For the first time in months, the Chinese province of Hubei, where the coronavirus first emerged, is getting attention for a good reason. COVID-19 cases there have dropped to practically zero, and last week authorities lifted travel restrictions in and out of the province, some 60 days after much of it was dramatically locked down. Now scientists — and the rest of the world — are watching closely to see whether easing the intense measures to keep people apart results in an emergence of new cases. An early analysis suggests that, so far, these fears have not come to pass.
