Nicolai Tangen, chief executive of Norges Bank Investment Management, colloquially called the oil fund, informs on Thursday afternoon via LinkedIn that he has tested positive for SARS-CoV-2 infection.

"Today I tested positive for Covid-19. I took a test yesterday afternoon after feeling a bit under the weather, but my symptoms are mild. This means that I am now isolated in my apartment in Oslo where I will be working from for the next couple of weeks," the CEO writes on the social media.
