One of Sweden's most populous regions has declared a "personal lockdown", as the country reported the highest daily rate of coronavirus cases in Europe.
The region centred on Uppsala, Sweden's fourth biggest city, has used posters and an online campaign to call on everyone to "consider all human contacts as a potential risk" and avoid contact with anyone they do not live with.
It is the closest the country has come to a lockdown since the pandemic began.
"We are reaching the point of the maximum capacity of what we can handle," Mikael Köhler, the region's health chief, told Sweden's TT newswire. "It seems like the British variant has taken over and there's evidence that people are spreading the disease before they have any symptoms."
