Caixin has learned that the Wuhan hospital sent [genomics laboratory] BGI at least 30 samples from different pneumonia cases for sequencing in December, and three were found to contain the new coronavirus. In addition to the Dec. 26 case, the second and third positive samples were received on Dec. 29 and Dec. 30. They were tested together and the results were reported to the Wuhan Municipal Health Commission as early as Jan. 1.
On Jan. 1, gene sequencing companies received an order from Hubei’s health commission to stop testing and destroy all samples, according to an employee at one. “If you test it in the future, be sure to report it to us,” the person said they were told by phone.
Two days later on Jan. 3, the National Health Commission issued its gag order and said the Wuhan pneumonia samples needed to be treated as highly pathogenic microorganisms — and that any samples needed to be moved to approved testing facilities or destroyed.
One virologist told Caixin that even the Wuhan Institute of Virology (WIV) under the Chinese Academy of Sciences was not qualified for the tests and told to destroy samples in its lab.

On Jan. 9, an expert team led by the CDC made a preliminary conclusion that the disease was caused by a new strain of coronavirus, according to Chinese state broadcaster CCTV.
On Jan. 11, Zhang’s team became the first to publish the genome sequence of the new virus on public databases
Virological.org and GenBank, unveiling its structure to the world for the first time. The NHC shared the virus genomic information with the World Health Organization the next day.
