Smallpox was a serious infectious disease caused by the variola virus, a poxvirus related to mpox. Smallpox outbreaks have occurred for thousands of years, but in 1980 the disease was declared eradicated following worldwide vaccination programs. Although smallpox is no longer causing global illness, high-security laboratories maintain stockpiles of variola viruses, which if lost or stolen and released as a bioweapon, could lead to a public health catastrophe.
