• [Pre-print, not peer-reviewed] An analysis of saliva specimens collected through a campus-wide surveillance program for SARS-CoV-2 among students at the University of Colorado, Boulder during the Fall academic semester of 2020 found that 2% (1,405 of 72,500 specimens tested) of the samples were positive for SARS-CoV-2. All of the positive students self-reported no symptoms on the day of collection. Residents of dormitories were tested weekly (August 27–December 11, 2020), and several campus testing sites offered testing for any campus affiliate. Viral load levels in the asymptomatic students had similar distributions compared to hospitalized symptomatic individuals from reference studies.
