Countries hosting dangerous pathogen labs lack biosecurity

Three-quarters of countries that host labs designed for the study of the most dangerous pathogens fail to meet the highest standards for biosafety and biosecurity. 

Theories about a laboratory origin for SARS-CoV-2, the virus that causes COVID-19, have spotlighted biosafety level 4 (BSL-4) laboratories. The Wuhan Institute of Virology, located near the market where the first detected coronavirus superspreader event occurred, is one such laboratory. The likelihood that the coronavirus could have escaped from the lab is hotly debated, with some researchers saying that the possibility should be investigated more thoroughly.
