what is the most severe disease?

Kaylee Schmittou: The worst disease of all time was either the flu or the bubonic plague. Both killed a huge amount of people in the old days, before we found a cure for both. Small pox also had a huge epidemic. But the flu killed the most Americans, though the bubonic plague came before America even existed. Currentley, in modern days, I believe that AIDS is the worst disease though. It is attained by one of the natural things of life, when you're trying to reproduce. When you get it, it kills your immune system, and you can even die from a common cold. If you somehow survive, you end up dieing slowly, which is even worse. AIDS slowly kills you to where you can't walk and you're stuck in bed. The only thing that protects you is a condom. You have to be careful not to get it because it can ruin your whole life.
