Sweden is singled out as the worst at prescribing patients from IVA, keeping the R-number down and reducing the spread of infection.

This weekend, the report from the OECD was widely circulated in Sweden as well as in other countries.

But the OECD has made incorrect calculations for several countries when it comes to the number of tests per 100,000 inhabitants.

Backs after SVT's questions

The OECD has mixed up the number of tests performed per week and day for four countries, including Sweden.

- The value was seven times too high.

According to them, we were almost at the top when it comes to the number of tests and that is not true, says Anders Björkman, professor of infectious diseases at Karolinska Institutet.

After SVT asked the OECD questions about their calculations, they backed off. 

"It is a calculation error for Germany, the Netherlands, Spain and Sweden.

We will update the report in the next few days ", writes Guillaume Dedet at the OECD.

- It is frightening and astonishing that they let through these factual errors.

This shows a lack of insight into the covide epidemic, says Anders Björkman.

Tegnell: Incorrect conclusions

As previously reported, state epidemiologist Anders Tegnell is also strongly critical of the study and emphasizes that the OECD mainly deals with economic issues. 

- They have seen it as economic figures.

They have not understood the complexity of this data, he says.

Anders Tegnell is above all critical of the OECD's conclusions that Sweden has had major problems reducing the R-number, ie how many people an ill person infects on average.

- The measurement is made when Sweden increased the testing very much and the more you test, the more cases you find - then it becomes more difficult to get down the R number, says Anders Tegnell.

Whether the incorrect calculations affect other conclusions in the report is unclear.

- The covide epidemic is very serious and deserves better analyzes and opinions, says Professor Anders Björkman.
