I've heard of people submitting 5 covid tests that weren't used and getting different results back. But does anyone know of anything where people submit test made on inanimate objects? Maybe swabbing trees, or flowers? If the tests are faulty, then you would expect random results. In the rare chance they do test for some element, then it would vary based upon the environment. Street lamps along a busy sidewalk would likely test positive. And of course everyone who breathes that air, but doesn't mean either has some disease.
In the US, cases are increasing. So what. Are people getting sick? So what, if they are not dying. People get sick of all kinds of things.
But there is a glimmer of hope that case counts are going to plummet! Seems federal funds for the tests are about to run out.
