| Sorry, if it was discussed here already. Isn't is suspicious, that the massive quick tests in Graubünden revealed the same 1% or infected, as in Slovakia? Is it some magic number for these kinds of tests? Did anyone read how many cases among this 1% in Slovakia were confirmed by normal PCR test? I've never seen this information on the news websites. And it seems that massive testing didn't help Slovakia a bit. So are these tests for screening purpose just a waste of time and money? | |

Why would this be suspicious?
Read an interesting back-of-the-envelope calculation for GR: 1% positive out of the 15000 who volunteered. GR has population of 200.000, so 1% would be 2000 cases. Assuming people test positive for 10 days before viral load gets small, you could say that is 200 per day. GR reports ca. 100 per day currently, so one could guesstimate that every second case goes undetected.
What these tests bring is another matter. You can certainly isolate the positive and ask their contacts to quarantine. Of the 15000, there will have been presumably 100-200 who just get infected a day or two before and who did not test positive yet. These people will be at the highest level of infectiousness right now just before developing symptoms.
