Q: What is the workload like? Do you work in shifts?Ī: For over 2 months, we were trying to make decisions on where to collect data from, what data was trusted, how to aggregate it, validate it. But the group is still way smaller than it should be for what we're doing. People at Hopkins manage the media and communications. Esri, the company that has the mapping software, helps manage the platform. Now, the Applied Physics Lab helps with the back-end data curation and tech. Because we were blowing up Amazon servers with all the demand. But early on, Hopkins reached out and offered support internally. There's nothing at a county level.Ī: At first, it was my group, which is about six people. ![]() But they only provide state-level data, and it's sometimes a 24- to 48-hour delay. data from the Centers for Disease Control and Prevention?Ī: You would think so. What I would like is for all the different local health authorities to keep improving their own reporting in a way that we can draw the data directly from them rather than from local media reports. But the thing is, if there is a loop no one's reports would ever increase. We have to be really careful to only reference their national data. data from them, and they pull global data from us. There is a media aggregation site for the United States called 1point3Acres that we follow really closely. We'll get told, "Hey, there's two new cases here that you don't know about." We also now have an anomaly detection system in place that alerts us to discrepancies in the case reports that we automatically collect. So, if we're off, people reach out and contact us very quickly. How do you make sure it's accurate and not double counting?Ī: There are millions of eyeballs on it all the time. Q: The dashboard draws on hundreds of sources, from WHO data to sites that aggregate news stories and social media reports on COVID-19. And the next day I shared it on Twitter, and it immediately became popular. In a few hours, we built the original dashboard. My grad student Ensheng Dong, who is Chinese, was personally interested. We started this in January when the outbreak was pretty much just in China. How did yours come out on top?Ī: Probably because it's been around the longest. Q: There are a lot of sites tracking COVID-19 cases. This interview has been edited for clarity and brevity. Gardner spoke with ScienceInsider on Friday, 3 April, the day after COVID-19 cases surpassed 1 million worldwide, with more than 50,000 deaths. ![]() Department of Health and Human Services's coronavirus war room.īehind the site is Lauren Gardner, co-director of Hopkins's Center for Systems Science and Engineering, whose previous work involved spatial modeling of epidemics of measles and the Zika virus. It has been spotted on a wall in a photo of the U.S. Its dashboard has been copied by states and countries. It is used by news organizations and government agencies around the world. Yet the site, which gets more than 1 billion hits a day, has become the most authoritative source for COVID-19 case data. ![]() With its black world map strewn with red circles and global, country, and state counts of cases, deaths, and recoveries, the Coronavirus COVID-19 Global Cases tracker sticks to the basics-no fancy graphs. But one of the earliest, an online dashboard run by Johns Hopkins University, has become the go-to place for the latest data on coronavirus disease 2019 (COVID-19). ![]() Many websites track the devastating spread of disease and death caused by the now-pandemic coronavirus, from the World Health Organization's (WHO's) global map to The New York Times's tally of U.S. Science' s COVID-19 reporting is supported by the Pulitzer Center.
