The omicron variant served notice of COVID-19's ability to quickly evolve and outpace our ability to control it. But human capabilities are improving swiftly, too, as the battle against this new pathogen continues into its third year.
One scientific advance involves work at surprising locations: Minnesota wastewater treatment plants.
Data mined from sewage could help control the COVID-19 pandemic by detecting new variants and predicting future surges. It could help fight other pathogens in the same way. That's why the innovative teamwork behind this, led by the University of Minnesota Medical School, deserves a spotlight.
Yes, there is a yuck factor and along with it, an irresistible urge for writers to make puns about data dumps and downloads. But turning what we've flushed into a weapon against COVID and other infectious diseases is smart thinking.
It appears that poop could be a gold mine of information when it comes to COVID viral circulation. We all answer nature's call, and in doing so, shed viral RNA as well if infected. Scientists can measure concentrations of that genetic material in samples collected downstream, with the data providing an early warning about viral spread in the area served.
"We have shown repeatedly through each surge that measures of RNA in wastewater reliably predict up to two weeks in advance increases in cases and we've published that," said Dr. Tim Schacker, vice dean for research at the U's medical school. "There are data now that are being published from other centers, who have smaller catchment areas than we do, and they're reporting a similar thing.
"I think these methods are pretty sound."
