@Regrann from @drlindseyfitzharris - Photo of a smallpox victim from 1868. Smallpox is one of the deadliest and most contagious diseases known to mankind. Just one teaspoon of the virus is enough to infect every man, woman, and child on the face of the earth. .
The virus killed over half a billion people in the twentieth century alone—three times the number of deaths from all of the century’s wars combined. The human species is the only natural host of smallpox. No other organism can harbor the virus. Once inside the body, it begins replicating itself millions of times over. The incubation period is around ten days, during which time an infected person shows no signs of being ill. Afterwards, the victim develops a high fever and aches, followed by a rash on the face, hands, and feet. .
Smallpox blisters are hard to the touch, and filled with a clear, faintly opalescent pus. Some cases develop into hemorrhagic smallpox, which causes the skin to slough off in sheets as the patient bleeds from the nose, mouth, and eyes. .
On May 8, 1980, the World Health Organization (WHO) announced the eradication of smallpox. It was an unprecedented event in history. The vaccination was discovered by Edward Jenner, who first tested it on a human on May 14, 1796.
