What was the main problem for small pox

One of the reasons smallpox was so dangerous and deadly is because it's 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.

Smallpox is an ancient disease caused by the variola virus. Early symptoms include high fever .
