Edit: My previous edit ran on "wrong" info. The 50+ close contacts for one of the confirmed patients is most likely from the flight.
But stay safe and be wary of who you book for FL/ML during this period. Especially those who have went back and only recently returned in the past 1-2 months when this Wuhan thing started.
