Facts Tell: Why didn't the first COVID-19 autopsy happen until February 16?

The first two autopsies of patients deceased from the novel coronavirus pneumonia (COVID-19) took place on February 16 at Wuhan Jinyintan Hospital.

Understanding COVID-19 by dissecting the cadavers could help significantly with clinical treatment.

Liu Liang, forensic specialist from the Tongji Medical College at Huazhong University of Science and Technology, and his team submitted an urgent report to relevant departments as early as January 22, calling for the dissection of COVID-19 cadavers.

But why weren't these conducted earlier?
