The latest cluster of cases in Hong Kong comes from...dance clubs.  

Who'd have guessed that a lot of people not wearing masks in an enclosed space could cause the spread of COVID-19?  

Well, maybe anyone who remembered the several large clusters earlier in the year from banquets where groups of people were dancing without masks. 

That also seems to be happening again, though possibly on a smaller scale (and maybe with less dancing).  Of course they follow the law by having the guests all seated in tables of four (or six previously), but people move from table to table without putting on masks.

On the other hand, it was very noticeable on Sunday that there were fewer people out and about, so there is some hope.  Well, that and the vaccines, of course.
