Smallpox was declared eradicated in 1980, world health authorities said the only known samples left were safely stored in super-secure laboratories in Atlanta and in Russia.Many scientists argue that any remaining samples pose a threat and that the deadly virus should be wiped off the planet altogether. A few days ago, earlier in July, an unexpected and frightening discovery alerted scientists and security services in the United States . Decades-old vials of smallpox packed away and forgotten in a cardboard box were found in a building at the National Institutes of Health in Bethesda, Maryland, that has been used by the Food and Drug Administration since 1972. Labeling indicated that the smallpox had been put in the vials in the 1950 and it’s not known if the virus is live and infectious. Fortunately, no one has been infected, and no smallpox contamination was found in the building. The samples were rushed under FBI protection to the CDC in Atlanta for testing.
