LetterBiosafety threats of the rapidly established labs for SARS-CoV-2 tests in China.
To increase the capacity of identifying coronavirus disease 2019 (COVID-19) infection, many Biosafety Level 2 (BSL-2) labs have been established in a short period of time for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid tests all over the world. However, their biosafety has not been evaluated, which could have been the first gateway to SARS-CoV-2 transmission. During 9-11 March 2020, the first comprehensive evaluation of the biosafety in all 89 labs qualified for conducting SARS-CoV-2 tests in Sichuan Province of China was conducted. ⋯ Other severe risk included failure for standard labeling of SARS-CoV-2 wastes and lacking regular monitoring of sterilization effects. Our findings would provide experiences and lessons for strengthening lab biosafety in other Chinese provinces, and also serve as an important reference for many other countries where such labs are being or will be quickly built for fighting the COVID-19. The information of lab safety should be considered to be internally linked to the national intelligent syndromic surveillance system (NISSS), for better improving the safety of the labs at the greatest need and facilitating more comprehensive surveillance of risk for disease outbreak.
