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 is an infectious disease of the past that was eliminated by vaccination. The disease was caused by the variola virus, which spread from person to person. Affected people became very ill with a high fever and a characteristic rash. Up to one-third of people with smallpox died. Although the disease has been wiped out, samples of the virus still exist in high-security laboratories in the United States and Russia. This has led to concerns about use of the virus in biological warfare.
