So there is some good stuff here on the what COVID19 does and how we are fighting it and the values of social distancing.
In the UK we have seen how the government are trying to restricted the strain on the NHS so current cases do not overwhelm their resources.
Which makes sense, but what no one seems to want to spell out is that this current enforced social distancing will be the first of several.
Until a robust vaccine is produced, then the virus will keep spreading, social distancing slows it down. The best way to get through this pandemic will be for the healthy to catch it and breeze through it or be able to be treated by the Health services.
Once you have survived you will either be more resistant or even immune to further outbreaks. So you can now go about your daily lives (kinda).
So to keep those that suffer more from overwhelming the Health services, you impose social distancing and various lockdowns, then once the cases ease off you remove the distancing and lockdowns, let the virus spread again, infecting the healthy then go back into distancing and lockdown keeping the numbers down that the health services have to deal with.
So the cycles continue until either a vaccine or all the healthy have been through it and proven to be either immune or less vulnerable to repeat infections.
The above we think is termed herd immunity and is now we naturally fight similar if less deadly infections.
It also basically accepts that people will die, but the numbers kept down and is absolute pain and economic nightmare there is currently no other way of preventing more deaths.
What it fails to deal with is those that are at most risk, with current serious health issues. These cannot afford to catch COVID19 or they will most likely die, we are talking a minimum of 1.5 million people in the UK just over 2% of the population.
So until a vaccine with no side effects that affect their current conditions, is produced they have to remain in total isolation.
Things should get easier as more of the healthy populace recover from infection and can interact, but they will need a conclusive test that guarantees an accurate result. Before lifting the restrictions, especially if you come into contact with those at most risk.
Bottom Line = this isn't going away in a hurry
