No, the virus can't be beaten 100% by the health department guidelines. That's not how viruses act, and even a vaccine isn't likely to be fully effective if this virus can mutate like many others do. Flattening the curve is about getting it to a controlled level where healthcare facilities aren't overwhelmed, testing is adequate and we aren't on a runaway train. That doesn't mean 0 cases. But it means much, much better than over 10,000 new cases per day just in the state of Florida. We also need to better understand how to treat with early intervention to prevent cases from getting critical. Personally I think more effective treatment is a likelier solution than a vaccine, but let's hope I'm super wrong about that.
And we know that the virus can be adequately controlled by social distancing and hygiene measures, because we saw the improvements happen here and in other areas. Unfortunately, once the heavy lockdowns were eased here in Florida people and businesses refused to follow safety guidelines. And now we're looking at over 10,000 new cases per day and hospitals reaching capacity again. Again, the epidemiolgists said we shouldn't need to lock down again, if we all behave responsibly. So far people refuse to do so, then they complain about the consequences.
And I am grateful to people like you. If everyone would only do their small part we could all have a brighter outcome, faster. Mainstream as my opinion may be, I don't think you and I are really that far apart in our views. I want the best of all of us and that includes the ability to feed our families.
