how about... we wear masks forever? because that’s the only logic if you’re bought into the 0 cases 0 deaths forever plan. there will always be cornavirus positive tests because the common cold contains coronavirus.... from the cdc website: https://www.cdc.gov/coronavirus/2019-ncov/testing/serology-overview.html

“However, there is a chance a positive result means that you have antibodies from an infection with a virus from the same family of viruses (called coronaviruses), such as the one that causes the common cold.”
