Smallpox is a contagious disease caused by the variola virus. The disease was eradicated globally as a result of vaccination, with the last naturally occurring case occurring in 1977. It does remain as a potential bioterrorism weapon. Smallpox was transmitted from person-to-person through contact with smallpox sores and through coughing or sneezing. Symptoms of smallpox include a fever and a distinct rash.
