In Aktuellt, Per Follin is asked what the reduced number of cases may be due to.

- I think there are several factors. The fact that many have had the infection can contribute to a certain immunity. But also other factors. The restrictions that most people live by can be positive. We have limited travel and we have a summer season with heat that contributes to fewer respiratory infections, he says.

But he still does not think it's time to relax.

- You have to take it carefully, it can be a setback. It has been seen in other countries where restrictions have been reduced rapidly, where new peaks have been seen quickly. So I suggest you stick to the restrictions you have learned to live by.
