Good pickup. As we have said previously, viruses mutate and the tragic thing is that they mutate often in response to the treatments so the "little bastards" try to slide over to stronger forms that kill even more people and do it more easily and quickly. It is a fact of science and we should thank God for rapid diagnostic technologies that can be used in the difficult environments in which such diseases are brewing. I wonder what little company has a patent on the best and most rapid technology with the most robust strength of packaging? Could it be?
