Reuters and AFP news agency reported on the 5th (local time) that at least 13 out of dozens of people who tested positive for COVID-19 after attending a company’s Christmas party in Oslo, the capital of Norway, were recently confirmed to be infected with Omicron.
The Norwegian Institute of Public Health (FHI) said the previous day that 13 people involved in the party had been confirmed to have been infected with Omicron.
On the 26th of last month, a company’s Christmas party was held in Oslo, Norway with about 120 people in attendance.
Since then, about 60 of the attendees tested positive for COVID-19, and one of them was confirmed to be infected with the Omicron mutation.
As a result, local authorities conducted gene sequencing of other confirmed COVID-19 patients who attended the party, and confirmed additional infections with omicron mutations.
As analysis is still ongoing, the number of omicron-mutated infections may increase.
“This party is a super-transmission event,” an FHI official told Reuters. “Our hypothesis is that at least half of the 120 attendees were infected with the Omicron mutation during the party.
The official added that this would be the largest case of Omicron infection outside of South Africa.
The total number of confirmed cases of Omicron in Norway has risen to 19.
Of these, four had traveled to South Africa.
In the Netherlands, 18 of two passengers on a plane that arrived from South Africa last week have been confirmed to have been infected with Omicron, Reuters reported.
The Dutch National Institute of Public Health and Environment (RIVM) made this statement on the 4th and said that the investigation into the passengers of these two airliners has now ended.
In the Netherlands, 61 out of 600 passengers on the two South African airlines that arrived at Amsterdam Schiphol Airport on the 26th of last month tested positive for COVID-19 immediately after landing.
Afterwards, additional confirmation procedures were carried out for these confirmed patients to determine whether they were infected with Omicron.
