My theory on why they want increase testing: increase testing brings increase in positives. You have to think that what we observe of this pandemic isn't the entire picture. We see worst cases that need hospitalization. In some country, since there weren't enough tests, only those with simptoms were tested. So you can assume that there were much more positives without simptoms. If you now change and extend the parameteres for testing and you perform more of them, you find more positives and so the pandemic seems growing but that's actually only because you are testing more
yeah, my bad but you should consider that the World is watching
