Medical Diseases Smallpox Laboratory Assistants Work Full Out At Liverpool Sealing Up Smallpox Vaccine Smallpox Was An Infectious Disease Unique To Humans Caused By Either Of Two Virus Variants Variola Major And Variola Minor. The Disease Is Also Known By The Latin Names Variola Or Variola Vera Which Is A Derivative Of The Latin Varius Meaning 'spotted' Or Varus Meaning 'pimple'. The Term 'smallpox' Was First Used In Europe In The 15th Century To Distinguish Variola From The 'great Pox' (syphilis).
