Dr. Xiangguo Qiu, her husband Keding Cheng and an unknown number of her students from China were removed from Canada's only level-4 lab on July 5, CBC News has learned.
A Level 4 virology facility is a lab equipped to work with the most serious and deadly human and animal diseases. That makes the Arlington Street lab one of only a handful in North America capable of handling pathogens requiring the highest level of containment, such as Ebola.
Security access for the couple and the Chinese students was revoked, according to sources who work at the lab and do not want to be identified because they fear consequences for speaking out.
