I mean, there is closing the door after the horse has bolted and then there is the kind of reaction that Italy has….One could understand China, but the rest of the countries (including the US) have had lots of time to prepare….and they didn’t. Lots of time to stop the entry of this virus into the borders…..and chose to do nothing.
Until now, when there are travel restrictions in at least one country in Europe and lots of places here in the US are cancelling events where large gatherings of people might have occurred. Schools are closing or cancelling classes. Where have our health officials been for the past 45+ days?
Trust your government.
