Up to now, Wuhan is only large city which has eradicated virus. Read this interesting tweet about their technique. https://twitter.com/XihongLin/status/1236274898760327168

In Ontario right now where stay-at-home in place, we have more or less linear growth in caseload, no reduction. I presume that our R is still above 1. More or less same as Wuhan prior to centralized quarantine. Not encouraging.

I recommend @XihongLin for insightful commentary on coronavirus.
