This may be an important new clue:
Lost Sense of Smell May Be Peculiar Clue to Coronavirus Infection
The New York Times - March 22, 2020
A mother who was infected with the coronavirus couldn't smell her baby's full diaper. Cooks who can usually name every spice in a restaurant dish can't smell curry or garlic, and food tastes bland. Others say they can't pick up the sweet scent of shampoo or the foul odor of kitty litter.
Anosmia, the loss of sense of smell, and ageusia, an accompanying diminished sense of taste, have emerged as peculiar telltale signs of Covid-19, the disease caused by the coronavirus, and possible markers of infection.
On Friday, British ear, nose and throat doctors, citing reports from colleagues around the world, called on adults who lose their senses of smell to isolate themselves for seven days, even if they have no other symptoms, to slow the disease's spread. The published data is limited, but doctors are concerned enough to raise warnings.
My approach; I wash my hands properly upon leaving and entering my home. (Povidone-iodine solution may be useful too).
I am now taking:
~6,000IU Vitamin D3
30mg Zinc Gluconate
500mg Vitamin C, twice a day (this is a low amount)
1,000mcg Vitamin K2
250mg Niacinamide (not just 'niacin')
1 'One-A-Day' high quality vitamin combo
(The high vitamins D3, vitamin C, and probably zinc gluconate are the most important, and should be started before the virus is encountered.)
I'm no doctor, but that is what I am taking.
Some medical doctors are emphatically stating that high-dose intravenous vitamin C has been the best cure in China.
There appears to be rather strong reason to believe that (soon-prior use of?) the pain medicine ibuprofen can actually cause the coronavirus pathology (which I say should be referred to as 'CVP19' not 'VD'!) to be more severe. This also applies to SOME medicines used for hypertension and for some cases of diabetes (type 1 and type 2). Source:

(Search down to 'ibuprofen'.)
Any soap or detergent is sufficient concentration will destroy lipid components which the coronavirus requires in its envelope (this will destroy it). So nothing special is normally needed. You can wash hands with a bar of soap if you lather up reasonably well, and leave the soap on for about 20 seconds.
You 'PROBABLY' can disinfect face masks by dipping them in a bowl of 3/4ths water and 1/4th not-too-smelly (maybe lemon) dish detergent. Then rinse it off with plain water. You can re-use the bowl of water and detergent.
'Ask your doctor', as I am definitely not an expert in virus control!
