Where did ‘the flu’ go?

This graph is doing the rounds again.

But most sharing it don’t describe how you can verify it.

Pity.

Because “that’s a fake” is likely the first denial strategy the mind of many will deploy.

How to show that mind it’s for real:

  1. Go to the World Health Organization “FluNet Summary” page.
  2. Click: View FluNet chart for different time periods and geographic regions1Toward bottom of page. Oh, and I’m not sharing a direct link as the URL starts with “app.powerbi.com” and the doubtful mind would likely say “but that’s not a WHO website”. At least if you start them from WHO.int you’ve avoided that hurdle.
  3. Select your parameters2The settings Show chart > By date and Hide influenza positive specimens (%) are important if you want to reproduce exactly.

For instance, Combined surveillance graphs by country allowed generation of this graph for Ireland (2010-2023).

Now, about that Ireland graph. Why…

  • … no fuss about all the ‘cases’ in the 2010/2011 Winter season?
  • … hasn’t the normal Summer low happened in recent years?
