The Virus that causes AIDS was discovered in 1983 by Dr. Jay Levy and his crew at the University of California. AIDS is the 3rd and worst degree of the HIV virus.
AIDS is a weakness to the immune system. It was important in a sense that it was now known to the people. It was no longer foreign
AIDS was even scarier in America because during the 1980s the gay populations in America were increasing. The fact that AIDS was a thing made a lot of homophobic people think this AIDS was meant to happen
AIDS is still in America today. 1.1 million people are currently living with AIDS and 15% don't even know they have it.
Even now 26,000 gay men a year get AIDS. Though they have medication that does not cure AIDS but instead makes you live longer.
The problem with AIDS impacted the rights of gay men and women. Before AIDS was discovered we thought that it was contagious, and even discussed quarantine.
In 2014 the spread Ebola is another (much smaller) example of the spread of an incurable disease. AIDS came from chimpanzees and was discovered in 1999 that it is nearly identical.
