Sprite - no, I haven't seen any film from anyone on batflu, but yes for the unknowns. Including we don't know exactly how the thing is spread. It would be hard to say for certain (impossible) that anyone who had this thing in December (or earlier) hadn't opened a parcel containing something from Wuhan.
Only one 'known' is relevant.
We know we don't have a vaccine. No vaccine = at best a very limited travel/tourism/hospitality industry.
