Each week, more than 500 people make their way to Weyerhaeuser Hall on the Macalester College campus in St. Paul, where they swab the insides of their lower nostrils under medical supervision to get tested for COVID-19.
The students and employees, selected semi-randomly by a computer to provide nasal samples for COVID testing, have no symptoms of the disease and no reason to suspect they re infected.
And that s the point.
When COVID-19 case counts fall, doctors and public health officials say the importance of finding and isolating asymptomatic carriers will re-emerge as a top priority for ending the pandemic. An analysis published last month in JAMA Network Open estimated more than half of all COVID-19 transmission originates in people who don t know they are infected.
Scientists look to Twin Cities sewers to find COVID variants The hunt for new strains locally is piggybacking on long-running COVID wastewater surveillance. February 15, 2021 5:34am Text size Copy shortlink:
Some of the best evidence for detecting early signs of new COVID strains in Minnesota is being flushed right down the toilet.
But scientists at the Metropolitan Council and the University of Minnesota s Genomics Center have started work to detect new strains of COVID in the wastewater flowing into the Twin Cities primary sewage treatment plant in St. Paul.
The project is an outgrowth of ongoing epidemiological work with Minnesota s wastewater. Genetic traces of the virus that causes COVID are detectable in wastewater, which is why researchers are analyzing it for early warnings about COVID hot spots.
