Data on malaria included in this study was extracted from the CISDCP system, which was established by the China CDC with open access from the Chinese Public Health Science Data Center [12] . The period included in the data was from January 1950 to December 2016. Population data for mainland China were extracted from the national data [13] . Province-specific population data were extracted from the China Compendium of Statistics [14] and the national data (2000-2016) [13] . Sex-and age-specific population data (data of 2010 were not available and were replaced by the intermediate value of 2009 and 2011) were also extracted from the national data [13] . Sex-, age-and type-specific data for malaria were available between 2004 and 2013. The number of indigenous malaria cases and deaths between 2017 and 2020 was estimated, from the annual per cent change (APC) values of indigenous malaria data between 2011 and 2016. No ethical approval for this study was required since the included data were publicly available and de-identified.
