From a few isolated confirmed cases this summer, to around 100 elderly people receiving a positive test result for a week at the end of September.

Even though it is still low levels, the curve is pointing in the wrong direction.

The same applies to deaths with covid-19 in special housing, Säbo.

Hardly a single death a week during the summer, now at the turn of the month 26 dead in a week.

- It's a little worried.

At the same time, we know that if you are fully vaccinated, it is a very strong protection against getting a serious illness, says Ingmar Skoog, professor of psychiatry and director of the Center for Aging and Health at the University of Gothenburg, in SVT's Aktuellt.

Risk to benefit

He adds that some of those who are fully vaccinated get a serious form of covid-19.

- But in individual cases, I do not think you should be so worried.

If we are to weigh the risk and benefit of isolating people as we did before against being able to meet relatives and live a fairly normal life, then the benefit of continuing is much greater right now, says Ingmar Skog.

If the infection continues to increase - can it be time to reverse the band and return to isolation of the elderly?

- This pandemic has everyone had a hard time predicting what will happen.

But based on what we know and if you now get a third vaccine dose as well, we should not have to do it.

It is such an intervention with isolation and a restraining order, he says.
