It would be nice if we could learn something about how to keep flu levels low without taking drastic pandemic level action: hand washing might help a bit.
I had a look the other day at the national flu surveillance reports, and flu rates are extremely low... higher than the virtually non-existent flu levels of last year, but far, far lower than in 2019 and prior years. The predictions of a duel influenza-Covid fuelled crisis hasn't come to pass.
Given that restrictions in schools and other places have been lax through the autumn I'm surprised...
I wonder whether most of the flu cases are picked up when they become serious.... and that tends to be those in care homes and the vulnerable in the community, both of which have been far more diligent at reducing infection than they were pre-2020.
