Spending one hour in a small restaurant room without windows sitting next to a family who just escaped from Wuhan on January 24th is the reason for the contagion, not any AC issue. Bad title. Astute but useless study by the CDC.

I agree with your comment, but how does "astute and useless" go together?

Astute + useless = pedantic.

Most of the people that spent time in the room didn't get infected.
