One thing that concerns me, maybe unnecessarily... is that even if all this handwashing, masks, social distancing etc. actually does make a difference... what will people's immune systems do next year?
I would expect flu deaths to go down this winter, as we have lost thousands of the most vulnerable already...
But I wouldn't be surprised, if in 6/12 months, we have a lot more deaths and problems with auto-immune problems, like asthma, hay fever, allergies, anaphylaxis... etc. As well as people being more ill from usually milder problems.
