Please wear a mask when you are out. Even though there may be a treatment for Coronavirus using steroids, you still don't want to go there. And all that we know about Quinine in the time of Coronavirus is that it became a reason, or excuse, to drinkGin and Tonics, which are essentially quinine containing tonic water with some amount of gin and usually a squeeze of lime. It was prevalent in the 1950s as an antidote for malaria.

But really, even though masks are a pain, and it hasn't been that long since half of us gave up the misery of wearing proper (meaning restrictive) foundation garments,
the use of masks is something you can get used to. The effectiveness of masking increases greatly for everyone as more and more people do it. At least, if you are ill, wear a mask. This has been considered good manners in certain parts of the world for some time; a common courtesy to not spread a cold.

A mask is like a mini way of isolating, because it can be unknown who is sick. "Insist that when someone is ill that he or she takes proper precautions and gets proper care.", L.Ron Hubbard.
