Capital Oslo could announce the closure of schools from Wednesday this week, according to reports by national broadcaster NRK, which says it has spoken to relevant sources.
Children and young people in the city will face online classes for the “coming weeks”, according to the report.
The closure, which will not apply to kindergartens, is not yet confirmed, but the city council is expected to brief media later on Monday.
It is unclear whether the youngest age groups may be exempted from closures, NRK writes.
A total of 640 new cases of the coronavirus were registered in Norway during the last day, according to data from official registration system MSIS. The number is 214 fewer than the figure reported on Sunday but 271 more than the number on the equivalent day last week.
As of the early hours of Monday, 275 new cases of Covid-19 have been registered in Oslo over the last 24 hours. That is 87 more cases than were registered at the same point last week.
The last two weeks have seen an average of 221 new infections daily in the capital.
Some areas of the city – particularly the Stovner, Grorud and Alna neighbourhoods – have higher incidence rates than other locations, according to official figures. The three suburbs currently have respective incidence rates of 1,090, 1,047 and 922 cases per 100,000 residents for the last two weeks. The area with the lowest current incidence, Nordstrand, has 219 cases per 100,00 residents.
