Smallpox is the infectious disease produced by Variola major. It was the first infection for which a preventive measure, vaccination, was introduced; it is the first infectious disease that has been eradicated from the wild. A new case of smallpox would almost certainly be a use of a biological weapon, probably as terrorism, and constitute a major worldwide emergency.
By world agreement, only two stocks of the smallpox pathogen exist: in high-security government laboratories in Russia and the United States. There are concerns, however, that there may be cultures elsewhere, and, since it is transmissible from human to human and has substantial morbidity and mortality, there are worldwide preparations for containing and treating an outbreak. The vaccine, while having significant side effects, can reduce the severity of an active case as well as prevent the disease. At least one antiviral drug, cidofovir, is believed active against it, but has not been used in humans.
