Tell the truth (yeah, like that will ever happen!).
Let people decide what is their own personal response.
Most people will do nothing. Otherwise healthy people below, say, 45-50 years old are reasonably safe. As long as everyone in this cohort avoids close contact with the elderly this should be OK.
People who assess the risk as high will plan and provide.
We've been hunkered down since early February, because mom is in her 90's, and I'm in my 60's. Pretty much only one weekly grocery run at oh dark hundred on Sunday and occasional scenic drives with no stops to ward off cabin fever.
We should urge our politicians to find out what kind of success/or failure the 3 Chinese clinical trials are having with using high dose intravenous Vitamin C to treat the acute respiratory syndrome phase of Covid-19.
Personally, I have taken 3 to 6 grams a day of C for over 45 years to deal with my allergies—house dust, cool weather molds, cigarette smoke, and ragweed. I vary the dose depending on whether my sinuses are blocked and sometimes sneezing. Vitamin C is anti toxin, anti histamine, and needed to grow our immune system white blood cells. ALso I space it out over every 6 or 8 hours. Recently I have increased my Vitamin D to 2000 to 5000 IU a day depending on seasonal sun exposure. Apparently D acts like a hormone affected around 2,000 of our genes operations. I got this recommendation from my son who is in Special Forces and has suffered from winter depression.
