- They have to close because so many have fallen ill.

So far I know about 70 cases.

I don't want to speculate on what the illness is due to, says Johan Älvedal, the municipality's head of construction and environment.

It was a private person who got in touch when he felt unwell after visiting the hotel on the weekend of November 19-20.

The visitors have suffered from diarrhea and vomiting.

Staff are also said to have been affected.

"Must find the cause"

- I cannot answer when they can open again.

We have to wait for the test results and Villa Baro will take care of that.

We have set the requirement that they must find the cause of the infection before they can reopen.

The hotel's site manager, Ebba Adelswärd, has told the newspaper that they do not suspect that the infection originates from the food as some of the affected did not eat anything at the site, but only visited the premises.

She replied to SVT Nyheter Öst in an email that she did not want to give any comments "except that we are waiting for answers to the samples we submitted".

She also does not want to speculate on what causes the stomach ailment.
