Positive, cumulative cases of COVID-19 at the University of Colorado Boulder have spiked dramatically since the start of the fall semester, prompting the chancellor to issue a letter urging students to do their part.

“We need to stop the recent rise in positive COVID-19 cases immediately by wearing face coverings, avoiding gatherings of more than 10 people, practicing physical distancing and staying home when experiencing any COVID-19 symptoms,” the letter says.

The number of positive diagnostic tests through CU Boulder Medical Services stands at 308 to date, jumping from 13 in week one, to 90 in Week 2 and up to 205 in Week 3. The cumulative data so far runs from Aug. 24 to Sept. 13, the letter says.

Of the 308 positive cases confirmed so far, 29% are among on-campus residents and 71% are among individuals living off campus.

“As the majority of our cases are off campus, we are collaborating closely with our partners in the city, county and state to discuss options. We expect we will soon deploy new testing strategies and additional measures in an effort to change the behaviors contributing to the increase,” Chancellor Phil DiStefano wrote in the letter.
