It isn't that they needed to act in November. The virus was only taken seriously by the Chinese in December. However by mid-December no action has been taken by the US government. Only marginal action was seen in January, when it was a sure-fire knowledge that people would have gone to the US not knowing they had it. Even now, there is inadequate provisions and action by the US. It was only in March when the US gov started rolling out testing and screening, finally fully committing to it. If they had started doing what they're doing now, in January, it's likely the US would have been on the tail-end of the pandemic by now.
