Officials in Moss, around 60 kilometres south of Oslo, confirmed earlier this week the localised outbreak with an increase in new cases during the last 14 days.
A majority of the new cases came from local transmission, rather than infection abroad and subsequent import.
Sarpsborg, southeast of Moss, has since been confirmed as the location of a wedding party linked to the Moss infections, VG reports on Wednesday. Broadcaster NRK writes that three celebrations were held in locations in Oslo and Sarpsborg between July 19th-26th.
Four further municipalities have been in contact with Norway’s national health authority, the Norwegian Institute of Public Health (NIPH) with regard to the wedding party, according to the report.
“We are not saying that the local outbreak started at the party, but three of (the infected individuals) from Moss were at the party. We have therefore worked to gain a record of all close contacts and follow up with guests to prevent further infections,” Kristian Krogshus, a senior consultant doctor with Moss Municipality, said at a press briefing on Wednesday.
People from the municipalities of Moss, Fredrikstad, Sarpsborg, Oslo and Råde were present at the events in question.
The last 14 days have seen 21 confirmed infections in Moss, constituting 15 percent of the 139 total new infections in Norway for the corresponding period, VG notes.
A total of 190 Covid-19 tests have been carried out on people in Moss over the last two days, while a spokesperson from Oslo’s health authority told NRK that no infections connected to the wedding party had so far been detected in the capital.
“We have spoken to four close contacts. Two of them have been asked to get tested, while the other two will see whether they get symptoms. The (latter) two must therefore avoid socialisation for ten days and be tested if they get symptoms,” Caroline Bremer of the Oslo Municipality Health Authority (Helseetaten) told NRK.
