aKeywords were used to collect relevant data for each country. We used two kinds of keywords: one official naming of COVID-19 and Wuhan as an unofficial representative naming of the virus. Keywords listed here are translated in English from the actual local language (eg, “코로나” means “Corona” in Korean). The original keywords in local languages are listed in Table MA1 in Multimedia Appendix 1.
