Noah Lyles has Covid
 

They announced today that even though Noah Lyles was diagnosed with Covid a couple of days ago, the USA kept it secret and he ran in the 200 meters final.

A couple of years ago, Novak Djokovic was banned from the USA and Australia. It wasn’t because he had Covid but it was because he hadn’t been vaccinated.

Should an athlete who has Covid be allowed to participate in any event? Olympics, baseball, basketball, etc.?

First thing that popped into my mind--if a guy can run at an Olympic level while "suffering" (apparently not quite the appropriate word) from a case of COVID, then how dangerous can COVID be?

Probably shouldn't be around people if contagious.

He knew 3 days earlier. So he knew he was highly contagious. Yet he still decided that running was more important. Of course, he took minimal precautions to reduce the risk to others, right?

He deliberately kept his distance, adding space so that he stayed away from others - NOPE
He never closely talked directly in front of another person - NOPE
Things he contaminated were disposed of properly so they did not expose others - NOPE
He disclosed the illness to all other people and (especially) athletes he might come in contact with - NOPE
He did not hug or touch other athletes - NOPE
He warned the medical staff so they could wear PPE - NOPE
He warned the medical staff so they could avoid touching additional people after he was handled - NOPE

That behavior gives me no hesitation from banning him for life, escort him out of the current olympic facilities, and a permanent ban from ever attending all future olympics.
