Just FYI, most families I know are allowing their children to actively participate in the activities mentioned, albeit on a selective level, and have been doing so for a number of months. If done with common sense the risk is very low. In our circle of families there have been zero infections.
There was a parent organized scrimmage this past weekend that was incredibly well attended by kids from at least five clubs. A great time was had by all and reasonable precautions were followed (or so I was told

) .
