This is not news. The same was already reported one month ago in the Italian village of Vo, where the entire population was tested for Corona. Summary is here: https://www.bmj.com/content/368/bmj.m1165 https://www.bmj.com/content/368/bmj.m1165 "In an open letter to the authorities in the Tuscany region,1 Romagnani wrote that the great majority of people infected with covid-19—50-75%—were asymptomatic, but represented “a formidable source” of contagion." In the same report was another interesting paragraph as well: He noted that Romagnani’s findings appeared to contradict a WHO report based on covid-19 in China.2 This suggested that “the proportion of truly asymptomatic infections is unclear but appears to be relatively rare and does not appear to be a major driver of transmission.” edit: really, downvoted? Because of the mentioning of China?
