I don't recall that. I do remember an article recently about recreating Spanish Flu in the laboratory. It's very controversial because it spread quickly and killed millions of people in a really short time span. For smallpox, some believe it's possible it may still exist somewhere cold frozen in ice. I don't know how credible that threat is though.
