One of the worst diseases ever is “The Black Death”. Dying with this is rather hideous as pieces of your body will form into large lumps and bubble, you will vomit blood and your skin will peel off in bits. The element of surprise was always associated with this disease, no one ever knew when and if they were likely to be infected. This disease killed one in three people in Europe and a quicker form can kill after several hours of exposure. This disease could arise again as we become more and more resistant to antibiotics. 200 million people died as a result of this disease.
