Anti Retroviral Drugs For Hiv Essay - 1337 Words

HIV is a virus that affects all parts of the globe. However, there are two major global epidemics. The first being in the west and developing countries. In these areas the pattern of infection is found in certain groups. These groups being â€Å"drug injectors, gay men and prostitutes† (Pisani p. ) This epidemic is known as the â€Å"concentrated epidemic†. This particular pattern HIV spreads rapidly in a concentrated groups. This is because you are most likely to pass on the virus when you are in the first stage of HIV. In a concentrated tight knit group of people who are having several sex partners and sharing needles with others it is easy for the virus to be transmitted. The other epidemic pattern is seen in east and southern Africa as well as some parts of east Africa and the Caribbean. This pattern is also known as â€Å"generalised epidemic†. This pattern is different because HIV is in the general population appose to a concentrated population. 2. There are three different classes of anti-retroviral drugs for HIV: a) The first class of drugs are called the entry inhibitors. The entry inhibitors inhibit the HIV virus to bind to the T helper cells, also called the CD4 T cells. In order for these cells to become infected the virus, the virus has to bind and enter them. If the binding is eliminated therefore the virus can not enter the cell. b) The second is called, integrase inhibitors. Once the virus has entered the host cell, it replicates it’s DNA into the cell.

It is important to understand drug resistance when working with clients who have HIV/AIDS because drug resistance can occur at any time during treatment.

Nearly every HIV infected person will ultimately develop and die from AIDS, if the
