Coronavirus Disease 2019 (COVID-19) Cases Tracker
This web map is an open source version of the COVID-19 global cases website by Johns Hopkins CSSE. It uses OpenLayers for mapping, Plotly.js for plotting, and Iconify for icons.
UPDATES
As of December 10, 2020, I stopped updating my demo site because, unfortunately, there is too much data to process and upload to the server. Also, the client-only model doesn't seem to work smoothly at this point. It became too slow to be practical. It wasn't expected at all when I started writing this code early this year.
Single-country maps are now supported:
As of March 27, 2020 at 6pm EDT, fetch_data.py's count of the United States cases is 697 greater than CSSE's. I checked individual states and created the following table:
| County | State | CSSE CSV | CSSE REST |
|---|---|---|---|
| Coffee | Alabama | 1 | 0 |
| Fairbanks North Star | Alaska | 11 | 10 |
| Cleburne | Arkansas | 47 | 46 |
| Dawson | Georgia | 3 | 2 |
| Unassigned | Hawaii | 8 | 6 |
| Bannock | Idaho | 3 | 2 |
| Bingham | Idaho | 2 | 1 |
| Unassigned | Illinois | 668 | N/A |
| LaSalle | Illinois | 3 | 0 |
| Logan | Illinois | 1 | 0 |
| Ascension | Louisiana | 91 | 90 |
| Morehouse | Louisiana | 3 | 2 |
| Jackson | Michigan | 17 | 16 |
| Newaygo | Michigan | 2 | 1 |
| Amite | Mississippi | 1 | 0 |
| Houston | Tennessee | 3 | 2 |
| Guadalupe | Texas | 9 | 8 |
| Walker | Texas | 3 | 2 |
| Unassigned | Vermont | 8 | 6 |
| Norfolk | Virginia | 9 | 8 |
| Fairfax City | Virginia | 1 | 0 |
| Unassigned | Washington | 69 | 67 |
| Preston | West Virginia | 2 | 1 |
| Ohio | West Virginia | 2 | 1 |
| Hancock | West Virginia | 1 | 0 |
Data from the REST API is supposed to be current because their web map directly uses this data for visualization, but some of those numbers are decreasing for some counties in the United States. I have no idea which version to trust more between their daily reports vs. REST data.

Data Sources
- Main data source: CSSE's time series data and REST API
- China: DXY
- South Korea: KCDC
- Italy: StatisticheCoronavirus
- Chile: Minsal
I found CSSE's data unreliable because they keep changing country names and adding duplicate entries with incomplete records. I am trying to clean up their data as much as possible to avoid double counting (e.g., as of March 17, Guam vs. Guam, US and French Guiana vs. French Guiana, France), so there can be some discrepancy between my cleaned up data and their original data.
Data Files
- geodata.json: GeoJSON file with case locations and time series data
- data.csv: CSV file with the same information in a tabular format
