“Have there been any accidental releases from labs in the past?”
“Some experts cite the unexpected emergence of a new H1N1 strain of flu in 1977, which spread globally over three decades, as an early example of a flu virus being accidentally released from a lab. Genetic evidence points to it having escaped from a lab in China or the Soviet Union.”
“There are many examples of other infectious agents escaping from labs. Smallpox virus escaped from Birmingham Medical School in 1978 and killed a medical photographer, Janet Parker, the last person to die of smallpox. Foot and mouth virus escaped in 2007 from a veterinary lab in Surrey and in 2004 the SARS virus escaped from a high-containment lab in Beijing, infecting nine people before it was stopped.”
Ever hear of killer bees?
