1/ A hang-up on rapid tests that I've heard is that it'll be difficult for health depts to track results

Decentralized screening makes that difficult but stopping spread should be the overwhelming priority; monitoring indirectly helps stop spread but is a secondary consideration

2/ We shouldn't hold up something that can stop transmission because it will be harder to monitor or collect data on

The current counterfactual is that we're missing most infections anyway & neither stopping onward transmission from them or getting any data on them

3/ What's generally been missing from the rapid testing discussion are counterfactuals

Anyone can point out issues that arise if using them but that is meaningless without considering what is happening w/o them & thoughtfully strategizing on how to address potential downsides

4/ Right now, thousands of people who are infected go undetected & are functionally 'false-negative' anyway

The restrictions we continue to live with also treat all of us as if we were infectious & therefore akin to being 'false-positive'
