Smallpox is caused by the variola virus, which is a member of the Poxviridae family. Humans do not contain any percentage of smallpox DNA in their own genetic material, as smallpox is a distinct virus that does not integrate into the human genome. However, the variola virus and its genetic material have been studied extensively in historical and scientific contexts, especially since smallpox was eradicated in 1980.

Several famous individuals are known to have contracted smallpox, including Queen Mary II of England, who suffered a severe bout that contributed to her death in 1694. Another notable figure is the American founding father George Washington, who had smallpox during a military campaign and later promoted vaccination to protect his troops. Additionally, the musician and composer Johann Sebastian Bach is believed to have contracted the disease, which affected his health in later years.
