See, e.g., https://twitter.com/CT_Bergstrom/status/1479938658253766657. Policymakers are typically awed by the Power of Science and won't realize that these are garbage conclusions calculated from a garbage model of testing as a process blindly carried out every N days, for example with N=7 or N=14. @ct_bergstrom

When a case lasting 9 days is caught by a blind 14-day test, it has more than a 50% chance of being gone after another 5 days. Dress this up as a scientific report and it turns into government-policy decisions that mislead many people who were in fact tested for other reasons.

3. The CDC did not provide much justification for the decision, but this is the sort of question one can address with computer models. We (@RS_McGee, @ay_zhou, @hewillia34, David Brazel, and I) have spent the past ten days working on this. Here is an early peek at our findings.

Is there *any* scientific evidence behind the 5-day isolation period? I know of no single person that had Omikron that had a negative antigen test 5 days after testing positive; and all publications argue that you're infectious as long as your antigen is positive.

Why are the Swiss guidelines "5 days of isolation, 48h after cessation of symptoms", when obviously almost everybody is still infectious at that point?
