I do not claim to know where the COVID-19 virus originated. And, I don't think we will ever know for sure. But claims and counterclaims about its origin highlight a systemic problem that goes far beyond the details of this debate. In this case, those positing a possible laboratory origin believe that scientists manipulating coronaviruses for research purposes may have carelessly let one of their altered viruses infect them. The scientists then unknowingly carried the virus out of the lab and into the streets of China.
What's important about this scenario—and again, we have no definitive evidence it happened—is that it could occur in any of the special laboratories worldwide which study dangerous infectious diseases. A recent report highlighting the problem listed 59 biosafety level 4 labs (the highest level), a tally that includes those planned and under construction. Some 42 are believed to be currently operating. These labs "are designed and built to work safely and securely with the most dangerous bacteria and viruses that can cause serious diseases and for which no treatment or vaccines exist." (For a very brief primer on biosafety levels, read this.)
So, how closely are these labs monitored? The report continues, "There is, however, currently no requirement to report these facilities internationally, and no international entity is mandated to collect such information and provide oversight at a global level. Moreover, there are no binding international standards for safe, secure, and responsible work on pathogens in maximum containment labs."
