Positive samples led to an entire dorm being tested for COVID-19. “Poop can tell you the truth about yourself and your community.”
The University of Arizona discovered two students had the coronavirus with no symptoms and were able to stop an outbreak in its tracks because of wastewater testing.
Dr. Ian Pepper, an environmental science professor at the university and the director of its Water & Energy Sustainable Technology Center, told the outlet that his team has been sampling sewage from dorms, as it “can pick up a single positive case in a group of 10,000.” “By analyzing the sewage, we’re actually monitoring the whole community with one test,” he said, adding that wastewater testing can give “the total virus load shed by infected individuals both with symptoms and asymptomatic ― no symptoms.”
“That gives you seven precious days in which you can put in mitigation or interventions to try to deal with the virus. I think about a week in the U.S. is probably equivalent to 20 or 30,000 cases,” he told the podcast.
