(Bloomberg) -- Norway advises people return to using face masks again on public transport and in shops, and will now require all adults to isolate for five days if they test positive for Covid-19, regardless of vaccination status.

The move extends the time that vaccinated people must remain in isolation from two days, Prime Minister Jonas Gahr Store told parliament on Tuesday. They are now also required to be fever free for 24 hours before going out again, while all adults in the same household must remain in quarantine until returning a positive test, he said.

The nation, which has been among the best to weather Covid-19 over the past year in Bloomberg’s Covid Resilience Ranking, has declined to 11th spot this month. With the omicron variant already detected in neighboring Sweden and Denmark, Norway is seeking to avoid going back into lockdown, while also preventing the health system from buckling. 

Accelerating the pace of vaccinations will help the country reach both goals, the prime minister said. He wants all those over 65 years old to receive a third dose by the end of the year, with a booster for all adults by mid-April. 

The government is working on tighter entry rules with health authorities and other countries, and will provide more information later on Tuesday, Gahr Store said.
