Norway’s health authorities have doubled down on their recommendation for those without symptoms not to wear face masks, arguing that the number of infections in Norway was now so low that they were unnecessary.
In a memo, published in English on its website, the Norwegian Institute of Public Health, said that even in the best case, with medical masks which prevent 40 percent of infections, 200,000 people would have to wear them to prevent just one new infection per week.
This, it said, meant that the likely negative impacts outweighed any benefits “in the current epidemiological situation”.
