Evidently there is a world wide shortage of chemical reagents needed for testing. While testing capacity has increased a major bottle neck has developed:

"The current trouble is a critical shortage of the physical components needed to carry out tests of any variety. Among these components are so-called viral transport media, which are used to stabilize a specimen as it travels from patient to lab; extraction kits, which isolate viral RNA from specimens once they reach the lab; and the reagents that do the actual work of determining whether the coronavirus that causes covid19 is present in the sample."

As the virus spreads and Health Care Professionals get more experience in treating patients with the virus, it appears TO ME that the diagnosis may just have to come from the Doctor. In short, I fear that the information on this virus will not be available or understood for years to come. In the information age, we are going to have to muddle through with what we have on this one I fear.
