Resolves according to the number of reported cases published by the World Health Organization

Updating a bit (and trying less hard on the stats):
From previous GW wrapups
Year: 2020, 2021, 2022, 2023, 2024, 2025
Total case count: 27, 15, 13, 14, 15, 10
Year: 2020, 2021, 2022, 2023, 2024, 2025
Case count up to September: 24, 11, 9, 9, 7, 10
Diffs: +3, +4, +4, +5, 0
Average diff is 3.2±1 using sample sd of diffs.
Ratios: 1.125, 1.364, 1.444, 1.556, 1
Average of ratios is 1.3
My intuition is that the ratio method is more accurate - after all, the thing that's happening is that we are looking only at the GW cases in the first 2/3 of the year.
My 2024 prediction ended up too low, by like 5 cases. But done on 2025, I'd have ended up too high by like 3.
Current wrapup data for this year is up to July, with 4 cases. That's less than in previous years: up to July, 2023 had 6, 2024 had 9, 2025 had 6.
So, I'd be surprised if we got 15 again. I think my prediction is 10.
