1. Infection with either variola major or variola minor confers immunity against the other.

2. Did you find the part about the variola incubation periods stimulating enough?

3. In a horrible explosion in the early morning on the following day, a 16-year-old accordionist Ivica Brusić, a mežnjar (eng. sacristan) Josip Variola and Anton Variola were killed.

4. Biodefense What is smallpox? Smallpox is an infectious disease caused by the Variola virus

5. The Cowpox virus is closely related to variola, the causative virus of smallpox

6. Synonyms for Amaas include alastrim, Cuban itch, kaffir pox, milk pox, pseudovariola, variola minor, West Indian pox and white pox

7. Smallpox as a Bioweapon Although naturally occurring smallpox has been eradicated, there is still heightened concern that the variola virus might be used as an agent of bioterrorism

8. However, as the risk of death from inoculation with Variola Minor was just 1% to 2%, as compared to the 20% risk of death from the natural form of smallpox, the risks of inoculation were generally considered acceptable.

9. CDC Bioterrorism Agents Category A ¾ Anthrax (Bacillus anthracis) ¾ Botulism (Clostridium botulinum toxin) ¾ Plague (Yersinia pestis) ¾ Smallpox (variola major) ¾ Tularemia (Francisella tularensis) ¾ Viral hemorrhagic fevers (filoviruses [e.g., Ebola, Marburg] and arenaviruses [e.g., Lassa, Machupo]) Category B ¾ Brucellosis (Brucella species) ¾ Epsilon toxin of Clostridium perfringens
