Access to COVID-19–related Wikipedia articles in 2020 and the total number of deaths resulting from SARS-CoV-2 infection. (A) The percentage of daily article access (ie, the "COVID-19 pandemic," "Spanish flu," "Leonardo da Vinci," and "Sexual intercourse" articles) to English Wikipedia and total number of global deaths resulting from SARS-CoV-2 infection (ie, per 1 million people). Data for other language versions of Wikipedia are provided in Multimedia Appendix 4, Supplementary Figures S18-S25. (B) Heatmap of Spearman absolute regression coefficients for COVID-19–related articles and the total number of global deaths resulting from SARS-CoV-2 infection across languages and months. (C) Access to COVID-19–related articles (ie, the kNN-determined relevance values across selected Wikipedia language versions) versus the total number of region-specific deaths resulting from SARS-CoV-2 infection. The graph shows correlations between region-specific deaths and COVID-19–related articles. (D) Access to COVID-19–related articles (ie, the kNN-determined relevance values across selected Wikipedia language versions) versus the total number of global deaths resulting from SARS-CoV-2 infection.
