Engineering students help track pandemic in Ohio
UC’s surveillance program has helped to keep COVID-19 in check on campus, professor says
The COVID-19 pandemic has had a staggering toll — nearly 7 million people dead, including more than 1.1 million in the United States alone.
Nationwide, health officials have documented 103 million cases of COVID-19 since the pandemic began in early 2020. And many survivors are still grappling with health issues related to their infection, known as long COVID-19.
As bad as that was, it could have been worse, University of Cincinnati Associate Professor David Wendell says.
For the past three years, he and his environmental engineering students have been participating in Ohio’s COVID-19 surveillance system, testing wastewater on campus to identify infections among students living in UC’s dorms and taking steps to prevent spikes in cases from spreading across campus.
Wendell said an early bout with COVID-19 in 2020 before vaccines were available made him appreciate how debilitating the disease can be.
“I had a really bad case,” he said. “I felt that if I could prevent one student from going home and infecting their parents, it would all be worth it.”
Wendell’s lab in UC’s College of Engineering and Applied Science invested in the equipment needed to amplify DNA, one of the steps epidemiologists use to identify new strains of the disease. He volunteered to work with Ohio’s Department of Health to monitor cases on campus through grants from the Centers for Disease Control and Prevention.
“At the time, people were scared,” he said. “We started the surveillance right when the pandemic began.”
You know they have COVID before they do.

Several times a week, students fan out across campus in latex gloves, clean room garb and eye protection to collect wastewater samples. Special pumps beneath manhole covers collect small samples of wastewater at regular intervals during the day to capture longitudinal data about the population on campus, particularly those living in the dorms.
“One of the biggest advantages of wastewater surveillance is to pick up the virus in the population before people are even symptomatic,” said Wendell, who holds a joint appointment in UC’s departments of biomedical engineering and chemical and environmental engineering.
“So you know they have COVID before they do,” he said.
During the pandemic, UC’s surveillance program on at least one occasion helped health officials such as Dr. Dustin Calhoun, the lead medical contact for the program, intervene early to prevent an observed increase in cases in one dorm from spreading across campus, Wendell said.
The program is sponsored by the Ohio Department of Health.
“We were able to identify a cluster of students who quarantined right before summer break last year to keep other people from getting sick. I think it made a difference,” Wendell said.
So far this fall, environmental engineering students are finding very little COVID-19 activity on campus in their lab tests.
“This year we’ve mostly only seen trace detection levels,” he said.
The surveillance program will continue through at least June.
UC student Nathan Deuitch said the public health project is what made him want to study environmental engineering.
“I find it quite exciting that I can work on a project like this as an undergraduate,” Deuitch said. “I wasn’t really expecting to be able to do much of anything in a lab as a first or second year, so doing a project of this magnitude is really neat to me.”

On April 15, 2021, over 100 faculty and staff across the University of Cincinnati graduated to become official Mental Health Champions, a now Healthy UC initiative. These dedicated colleagues successfully completed three trainings focused on creating connections and community, supporting students and co-workers with resources, and investing in their own personal wellness. Trainings were hosted by fellow colleagues who became facilitators in Question, Persuade, Refer (QPR), Counseling and Psychological Services (CAPS), and the Be Well UC employee wellness program. All Mental Health Champions actively demonstrate their commitment to building the culture of positive well-being at the University.
