Here are some facts about influenza in the Netherlands in 2017-2018:
- 900.000 People got the virus in the Netherlands (official estimate)
- 340.000 cases identified by GPs
- 16.000 had to go to hospital
- 10.000 are estimated to have died (excess mortality)
What is the IFR of this monstrous virus?
10.000/900.000 = 1.11%!!!
This is the IFR, not the CFR, which would be:
10.000/340.000 = 2.94%
This in spite of us knowing the virus well, and having effective vaccinations for it.
During the 2017/2018 season 50% of at risk people and 18% of the population were vaccinated against the flu.
If vaccinations help, the natural IFR would have been up to 50% higher.
Therefore a bad flu season has a natural IFR which is greater than 1.1% according to the official statistics and best estimates.
This is 6 times higher than the best available estimates for the current SARS-COV-2 virus.
Which in the Netherlands puts the IFR (thanks to testing a lot) between 0.13 and 0.25%
