If you think it wasn't running through the population before China reported it, think about how reliable they have been about this whole thing.
In that time since the first real unidentified case of CV-19 and China doing something about it, how many deaths occurred due to "flu like symptoms" and blamed on, I don't know, the flu? How many cases of CV-19 were there before tests were developed to even identify, let alone name it?
After having considered the above, how many "infected" people with no observable symptoms, traveled all over, including the United States and Europe? As a result of that travel over the world, including its closest neighbors, like South Korea for instance, how many more were infected, showed no "observable symptoms, had a mild case of "the flu", or were hospitalized, or died before CV-19 was identified/tested for? Considering that this virus targets the most vulnerable, the elderly with compromised general health, how many died from reasons attributed to their health circumstances before CV-19 was on the radar? How many associates of the ill traveled in the general population as carriers before they showed any symptoms?
It was here, people, long before any cases were identified as CV-19. It is in the general population in more numbers than can be reported. Some of us have already had it because, in most cases, the symptoms are mild and we thought we had a "bug", or a "cold" or the "flu" or had no observable symptoms at all.
All this "general lock down" is probably too late. It might slow down the spread, hopefully it will, but the idea of "containment" has always been a futile joke.
The impact CV-19 has had on our lives is disproportionate to the nature of the threat and we have not reacted in this way in the past to any other infectious disease that I can recall. I can recall TB, polio, AIDS/HIV, hepatitis, Hong Kong Flu, bird flu, swine flu, any flu, etc.
I'm having a difficult time justifying the reaction and panic that the CV-19 outbreak has caused. Maybe if the death toll eventually climbs to a point that it rivals the diseases listed above, it might have been worth it, I don't know. I don't think we will ever know. If it doesn't, the powers that be will justify it by saying that their "responsible and timely action" prevented it from being worse than it was. If it does, they will say "we did everything we could but" . . .
Stop panic buying toilet paper.
