It is a well known fact that without helpful bacteria in the gut, the immune function is severely dispaired. Yet almost no doctor EVER talks about the importance of probiotics or PRESCRIBES them to patients. All they are concerned about is the relief of symptoms. If we are as a society to face such outbreaks, it is imparative that we focus on the root causes and STRENGTHEN people physically and emotionally.
I would propose the following: instead of launching a scientific study if probiotics are helpful in fighting COVID19, prescribe multi-strain probiotics (harmless, widely available, cheap) to patients under treatment now and publicise the general positive effects of Probiotics.
I am not an expert on the subject, which is precisely why I have the necessary outsider perspective to the issue. I know it is very tempting to push aside the contribution of a non expert. But, this might just save the day.
After taking probiotics for about two weeks, the frequency with which I caught a cold(also a viral infection) came down by a factor of 12!
