In the last two weeks, Norway’s capital has registered 22.49 infections per 100,000 residents, according to newspaper VG's tracking of the data.
The Norwegian Institute for Public Health (NIPH) regularly updates its list of EEA and Schengen area countries which meet and do not meet the country's criteria for safe travel, and the government bases travel guidance on this.
Countries are added to the “red” list of non-advisable destinations when the number of new cases in the previous two weeks mounts above 20 per 100,000 inhabitants.
There must be less that 20 cases per 100,000 during the past 14 days for a country to be “green”.
“There has been a general trend amongst all of the public during the summer towards being a bit more lax about following the rules,” infectious disease senior doctor Frode Hagen said in an Oslo Municipality press statement.
“It’s important that we try to tighten up again now the holidays are over and we are getting back to normal routines,” he added.
Oslo is one of six municipalities across Norway with increasing infection rates. The others are Indre Østfold, Lørenskog, Bodø, Lillestrøm and Trondheim, according to VG’s report.
Data from the Norwegian Directorate of Health also shows an increase in hospitalisations with the virus, from 3 on July 31st to 16 on August 10th. The figure is a national count for Norway.
