Again I have no experience or knowledge of this but is it really possible that this lasts up to then? I mean that's 4 to 6 months.
Surely having 4 to 6 months of major restrictions to travel and the general public is just as damaging as the disease itself.
Looking at the timeline for SARS, the index case was traced back to November 2002, and it wasn't until February 2003 when the WHO were alerted. After that it was another 5 months until the epidemic was classed as over.
The Corona outbreak started in December and China have responded better this time around (although still not great), so that may help matters, but assuming a similar timeline to SARS then that leads us up to August.
