ONE WORLD ESSAY: SCIENCE IMPACTS ON AIDS

        Acquired Immune Deficiency  Syndrome better known as AIDS is a syndrome, because it has a great amount of complications and symptoms more than a normal disease. This syndrome can be acquired when the human immune system is deficient. This syndrome is caused by the virus HIV (Humam Immunodeficiency Virus). This virus invades you T-4 and CD cells, that are responsible for killing the diseases. However, with HIV invading them to multiply itself and then killing the cells responsible to fight diseases and infenctions, with time there are no cells left to kill the virus and therefore HIV, becomes the syndrome AIDS that cannot be cured. AIDS is being more commom by the days that are going by since the transmission of HIV is easy to happy. HIV can be transmitted through direct contact of mucous membrane or bloodstream with someone containing the virus. The transmission can happen through many different ways, such as: unprotected sex, childbirth, blood transfusions, breast milk, injection drug needles and any type of blood direct contact.

Even though, we have a lot information about what AIDS and HIV are and what they do to humans, scientists still have not figured out why the HIV virus is so powerful that can kill almost all human immune cells. It is scary how the amount of people contracting HIV is getting bigger everyday and that almost 90% of our population is infected by this virus, and from 42 to 59% of the people infected by it those do not have any type of treatments to go against this. Therefore since AIDS is a sydrome that if contracted once it kills, scientists a while ago started doing some researchs to try to discover a solution to go against this syndrome.

Scientists have demonstrated some promising results about testing Pre-Exposure Prophylaxis (PrEP) for HIV, which are HIV drugs to prevent it before contracting it. Taking medicine or being vaccinated to don’t contract a disease or a virus is not any news, but for HIV it is. In July 2011 TDF2 Study and Partner’s PrEP Study demonstrated that “clear evidence that the antiretroviral drugs used to treat HIV can be used to prevent heterosexual transmission of HIV from men to women and from women to men” (AIDS.GOV,2011). There were also good news to the homosexuals, because as the results mentioned in ...
