yes. They can afford to test multiple times per week. We can’t.
They entertain millions. We don’t.
Read Kante’s article on overall risk of soccer. It’s a good study. Basically, if one person in a high level soccer game has covid, the other 21 players get exposed for an average of 90 seconds. (Not all equally. Most get less, the ones guarding him get more.). But a total of about 30 minutes of exposure, spread over 21 people.
90 seconds for a whole game that lasts 90 minutes. Thus 1 second per minute
The Aarhus University study was the one that was used to get people back on the pitch with the 90 seconds of total interaction with 1 person sick.
Other studies were done as well and the biggest interaction between players was during corner kicks. One of the reasons some states have started up soccer again with modified rules on slide tackles and corner kicks.
