Much sooner than March. Taiwan didn’t believe the ccp communist chinese(always small letters) from the very beginning & began taking measures on December 30, 2019 when Taiwan first heard of the virus AND even BEFORE the ccp coronavirus had a name. Taiwan has done miracles in their country, limiting ccp coronavirus to 450 cases & 7 deaths. Reports, even a month ago, indicate that the ccp chinese communists(always small letters) knew of the ccp coronavirus even in August 2019 (earlier?).
