Non-propagative diagnostic laboratory work including, sequencing, nucleic acid amplification test (NAAT) on clinical specimens from patients who are suspected or confirmed to be infected with nCoV, should be conducted adopting practices …. … in the interim, Biosafety Level 2 (BSL-2) in the WHO Laboratory Biosafety Manual, 3rd edition remains appropriate until the 4th edition replaces it.
Handling of material with high concentrations of live virus (such as when performing virus propagation, virus isolation or neutralization assays) or large volumes of infectious materials should be performed only by properly trained and competent personnel in laboratories capable of meeting additional essential containment requirements and practices, i.e. BSL-3.
Did anyone do some research?

(SARSr-CoV) makes the BSL-4 list on Wikipedia.
But what’s the probability that animal-based coronaviruses (being very widespread in a lot of species) were restricted to BSL-4 labs?
