-02-22 02:24:49 UTC https://padlet.com/claire_barley/bnpy6eubgtd0/wish/155346411
