Does HIV Discriminate?

Does HIV discriminate? With HIV being on the rise in so many young people, one has to ask themselves why? Are people being educated on the spread of HIV and how the disease affects them? In the writing I will discuss what HIV is, how it is transmitted, how it attaches to a host, diagnostic testing, and the stages of HIV. I will also discuss varies treatment for HIV, as well as explain the epidemic of HIV in the USA and prevention of the spread of HIV. HIV (human immunodeficiency virus) is a virus that attacks the white blood cell (WBC) breaking down the body immune system. It attacks and destroys the cd4 cells of the WBC. Leading too weaken immune system and the body inability to fight of infection. There are two stages of HIV. The first

Once, the infection comes in contact with a suitable host cell such as a person who is CCR 5 positive the virus approaches its targeted cell and its GP 120 receptors binds to CD 4 receptors of the cell. Then bind to co-receptor CCR 5 which changes Gp120 to Gp 41. Gp41 then insert its terminus into the cell. The terminus of GP 41 then begins to fold on its self, drawing the virus into the cell and facilitate the fusion of the membranes. The virus enters the host cells and breaks open releasing two RNA virus release strain and three replication enzymes (reverse transcriptase, integrase and protease). The reverses transcriptase then begins to transcribe a single-stranded RNAs into an RNA/DNA double helix at the Preliminary active site. The RNA is then broken off at the ribonuclease H active site and the DNA strain reenters the preliminary site to form a DNA double helix. The DNA them travel DNA integrase where it cuts off a section of the DNA leaving two sticky end and carries the DNA to the cell nucleus and attaches it to hosts Chromosomal DNA where it can lay doormat before being activated. Once, activated a viral messenger RNA is made and RNA travels to the cytoplasm, where new strains of virus are copied and build. The longer protein strain of the virus is process by the Enzyme protease where it cuts the virus in half to stronger core protein. These new core protein forms a capsule around two viral RNA and the three

Because HIV is able to changes it drugs should be taken in combination of three or more. NNRTI prevents HIV RNA from becoming incorporated into HIV DNA by using a faulty version of the building blocks (nucleotides) so the virus DNA cannot be built correctly by the reverse transcript. Integrase inhibitors work by blocking the processes of HIV DNA from begin integrated into the CD 4 cell DNA. Protease inhibitors works by preventing the split of HIV polyproteins into a functioning protein needed for HIV maturation, inhibiting replication of
