Online Map Tracks COVID-19 Testing Stations Throughout U.S.

Newswise — As the COVID-19 coronavirus began to spread abroad and then within the United States, Johns Hopkins Carey Business School Associate Professor Jim Kyung-Soo Liew determined to join the fight against the pandemic by putting his expertise in big data and artificial intelligence to work. 

With the help of a data-gathering team comprising scientists from his software company and student volunteers from Johns Hopkins Carey Business School, Liew created a map that tracks drive-through testing stations across the U.S, including Alaska and Hawaii.

In the following Q&A, Liew explains how the mapping project originated, how it works, and why he believes it provides a valuable service during the crisis.

QUESTION: Can you describe the purpose of the project?

JIM KYUNG-SOO LIEW: We are tracking data on drive-through COVID-19 testing stations, because this method of testing, we believe, is the safest one presently available. By testing people who remain in their vehicles, the chance of infection to the health care worker is greatly reduced. This model of testing is also efficient: As soon as the service is complete, the individual simply drives off, and the next individual pulls up.

How did the project come about?

It pieced itself together as I was following the COVID-19 outbreak in South Korea with intense concern, as my brother-in-law and his family live on the U.S. military base in Daegu, South Korea. As I followed the news reporting on how South Korea was responding to the outbreak, I was intrigued by the efficacy of their drive-through testing kiosks in detecting and containing the spread of the virus and therefore “flattening the curve.”

Since I employ a team of data scientists for my machine learning and artificial intelligence full-stack software company, I turned to them to help me rapidly build and deploy a map showing all drive-through testing kiosks operating in the United States. Fortunately, I was prepared to deploy this task quickly since I have done research using latitude and longitude data.

The map is updated several times a day and is being heavily promoted on social media sites such as LinkedIn and Twitter.

How is your team compiling the data?

To get the project off the ground quickly, my team initially compiled the data by hand. As the number of sites increased rapidly, I expanded my team to include 50 volunteer students from Carey. The volunteers search for drive-through kiosks across the U.S. by perusing online local news sites and input that data into a form. The form populates a database, and the data renders up on our site. We post the location of the site and include a link to the news site containing information about the testing kiosk.

The map is at We have also built an application programming interface that we are happy to share with anyone who can help get this data to the end-users. At a time when information about COVID-19 is either scarce, confusing, or simply unknown, our project goal is to provide the power of information directly to individuals so they can protect their health and the health of loved ones and neighbors, and subsequently slow down and contain the further spread of COVID-19.

Further down the road, testing will also enable us to confidently resume returning to work, school, and our communities.   

What do you see as the role of artificial intelligence and big data in tackling a global emergency such as COVID-19?

Because of COVID-19, the year 2020 has caused the health care technology industry to quickly shift in the direction of how other industries are leveraging AI to solve urgent pandemic-related problems. One example of how AI is being used now is the construction of better models that predict the global spread of the virus. Another example is building more precise geo-location risk identification systems, an effort being prominently spearheaded by Google and Apple, who announced a partnership to share mobile proximity data for contract tracing. Other companies are using non-traditional data sets, such as social media chatter, tweet locations, cell phone movement and migration, credit card purchases, and job-seeking activity by recently furloughed employees.

What’s more, feeding increasingly diverse data set information into powerful AI algorithms has the potential to create exponentially disruptive business solutions that will challenge the traditional “brick-and-mortar” hospital delivery mechanisms in place today. Can we imagine a better way to deliver health care solutions, similar to the remote testing sites unfolding across the country? Can we bring the health care providers closer to the patients and provide non-life- threatening services via a drive-through model? Maybe one day a Johns Hopkins Carey-trained entrepreneur will make health care services as convenient as getting tested for COVID-19 at a drive-through. The future of AI is here and only limited by one’s imagination and energies to produce a better tomorrow.

Experts haven’t changed their estimates for COVID-19 immunity duration, despite Trump's claim

We rate this claim as mostly false. Infectious disease experts did not shift from saying immunity was lifelong to saying it lasted only a few months for partisan reasons. Experts haven’t changed their estimates for immunity duration, which remains unknown. Most agree that it is not a "life-time".

CBD helps reduce lung damage from COVID by increasing levels of protective peptide
Medical College of Georgia at Augusta University

One way CBD appears to reduce the "cytokine storm" that damages the lungs and kills many patients with COVID-19 is by enabling an increase in levels of a natural peptide called apelin, which is known to reduce inflammation and whose levels are dramatically reduced in the face of this storm.
