Gastroenteritis #Seasonality

Smear infections. No droplets, no aerosols.
Noro autumn/early winter, Rota sping/early summer.

Can we explain this by "being indoor" or the weather? Or is our body following a seasonal pattern of immunological activity?

Remeber any Rota-lockdowns?

Let me add Campylobacter (bacterial) Gastroenteritis. Peaks in late summer each year. So steady, you could use it as a calendar.

Most human infections occur in distinct cycles.

And, dear epidemiologists - can you please explain how these patterns are explained by your beloved SIR models? Why are you still using these, knowing that they *never ever* made a correct prediction?
