Canadian lab that handles world's deadliest viruses tightens security after investigation finds researchers with connections to the Chinese government and military gained access and MAILED live Ebola virus to Wuhan | 5 March 2024 | A Chinese couple working at Canada's highest biosecurity lab were secretly sending information to Beijing and mailed live Ebola to China, a bombshell investigation has found. In a 600-page report released this week by the Canadian intelligence service, the pair were also accused of allowing visitors into the lab who tried to leave carrying plastic bags of vials containing an unknown substance. Dr Xiangguo Qiu and Dr Keding Cheng were found to have left visitors with ties to the Chinese government and military unsupervised at the facility. The report also accused the pair of being in communication with the Wuhan Institute of Virology, the facility at the center of the Covid lab-leak theory, without informing superiors. The Canadian National Microbiology Lab in Winnipeg, Manitoba, where they worked as researchers, is the only BSL4 lab in the country -- and the only one to hold Ebola, as well as other deadly viruses like Marburg and Lassa fever.
