Arcangelo et al., 2017 explain that human immunodeficiency virus (HIV) is a retrovirus; eachviral particle contains two singles stranded molecules of RNA rather than deoxyribonucleic acid (DNA). Following infection of host cells, the viral enzyme reverse transcriptase allows synthesis of a DNA molecule that is then inserted into the DNA of the host cell, allowing the virus to replicate. In the case of HIV, the host cells are CD4 T lymphocytes, which is a white blood cell involved in cell-mediated immunity. When the virus replicates, it destroys the CD4 T lymphocytes, thereby leading to immune deficiency. HIV is also known as the virus that causes acquired immunodeficiency syndrome (AIDS) (Arcangelo et al., 2017). There is two classification of HIV which are HIV-1 and HIV-2 (Arcangelo et al., 2017). Arcangelo et al, 2017 discuss the difference between HIV-1 and HIV-2; which is HIV-1 “account for the majority of cases worldwide, including in the United States, whereas HIV-2 is primarily found in West Africa and is less efficiently transmitted and results in a slower disease progression than HIV-1” (Arcangelo et al., 2017). According to CDC HIV, an estimated 1.1 million people in the United States were living with HIV at the end of 2015. Of those people, about 15%, or 1 in 7, did not know they were infected.Gay, bisexual, and other men who have sex with men bear the greatest burden by risk group, representing an estimated 26,200 of these new HIV infections.Statistics also state that there were 1.5 million deathsattributed to HIV all over the world (Arcangelo et al., 2017). The most common cause of HIV is by sexual contact with a person who is infected with HIV (Arcangelo et al., 2017). 1.5million is a lot of deaths and 1.1 million people infected with HIV is a huge number. The reason for these death and people being infected is lack of knowledge of the importance of
