One of the reasons smallpox was so dangerous and deadly is because itâs an airborne disease. Airborne diseases tend to spread fast. Coughing, sneezing, or direct contact with any bodily fluids could spread the smallpox virus. In addition, sharing contaminated clothing or bedding could lead to infection.
In China, powdered smallpox scabs were blown up the noses of the healthy. The patients would then develop a mild case of the disease and from then on were immune to it. The technique did have a 0.5â2.0% mortality rate, but that was considerably less than the 20â30% mortality rate of the disease itself.ublication of the Inquiry and the subsequent energetic promulgation by Jenner of the idea of vaccination with a virus other than variola virus constituted a watershed in the control of smallpox for which he, more than anyone else deserves the credit.
