Let's take a look at May 5th data from a more detailed source. https://www.worldometers.info/coronavirus/country/sweden/ May 5th had 495 new cases and 85 new deaths in Sweden May 4th had 404 new cases and 90 new deaths in Sweden May 3rd had 35 new cases and 10 new deaths in Sweden May 2nd had 562 new cases and 16 new deaths in Sweden May 1st had 428 new cases and 67 new deaths in Sweden
May 5.. wikipedia says the data for this chart comes from the Public Health Agency of Sweden. It reads 18 new deaths. Your source says 85. that is a big difference so where worldometer get the data? "Antal fall av covid-19 i Sverige - data uppdateras dagligen kl 11.30". Public Health Agency of Sweden – Official statistics at arcgis (in Swedish). Public Health Agency of Sweden (Folkhälsomyndigheten). 30 March 2020. Retrieved 9 April 2020. Lay summary – Antal fall av covid-19 – Statistik – antal fall covid-19. Data updated daily at 11:30 [CET]
