Thank you JL & MD. I think we still have a lot to learn and many questions unanswered about this disease. I don't think government experts or officials around the world are being cautious enough with many of their pronouncements and edicts affecting lives of the billions who are depending on them for safety and protection from this disease. Their continuing shortsightedness, irresponsibility and policy failures have the potential to create instability in a nuclear armed world which could destroy our civilizations. Yet they continue to play politics.
