If I received a letter from an old friend explaining they have found to be HIV positive, I would offer support through being as present as I can during this trying time. There are numerous ways to offer support to a loved one who has been recently diagnosed with HIV to include: talking about the diagnosis, listening, educating yourself about the disease, how it’s transmitted, and treatment options, and encouraging treatment. Every person is different, and will handle the diagnosis differently, so being as supportive as possible and ensuring your friend knows you view them no differently is essential. How was HIV finally identified? The origin of HIV has been subject to scientific research since the identification of the virus in the 1980s. HIV is a type of lentivirus, meaning it attacks the immune system, similar to the way the Simian Immunodeficiency Virus (SIV) attacks the immune systems primates. Both viruses have many similarities as HIV-1 is related to a strain of SIV found in chimpanzees while HIV-2 is related to a strain of SIV found in mangabeys. This leads to the time old question – did HIV come from monkeys? In 1999, research was performed on a chimpanzee who was infected with a strain of SIV that was nearly identical to HIV in humans. The research uncovered that chimpanzees were indeed the source of HIV-1, and that the virus had crossed between primate to humans (Origin of HIV & AIDS, 2019). The most widely accepted theory is that SIV was passed to humans as a result of chimpanzees being hunted, as the blood could get into open cuts or exposed wounds of people, and also as a result of primates being killed and eaten, causing the virus to adapt within its new host to become HIV-1. There are four main groups of HIV strains, each being slightly different, which supports the theory that chimps were hunted and killed. Each time SIV passed from chimp to human, a different strain would have developed, explaining why there’s more than one strain of HIV-1. HIV-2 is much rarer and less infectious than HIV-1 but is believed to have been contracted in humans from mangabeys through the same means as HIV-1.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
