Epidemiological Curve of COVID-19 Cases in China From January 10, 2020, to April 18, 2020, by Daily Reported Data (http://www.nhc.gov.cn/xcs/xxgzbd/gzbd_index.shtml).

Note: From February 5, 2020, the increase trend changed. Shortly after the climax date (February 5, 2020), the extreme spike of cases on February 12, 2020, was explained by the change of diagnosis standard (The Protocols for Diagnosis and Treatment for COVID-19, Fifth Edition, in Chinese), in which clinical cases were included for reporting in Hubei province.
