In early December, nobody had any idea this virus existed. The earliest patient checked into Wuhan Central Hospital on 16 December 2019, and doctors treated the patient with flu drugs. They only ordered lab tests in late December, and the first test results came back on 27 December 2019. That was the first moment that anyone had any evidence of a new virus.

This is an important issue, so please be careful about verifying your claims before you make them.
