In Denmark, the spread of the coronavirus is increasing and a large proportion of cases are found in the country's second largest city, Århus, on Jutland's east coast.

Large share from Aarhus

When Denmark this weekend reported 207 new cases of covid-19, every fourth person who tested positive came from Aarhus. According to the city's mayor, Jacob Bundsgaard, a large proportion of the new cases are found in an ethnic minority group.

"About half of those infected come from the Somali minority group," he told DR. At the same time, he emphasizes that it is not yet known why the infection is so great right there.

In recent weeks, 104 new cases have been registered in Aarhus.

Suspects football celebrations in squares

Exactly what is behind the spread of infection is unclear. Experts point out, among other things, a football celebration last week when the football team AGF celebrated the bronze medal in the Danish super league as a possible cause.

About 1,000 people then gathered at the town hall square to celebrate the success without taking into account current restrictions.

Mayor Jacob Bundsgaard stated on Wednesday that the city is now tightening the rules further.

- We have reintroduced a restraining order on all nursing homes, he says to Danmarks Radio.

Tegnell: Risk of cluster spread also in Sweden

The risk of so-called cluster spread, ie that the infection spreads within a limited area or group, also exists in Sweden according to state epidemiologist Anders Tegnell. When the epidemic now moves towards a second wave, it is, among other things, local outbreaks that you will see, according to Tegnell.

- When the epidemic enters a second wave, it is quite a lot about this type of local outbreak, either geographically locally linked to some type of workplace or the like, so that risk exists in Sweden, says Anders Tegnell.

What tactics should we use to bring down these local outbreaks when they occur?

- The primary thing is to find them early, it is absolutely central. So much attention to the accumulation of cases in different ways, that you bring it out in the health care and the regions. That as soon as you see the kind of tendency that you contact us and start looking yourself, says Anders Tegnell.
