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.
Smallpox was an important cause of illness and death in the developing world until recent times. In 1980, the World Health Organization (WHO) declared that smallpox had been completely wiped out. The last case was noted in Somalia in 1977. Variola represents a significant threat as a biological warfare agent. Variola is highly infectious and is associated with a high death rate and secondary spread. Currently, the majority of the U.S. population has no immunity, vaccine is in short supply, and no effective treatment exists for the disease.
