So I’ve just read this article at aljazeera.com
There was still mainstream scientific support for the lab escape theory at the time of writing – published April 8. There are two biolabs in Wuhan; a Centre for Disease Control public health lab right across the road from the wet market said to be the origin, and a “highest security” BSL4 lab some miles away. Both labs work with bat viruses, and the BSL4 lab has the largest collection in the world of viruses found in bats. Scientists from China’s top polytechnics published a pre-print paper (ie. not peer reviewed) saying that SARS-CoV-2 may have leaked from the public health lab, which has also had biosecurity breaches involving contamination of staff. SARS and other coronaviruses are handled with a lower level of security not requiring full decontamination of staff, and the original SARS leaked from labs four times rather than the two I mentioned elsewhere. There is no worldwide body overseeing biolabs.
It’s just not good enough.
