As the number of epidemics rises, we decided to take a look at the biggest epidemics throughout the history.

One of them that runs for the last 35 years is HIV. While scientists are looking every day to find a cure, the number of contagious rises. The first case of this virus appeared in 1920 in Kinshasa from where it started spreading over whole Africa and then to other continents as well. The real epidemic started 60 years ago, on June 5th, 1980 and until today, there were between 29,6 and 40,8 victims of this illness who died. Science still didn’t get the solution to resolve this problem, but at least, they found some ways to help people contained with HIV to live longer with this disease in their system. The real cause of the first recorded case of the HIV was never revealed.
