- Locally, it can have quite large consequences that we have less chance of finding outbreaks in time and that we actually have a worsened infection surveillance.

It is well about prioritizing resources that I understand, but I think that there is a great risk here when you prioritize in this way, says Tove Fall, professor of molecular epidemiology.

In both Norway and Denmark, mass testing of the population is currently a priority for covid-19.

A measure to curb the sharp increase in the spread of infection in the two countries by detecting the infection early.

But in Sweden, the Swedish Public Health Agency has, on the contrary, decided that vaccinated people - from 1 November, will no longer be offered free PCR tests - with certain exceptions for, for example, healthcare staff.

However, many regions state that it is difficult to check whether the person booking is vaccinated or not.

The infection control doctor: We are probably traumatized

Uppsala follows the authority's recommendations.

The infection control doctor in Uppsala, Johan Nöjd, is afraid that regions that do not follow the recommendations may risk losing the compensation for testing from the state.

- We infection control doctors are probably a little traumatized by the whole pandemic and the virus has surprised us time and time again.

So it is clear that it would have felt a little safer to follow it more closely for another time, says Johan Nöjd, infection control doctor in the Uppsala region.

Professor: Sweden will get the fourth wave

In just one week, testing decreased significantly in Sweden.

Last week, just over 86,000 people in Sweden were tested for covid-19 symptoms, a decrease from 121,000 people who tested themselves the week before.

At the same time, several regions are seeing tendencies towards an increased spread of infection, partly due to the fact that the proportion of positive test results has increased.

In Kalmar, for example, ten percent of PCR samples now show signs of covid-19, twice as much as just a few weeks ago.

Anders Vahlne, professor emeritus of clinical virology, who has previously criticized Sweden's strategy, is convinced that the reduced testing in Sweden will lead to a greater spread of infection.

- I think it's very unfortunate.

Of course, we see that we will get a fourth wave in Sweden.

So it is now that we should be proactive and not reactive when we are faced with a situation full of patients in hospitals, he says.
