Not really. They could easily keep a distance from everyone else. No need for them to get close to the players.They'd all have to be tested and live under controlled conditions. And many volunteers are old and not especially healthy.
Probably best to leave it to the players and caddies who are tested regularly and more at risk of a stray asteroid...
I do accept there is now a level of paranoia about all of this, don't touch anything etc, and the players and caddies will be living in a bubble and tested regularly.
