You have a point here. See the article below on imported cases may trigger a second outbreak.I don't like this. In fact I don't like this at all. China has become too lacks too soon and its just a matter of time before we will see a second wave. Its no different what I have seen in Europe a month ago. When people thought this was just a problem abroad and nothing to worry about at home.
And then there is this. The biggest threat to China now is from imported cases. And yet the quarantine of foreigners travelling to China is haphazard and uncoordinated.
