A total of 3,334 children under the age of nine, many of them with symptoms, were tested for the coronavirus to see if the reopening of kindergartens and schools last month, had caused an increase in infections.
This means that only 0.6 percent of the children tested had the coronavirus.
Many parents in Norway have expressed scepticism and fear that their children would be infected, saying they would keep their kids at home anyway.
Over the past month, experts have been closely monitoring developments, but so far there is little evidence that a new wave of infection is on the way.
According to the latest figures from The Norwegian Institute of Public Health, the infection rate from April 20th until now has been 0.61.
