Options then include:I'm genuinely curious - how are they planning to enforce this?
- I imagine they probably already have a database with competitors listed. They can easily have field that indicates "negative covid test".
- The person who calls competitors to to the dance floor could have an indication of who is allowed to unmask next to each name. They could look to see if they are masked or unmasked and pull violators off the floor. (They could also then eject the violators to make the risk of violation large.)
- For leads, they could have a different colored number banner on back add a horizontal stripe. They could print them with a different color to indicate lead is permitted no mask vs follow. (They could have a different color to indicate not tested.)
- As you suggested, they could wear a wrist band.
These are not either/or and I'm sure other options exist. So I think the rule will be fairly easy to enforce.
Honestly, I think if you take the test and fail, you should not be allowed to compete or dance. You and your partner would get your fee back. Of course, you'd still be stuck with transportation costs and possibly hotel. This policy would be severe. For pros a positive test would be a huge hit both because getting to compete is so important to them. It also would affect all their AMS. OTOH: their being infectious could expose all their AMs even with masks. I doubt it would be implemented unless the local authorities required it.
