The Norrbotten Region's infection control doctor, Anders Nystedt, is deeply concerned about the development.

- Haparanda has had a large spread of infection for a few weeks now.

It is a very worrying situation, he says to Haparanda city's website.

Urges not to visit anyone

The city of Haparanda now urges all relatives not to visit their nursing homes and Nystedt emphasizes that it is now up to everyone to take their responsibility.

- Do not visit your siblings, your parents or your friends.

Do not visit anyone!

Stay at home, he says.

The infection control doctor also points out that a large spread of society means, automatically, that there is a great risk that more people will become infected - not least in elderly care.
