What did you get right in late Feb that the WHO and such were still wrong about? I feel like by that time it was already fairly clear from their communications that this was going global and heavily affect everyone.
Where WHO and others were mistaken in their communication was where they were discouraging use of facial covering. And I meant only that here. AFAIR, they were very correct about the severity of the disease. Unlike ECDC[0]; I read their reports too, and AFAIR, they were still only predicting moderate risk for Europe as late as second week of March.
