The only way to stop the virus is for the species to deal with it, either by developing a degree of community (aka herd) immunity to mute the worst symptoms/outcomes, or finding an effective vaccine and/or treatment. That is exactly to path we have been following. Doubling the testing will double the cases, as long as they keep up the 40 cycle RT-PCR test.
And they are adding test sites as though they need them. Local CVS now a custerbang to pick up prescriptions since they’ve become a drive through test site.
