There is no cure for AIDS or HIV. There are however, symptomatic treatments do exist. These treatments can prolong the life of a patient. Symptoms include: fever, chills, night sweats, skin rashes, headaches, malaise, swollen lymph nodes, and general discomfort. Flu-like symptoms occur several months after infection. This epidemic is a current one, which began in the mid- 70s,and has effect virtually everyone from the lower class to upper class white senators.

Although the number still grows, as of today, 18.8 million people have died from this epidemic.
