The calculations presented Tuesday are based on methods developed by researchers at King’s College London. The data has been collected through the COVID Symptom Study app, which is also used for the same purpose in the US. USA App users are encouraged to report symptoms or lack of symptoms on a daily basis.
According to the figures presented The counties with the highest proportion of people with symptomatic covid-19 infection are estimated to be Stockholm, Södermanland, Västmanland, Gävleborg and Dalarna counties. It is estimated that between 3 and 3.5 percent currently have symptoms of disease. The lowest is found in Skåne, Kronoberg, Jönköping and Västernorrland, where an estimated 1.5 to 2 percent are infected.
However, the method used has a few drawbacks, among which only people between the ages of 20 and 69 are currently covered and there is a shortage of men using the app. Right now, researchers are looking for people from the target group of men and people over the age of 70. The study also did not detect people with a continuous asymptomatic infection.
– The greatest benefit of our calculations is that we will be able to observe trends over time and compare the epidemic in different counties. Our hope is that, as in the UK, we can provide daily updates to identify new “hotspots” before they can be detected in other healthcare monitoring systems, “said Maria Gomez, a professor at the University of Lund and one of the researchers behind the study in a press release.
