Reminder that SARS-CoV-2 has infected people who entered a space AFTER the index patient left.

So is it msgic like measles yet?
Here. A0 and B1 shared an elevator, but NOT at the same time.

Hunan bus from April. Purple got on bus AFTER index left. China CCTVs every bus so they could track this.

In North America we just say "touched seat back" because we're stupid.

This study said not sure how got to the other floors, but either fomite (sure) or the elevator.

People reinfected with cold coronaviruses. Posted May.

Why should we assume SARS-CoV-2 would be different?

Answer cannot be "novel virus", "no solid evidence that it reinfects", "I am an expert" or "magic pony for Christmas", although the latter would be most accurate.
A general finding is that antibody is present in a significant portion of adults who, in spite of possessing this antibody, can go on to have reinfection and illness.

This is a very important paper.

Transmission over more than 2m with only 5 min exposure - captured by CCTV.

Contact tracers don't even look for these connections.

Right now when people tell you there is no airborne spread remember THEY ARE NOT LOOKING FOR AIRBORNE SPREAD BECAUSE THEY DO NOT BELIEVE IN IT.

This is why elevator buttons get blamed instead of aerial transmission - they don't believe in aerial transmission.
Let me complete the thought.

IF YOU DO NOT LOOK FOR IT YOU WILL NEVER FIND IT.
