COVID-19 cases in Collin County, TX, are shooting up... but this appears to be driven by a recent surge in testing. The County now reports about 3000 tests/day, up from 1000/day just last week. This drives positivity rate from 16% to 7%. Will take time to settle this out. https://twitter.com/drsekula/status/1292977584683266049/photo/1 https://chirp.cooleysekula.net/attachment/66991
