Probably that is true but combined with social distancing and other measures reducing colds and flu to a large degree. I also wonder if people are having the flu shot more? I know our company free flu shot scheme has had a far higher uptake this year.I haven’t seen stats but all my GP friends are saying that the number of “normal” infections they see, day to day, have fallen off a cliff. Although it’s possible that this is mainly driven by people suffering in silence, because they’re scared to visit their doctor.
