No question you're correct about the rationale behind the extraordinary measures being taken to combat this virus. As it stands now, your suggestion that this virus is potentially more lethal is far from determined since there has been a piss poor effort to test and determine numbers who have contracted it although the death toll appears to be accurate. Hard to say this virus is more lethal simply based on the number of deaths versus the number of known infected when there are many estimates that the number infected could be 10 or more times higher than so far determined since in many cases - here in Canada as an example - if someone presents at a hospital with symptoms, they aren't necessarily tested unless they need immediate medical attention and are simply told to go home and self-quarantine for 14 days. Unless someone is in respiratory distress, they are neither tested nor treated - they could simply have the seasonal flu.
But my point remains - we seem, as a society, to be quite fine with letting 500,000 people every year die from the seasonal flu without instituting extraordinary measures to stop its spread yet social and regular media and government entities have generated a self fulfilling panic that demands their actions and vigilance. I believe, when it's all said and done, those same governments will be forced to review their actions by the same people who demanded such actions be taken. If millions of jobs are lost, thousands of businesses are bankrupted, and government revenues are hit as well as drained by these extraordinary measures, those in charge will be highly criticized and perhaps, rightly so.
One thing that is of benefit, however, is citizens are getting a taste of what life will have to be like if the climate zealots get their way.
