The future of virus tracking lives on campus
University, research center pioneer way to manage outbreaks
One weekend last August, Shynell Moore woke up with a headache and a sore throat. Moore, then just a few weeks into her junior year at Colorado Mesa University, pulled out her phone and fired up a symptom-tracking app called Scout.
Within seconds of reporting her symptoms, the screen turned red: She might have COVID-19, the app said. She promptly got a call from a school administrator, and before the day was out, she had packed some clothes and her elephant ear fish, Dumbo, and moved into quarantine housing. Her COVID-19 test soon came back positive.
Several days into her quarantine period, Moore took a whiff of Dumbo’s typically malodorous food. “I couldn’t smell it,” she said. “Then I drank some cough syrup, and I couldn’t taste it.” She opened Scout and clicked an option: “Lost taste or smell.”
Each time she reported a symptom, the information was transmitted to Lookout, the university’s digital COVID-19 dashboard. Over the months that followed, Lookout evolved into a sophisticated system for tracking COVID-19 symptoms and cases across campus, recording students’ contacts, mapping case clusters, untangling chains of viral transmission and monitoring the spread of new variants.
“Colorado Mesa has the most sophisticated system in the country to track outbreaks,” said Dr. Pardis Sabeti, a geneticist at the Broad Institute of MIT and Harvard who has helped health officials around the
world respond to Ebola, Lassa fever and other infectious diseases. “It’s definitely the kind of analytics that people talk about having but nobody actually has access to in this way.”
Lookout is the product of a partnership between CMU — a school that prides itself on serving disadvantaged students — and the Broad Institute, a genomic research center in Cambridge, Massachusetts.
Together, they have turned CMU’s campus of 10,000-plus students into a real-world, real-time epidemiological laboratory, experimenting with creative approaches to pandemic management.
In 2016 and 2017, mumps outbreaks blossomed across Massachusetts. Sabeti worked closely with state public health researchers, watching them map case clusters by hand and log data in increasingly unwieldy
Excel spreadsheets.
In the years that followed, Sabeti and her postdoctoral fellow Andres Colubri worked with a local firm, Fathom Information Design, to develop a symptom-tracking and contact-tracing app that could be used in future outbreaks.
They were still developing the app, which became Scout, when COVID-19 hit. “Five-year plans turned into six-month plans,” Sabeti said. Fathom raced to finish the app, while Sabeti looked for a place to pilot it.
She had begun advising colleges across the country on their coronavirus responses, but CMU, based in Grand Junction, Colorado, immediately stood out to her. “We were looking for somebody who was scrappy, hungry, ready to go,” Sabeti said. “And we felt there was a need there.”
Like many schools, CMU
had suspended its in-person classes in mid-March 2020. But CMU administrators worried that their students — two-thirds of whom were students of color, low-income or the first in their families to go to college — might be permanently derailed by a semester, or longer, spent entirely online.
And so the administration made a decision: In the fall, it would bring students back to campus. All of them. “It became really obvious very quickly, this was a moral imperative,” said John Marshall, the school’s vice president. “We had to find a way to get back.”
When students returned in August, Scout became their campus wellness passport. Every day, they used Scout to report whether they had any COVID-19 symptoms or had recently traveled outside the area. If they had no symptoms and no recent travel, the screen turned green. This green screen was their ticket to enter the classroom, the cafeteria and other campus buildings.
The data was fed into Lookout, the dashboard that Fathom had developed to give administrators a holistic view of what was happening on campus. In addition to aggregating symptom data, Lookout also pulls in hourly results from the university’s coronavirus testing site. The university created a tiered testing strategy. Taking inspiration from the school mascot, the Maverick, CMU asked students to sort themselves into family units, or “mavilies,” that encompassed their regular close contacts.
Lookout also displays a geographic heat map of cases, a dorm view with room-by-room maps of positive and negative test results, and data from a new wastewater surveillance system, which tracks the coronavirus levels in the sewage flowing from various dorms. (People with COVID-19 shed the virus in their stool.) “As Lookout came together, it took this really complicated web of data and helped us start to both visually see it and to start making sense of it,” Marshall said.
The wastewater data has proved critical. In late September, for instance, the team noticed a sudden spike in the viral levels in wastewater from Grand Mesa, a suite-style residence hall. They responded by strategically testing a subset of residents, making sure to get at least one from each suite or mavily. They found two positives, traced their contacts and sent the infected students into quarantine.
Over the longer term, Sabeti and her colleagues hope to build versions of Scout and Lookout that can be used by schools, companies, local governments and other organizations to respond to outbreaks of infectious disease.
CMU is also looking ahead, brainstorming about how they could adapt Scout for the fall, when many students will be vaccinated, and whether they can use their new tools to slow the spread of other infectious diseases, like the flu.
Marshall is pleased with how the past year has gone. Yes, they had COVID-19 cases, he said, but they also had 881 freshmen who were the first in their families to go to college — who were able to actually go to college.
“It was never about how do you stop a virus?” Marshall said. Instead, he said, the challenge was: “How do you manage life while dealing with a pandemic? And in that regard, I would say we’ve done as strong of a job as anybody.”
