All manual updates (for countries and regions outside mainland China) are coordinated by a team at Johns Hopkins University. For city-level case reports in the USA, Australia, and Canada, which we began reporting on Feb 1, we rely on the US CDC, the government of Canada, the Australian Government Department of Health, and various state or territory health authorities. Before manually updating the dashboard, we confirm the case numbers with regional and local health departments, including the respective centres for disease control and prevention (CDC) of China, Taiwan, and Europe, the Hong Kong Department of Health, the Macau Government, and WHO, as well as city-level and state-level health authorities.

To identify new cases, we monitor various Twitter feeds, online news services, and direct communication sent through the dashboard.

For countries and regions outside mainland China (including Hong Kong, Macau, and Taiwan), we found DXY cumulative case counts to frequently lag behind other sources we therefore manually update these case numbers throughout the day when new cases are identified. About this data Sources: Center for Systems Science and Engineering at Johns Hopkins University and state and local health agencies (cases) World Bank and U.S. Every 15 min, the cumulative case counts are updated from DXY for all provinces in China and for other affected countries and regions. Our primary data source is DXY, an online platform run by members of the Chinese medical community, which aggregates local media and government reports to provide cumulative totals of COVID-19 cases in near real time at the province level in China and at the country level otherwise. As the outbreak evolved, the manual reporting process became unsustainable therefore, on Feb 1, we adopted a semi-automated living data stream strategy. During Jan 22–31, all data collection and processing were done manually, and updates were typically done twice a day, morning and night (US Eastern Time). The dashboard reports cases at the province level in China at the city level in the USA, Australia, and Canada and at the country level otherwise. The Lancet Regional Health – Western Pacific.
