Around 50 people have been infected with the new variant Omicron after attending a works Christmas party.
Staff at Scatec which is a solar energy company held the Christmas party on 26 November in Olso, Norwegian media reported.
The company is said to have an office in South Africa which saw some staff attend the party in Oslo from there.
Jorunn Thaulow, the district’s responsible infection control doctor, told Avisa Oslo, “We have not received it definitively confirmed, but there are very strong indications that it is Omicron in this outbreak.”
Assistant chief infection control doctor in Frogner District, Tine Ravlo, said preliminary screening shows there is “a high probability” of the new variant Omicron.
The staff who have tested positive with the virus are now in quarantine along with their close contacts.
