My father in law got hospitalized for dementia recently. He tested positive for COVID on admission, and was confined to an isolation room for 2 weeks (good insurance). He tested positive again upon his release to rehab. The tests are useless and meaningless. IIRC, the current "test" will report positive for Influenza A, Influenza B, COVID, or the spike protein for being vaxxed, Just another scam from those we are taught to trust the most.
