The percentage of COVID-19 cases diagnosed in Spain rises to nearly 10% of the population
The figure forms part of the study of the evolution of the pandemic, based on mathematical models, being carried out with the support of the "la Caixa" Foundation by a multidisciplinary group of researchers from the UPC and the IGTP. The data show that there were at least 2.5-2.7 million accumulated cases in Spain on 26 April and 600-800,000 cases in Catalonia. According to the analysis, the delay between the appearance of symptoms and registration in the official statistics is between 10 to 14 days.
