Right now, there is a greater spread of infection in society than there has been before during the summer, and it seems that people have brought home the more contagious Delta variant from abroad. 

- In the past, most people who have been infected have been people who have been abroad, ie people in their 30s and 40s and their children.

But last week, most of the people who became infected were 20-29 years old, says Anders Lindblom who is an infection control doctor in Dalarna.

Important with sampling

- It is important, as we have said so many times before, that if you feel sick or are ill with mild symptoms, you should try, even if you are vaccinated.
