Weekly flu patient counts overlaid across seasons, aligned by week of season. Flu seasons tend to fall into a few shapes — an early peak, a late peak, or a low slow burn that finishes late. As a new season arrives week by week, this shows which past season it most resembles so far — a starting point for modelling. Charts are computed in R, in your browser, via webR.
⚠ Showing illustrative, synthetic data — not real NHS figures. See the README for how to drop in real NHS England weekly flu data.
