There is a test called Biofire that can test for 18 viruses and 4 bacteria that can cause respiratory infection. Initial criteria was to rule out flu and have a negative Biofire before testing for Covid19. That rapidly changed to testing all at once. Hopefully soon Covid19 can be tested like the flu. There is still a possibilty he may not have it and I assume he had a Biofire test. The turnaround on the Biofire is less than an hour. There is also a possibility of multiple infections at once, although very low.COVID 19 is not bad in El Paso but other parts of the state are different. The good thing is that so far there is no evidence of community spread in Texas. Community spread is the big thing and we must do our part to stop that as much as possible, and that means no large gatherings. Another big problem is that a person can be contagious without having any symptoms. One of my former students who lives in Nashville is in quarantine and awaiting the results of his COVID 19 test. He tested negative for the flu so the likelihood of him having it is high. He would be a case of community spread.
Again, once we have a quicker and easier test that is more readily available and has a quicker turnaround, the statistics may stay the same, but will likely start changing for the better.
