New research suggests that the ban on travel from China was ineffective while it’s only the ban on travel from Europe that, as I’ve argued before, came too late.
It also suggests that while China clearly less than forthcoming about the initial outbreak of the virus, and effectively assisted in coverup up by the World Health Organization up through January 15 (when the WHO declared there was still no evidence of person-to-person transmission of the virus), there was still plenty of time to act to contain it. Indeed, the people who brought the virus here which actually spread it into an outbreak didn’t arrive until around two weeks after the first travel ban was put into place by the U.S. government.
