It comes as Swedish authorities are warning of a rise in the number of cases after a long lull during summer. This rise and fears of a second wave have prompted the government to push back plans to raise the limit of attendees at seated events, and the Public Health Agency to introduce new stricter rules for family members of people with Covid-19.
At Tuesday's press conference, Sweden's chief medical officer said it was hard to draw conclusions from the recent rise in intensive care figures however.
“These are such low numbers that it is hard to say if it's a break in the trend or a temporary jump,” said the National Board of Health and Welfare's Thomas Lindén.
State epidemiologist Anders Tegnell said: “Some people are in intensive care for a long time, while others are only there for a short time, so I wouldn't call this a break in the trend, although it is absolutely an important signal to keep an eye on.”
