What positives can we make of the situation we are in.
We currently don't know how this virus will evolve.
Worst case scenario, it remains deadly for a number of vulnerable groups, at current levels (I've seen 1 in seven dying, being quoted for older people with underlying health issues), and we can't / don't develop an effective vaccine.
Like seasonal flu, but with fins on.
The above being beyond our control.
We currently have no immunity to Coronavirus ; get exposed, get infected. Some will die. Thankfully, most groups will recover (and hopefully, develop immunity). Once immune, while you can still spread the virus, you can't catch it (obviously).
When enough people have been infected, survived, and developed immunity, the ability of the virus to rapidly spread is blunted (because there's very few people without immunity to spread it to). This is termed "herd immunity", and protects the vulnerable.
If this becomes the case, phased and controlled exposure to Coronavirus makes some sense. Total lockdown prevents herd immunity from developing, while doing nothing allows it to spread like wildfire, killing far more (because the health service would be overwhelmed).
That's my understanding of it anyway.
So, the silver lining? If the above comes to pass, we lose fewer of our loved ones, and are much more immune as a country when the next outbreak comes around.
Again, that's my understanding of it anyway.
