Sweden has reported the highest rate of new cases in Europe, with a seven-day average of 587 new infections per million people on Monday, more than France on 556 and Poland on 540, according to the latest figures on Our World in Data.
The country currently has 395 patients being treated in intensive care, overtaking the 392 being treated at the peak of the second wave in January, although still below the 558 treated at the peak of the first wave.
Sweden has gradually tightened restrictions since the second wave took off in October, with pubs and restaurants forced to close by 8pm, visitor limits at shops, gyms and museums, and a recommendation to wear face masks in public transport during rush hour.
But it has never imposed the more thorough lockdown measures employed in France, the UK, or its neighbours Denmark and Norway, with Anders Tegnell, the country's state epidemiologist, arguing that lockdown measures were not sustainable in the long run.
"Basically, Uppsala is saying what we all are saying: you need to cut down on your personal contacts as much as possible, especially people that you don't normally meet," said Tegnell on Tuesday. "Since they have such a difficult situation, they need to enforce it even more. We'll see how useful it is."
He insisted that additional restrictions, such as shutting down restaurants, bars, gyms, and non-essential shops would have only "an extremely marginal effect", adding: "There are no new restrictions that could have more effect than the ones we already have. It's important that we follow them."
