•By 1984, HIV was discovered to cause AIDS and 3064 were diagnosed with the condition out of which 1292 died.

• Since then, the epidemic of HIV Epidemic Analysis New HIV Diagnoses in the US and Dependent Areas by Age, 2017 Epidemic analysis Prevalence of HIV/AIDS in the U.S.

• 1.1 million individuals in the U.S. contracted the disease and are living with the infection and one in seven (17%) are unaware of their status (CDC, 2018)

•There were 38,500 new infections in 2018 and 6,000 AIDS related deaths.

• Since the onset of the epidemic, 692,790 people have died from related illnesses (Singh et al., 2018).

•African Americans are affected more than other ethnic sets and groups that accounts for 44 percent for all new infections in 2014 (CDC, 2018).
