” Anders Bjorkman, a leading epidemiologist who spent years at the forefront of malaria research, challenges the model used by researchers at Imperial College London, which estimated that about 1 per cent of those who contracted the virus would die. He argues that the estimate is misleading as it does not include those with the virus who exhibit no symptoms.
“They say there’s 1 per cent mortality. That’s not true. They completely discard the asymptomatics,” he said. “In all these groups there are some who don’t have symptoms and aren’t reported. In Sweden the average age of all reported corona cases is 56 years roughly. The average age of the population is 40 … and I believe that all age groups have been more or less equally exposed. Among the younger population, those under 40, there are so many non-symptomatics.”
The death rate in Sweden, he said, was likely to be closer to 0.1 per cent than 1 per cent. Hundreds, rather than tens of thousands, would die before herd immunity was achieved.
The public health agency said that in tests of about 5000 people who had returned to Sweden from visits to Italy, the few hundred that were positive all exhibited mild symptoms — implying that there could be a large number of people in Sweden who are asymptomatic — with mild or no symptoms — who have not sought medical treatment.”
