LIVE UPDATES: Graphics of all Coronavirus cases, worldwide shown

Written by Johns Hopkins CSSE on March 4, 2020. Posted in Current News

Johns Hopkins CSSE are tracking the COVID-19 (corona virus) spread in real-time on their interactive dashboard with data available for download. They are also modeling the spread of the virus. Preliminary study results are discussed on the Johns Hopkins blog.

In response to this ongoing public health emergency, we developed an interactive web-based dashboard (static snapshot shown above) hosted by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University, to visualize and track reported cases in real-time.

The dashboard, first shared publicly on January 22, illustrates the location and number of confirmed COVID-19 cases, deaths and recoveries for all affected countries. It was developed to provide researchers, public health authorities and the general public with a user-friendly tool to track the outbreak as it unfolds.

Further, all the data collected and displayed is made freely available, initially as google sheets, now in a GitHub repository, along with the feature layers of the dashboard, which are now included in the ESRI Living Atlas.

The dashboard reports cases at the province level in China, city level in the US, Australia and Canada, and at the country level otherwise. From January 22-31 the entire data collection and processing was managed manually. During this period the number of updates were typically conducted twice a day, both morning and night (Eastern Time).

As the outbreak evolved, the manual reporting process became unsustainable, and on February 1, we adopted a semi-automated living data stream strategy.

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 COVID-19 cumulative case totals in near real-time at the province level in China and country level otherwise.

Every 15 minutes, the cumulative case counts are updated from DXY for all provinces in China and affected countries and regions.

For countries and regions outside mainland China (including Hong Kong, Macau and Taiwan), we found DXY cumulative case counts to frequently lag other sources; we therefore manually update these case numbers throughout the day when new cases are identified.

To identify new cases, we monitor various twitter feeds, online news services, and direct communication sent through the dashboard. Before manually updating the dashboard, we confirm the case numbers using regional and local health departments, namely the China CDC (CCDC), Hong Kong Department of Health, Macau Government, Taiwan CDC, European CDC (ECDC), the World Health Organization (WHO), as well as city and state level health authorities.

For city level case reports in the U.S., Australia, and Canada, which we began reporting on February 1, we rely on the US CDC, Government of Canada, Australia Government Department of Health and various state or territory health authorities. All manual updates (outside mainland China) are coordinated by a team at JHU.

We are currently in the process of conducting additional modeling of this emerging outbreak, and will update this blog post with the results soon.
