Publication year within an outbreak: 2003 (SARS-CoV), 2014 (Ebola virus), 2015 (MERS-CoV), 2016 (Zika virus), 2020 (SARS-CoV-2). All guidelines of Zika virus and SARS-CoV-2 were published in the same year, the data cannot carry out subgroup analysis for the publication year since outbreak. *, Kruskal-Wallis Test was used due to uneven variance. †, publication year within an outbreak: 2003 (SARS-CoV), 2014 (Ebola virus), 2015 (MERS-CoV), 2016 (Zika virus), 2020 (SARS-CoV-2). t, t value of Student’s t-test; F, F value of analysis of variance; H, H value of Kruskal-Wallis H test; SARS-CoV, Severe Acute Respiratory Syndrome coronavirus; EBOV, Ebola virus; MERS-CoV, Middle East Respiratory Syndrome coronavirus; ZIKV, Zika virus; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; CDC, Centers for Disease Control and Prevention of the United States; Chinese Center for Disease Control and Prevention.
