Russian Anthrax leak Some call it the “biological Chernobyl.” On 2 April 1979, a plume of anthrax spores was accidentally released from a secret bioweapons facility in the Soviet city of Sverdlovsk. Propelled by a slow wind, the cloud drifted southeast, producing a 50-kilometer trail of disease and death among humans and animals alike. At least 66 people lost their lives, making it the deadliest human outbreak of inhalation anthrax ever. |
