ST. LOUIS COUNTY, MO (November 23, 2020) – At least one out of every 100 St. Louis County adult residents had an active COVID-19 infection earlier this fall, while about five out of every 100 adults had contracted the disease at some earlier point, according to test results of a representative sample of county residents.
Results of the testing, commissioned by St. Louis County Department of Public Health and launched by the Institute of Public Health at Washington University in St. Louis as he COVID-19 St. Louis County Survey, raised fresh concerns from experts about the high risk of further, rapid spread of the disease in the county – especially given the explosion in COVID-19 cases since the testing was conducted.
