Smallpox is a deadly disease

Smallpox, also known as Variola, is a deadly disease, which has claimed many peoples' lives throughout history.
Smallpox can basically be described as a disease which is transmitted from person to person quite easily, causing
many small to medium sized bumps on an infected person's body. Pictures of smallpox may be disturbing to some
viewers, which is why I have limited the number of pictures of infected people.
