It may help some who haven't thought about it, or even forgotten. With this virus you can have a very bad sore throat I believe, some will, some won't. Good old T.C.P to gargle with will help, may be a good idea to get some in, not many people buying it and seems to be plenty in the shops at the moment. :0)
I doubt TCP will help and if you don't mind me saying (but you probably do but what the heck) you seem to be completely obsessed with Covid. Let it go.
