This online interactive map enables users to track both the global and local trends of Novel Coronavirus infection since Jan 21st, 2020. The supporting dataset is timely collected from multiple official sources and then plotted onto this map.

Data Sources

The data are mainly collected from 1. National Health Commission (NHC) of the People’s Republic of China 2. China’s Provincial & Municipal Health Commission, China’s Provincial & Municipal government database 3. Public data published from Hongkong, Macau, and Taiwan official channels 4. World Health Organization (WHO) 5. Centers for Disease Control and Prevention (CDC) 6. Public Health Agency of Canada (PHAC) 7. Baidu. 8. the state officals of different states in the U.S. 9. NBC News. 10. New York Times The dataset (in SQLite format) can be downloaded from here. You can view the data (in CSV format) at here.

In the data table, each entry indicates the infection status in the format of "#-#-#-#" -- a 4-sequel entry divided by dashes. The first sequel represents the number of confirmed cases, the second sequel represents suspected cases, the third sequel represents cured cases, the fourth sequel represents death cases.

Update Procedure

The country-level data is collected from WHO, while the data of each province in China is collected from multiple sources such as China's NHC，Mapmiao and Baidu. Notably, we also refer to CDC to verify the virus spreading status in the U.S. To make a timely data and map updates, we collect the data every 4 hours, and verify the data quality per day. In addition, we plan to provide finer-scale data from China (the county level), U.S. (the state level) and Canada (the province level) in the next version.
