U of I reports results weekly of tests processed through testing protocols for Moscow-based university-wide testing. This is not necessarily inclusive of all positive cases in people associated with U of I. The numbers below are a snapshot for the time period described and are reported using the Idaho Public Health guidelines, though numbers here may not match the official reporting of Idaho Public Health. In an effort to produce timely reporting, numbers reported here may include some people who were known to previously be positive, have already completed their required quarantine period and are no longer infectious. These people are not included in the public health reporting.

Idaho Public Health reporting is available on their website.

The U of I statistics below:

• Include both U of I employees and students;
• Do not reflect the number of swabs collected;
• Do not represent total number of unique individuals who have been tested;

Percent of Positives to Total: 3.76%

This week included random surveillance testing of our asymptomatic population, increased symptomatic testing and increased close contact testing after the six day minimum wait period from last exposure. Next week will not include the random general surveillance testing, so we do expect an increase in the percent of positives as symptomatic testing will be a larger percentage of the overall tests conducted.

The university currently has 2.54% of positives in total results received since the start of testing in early August.

This week the university initiated a re-test of all Moscow based students attending in person classes. There were positives in students living on and off campus. The highest concentration of positives were in the on campus Greek live-in population; however, there was a significant improvement over the past two weeks.

There is little to no infection across the off campus students and employees.

Targeted surveillance testing of close contacts to known clusters of positives was completed this week. Positives were primarily found in live-in members of Greek chapters. In addition to the targeted surveillance testing, we will conduct a large random surveillance testing next week with a broader cross-section of our population, including employees, to better understand the positive rate of the overall U of I community.

Sept. 12 to Sept. 18 – Posted on Sept. 21

Total Tests Received: 531

The University of Idaho implemented PCR COVID-19 testing through its own lab beginning in Aug. 2020. This data only reflect tests done through the U of I testing contract.

This is a weekly reflection of COVID-19 activity on the University of Idaho Moscow campus. Testing strategies each week were based on data and modeling so one week cannot necessarily be compared to another as a direct reflection of increase or decrease of the virus. Testing strategies included:

• Testing of all students attending in person classes in a set time period (ie: upon return to campus after a break)
• Testing of student-athletes (done on regular intervals)
• Targeted testing of students in areas of increased cases
• Random surveillance testing of faculty, staff and students, focused on finding asymptomatic cases
• Individual-requested testing (after travel, possible exposure, symptomatic and other appropriate reasons)

Some or all of these tactics were implemented on any given week.

Fall 2020 2.72% of 23,559 test results received were positive.
