The discovery of the vials prompted a lockdown of the facility, which has since been lifted. The FBI and CDC launched investigations, which remain ongoing.

Smallpox, a disease caused by the variola virus, is considered so deadly that only two labs in the world are authorized to store samples of the virus, including one in Russia and the other at the CDC in Atlanta.
