Some county data reflects what was seen in September, when the dial was previously in the moderate stage, but Jones said other trends in the last week pointed to a potential uptick in cases. Olmsted County saw the number of newly confirmed cases rise to 105 during the weekdays last week, compared to 74 a week earlier. Additionally, he said ongoing efforts to track COVID-19 through the city’s wastewater saw numbers decline on March 5, only to jump on March 12. Rochester Public Works Director Wendy Turri said the testing, which started last year, can indicate likely future increases or decreases in COVID-19 cases, based on tracking the ribonucleic acid, commonly known as RNA, found in the coronavirus that ends up in wastewater.
