There were 76 new positive coronavirus tests reported at Duke between Jan. 11 and Jan. 17, out of 21,542 total tests, according to data released Tuesday on the University’s COVID-19 testing tracker.
The 76 positive tests are the most that Duke has reported in a single week, eclipsing the 62 from the week of Jan. 3 to Jan. 10, although the number of tests conducted more than doubled between the two weeks.
Among students, there were 49 positive coronavirus tests out of 18,465 total, for a positivity rate of 0.27%. That includes 15 positives among students who participated in surveillance testing, out of 13,779 total.
Additionally, 12 of 318 tests were positive among students who had symptoms or were determined to have been in close contact with someone who tested positive, and 22 of 4,368 entry tests for returning students came back positive.
There were also 27 new positive tests among faculty and staff out of 3,077 total, for a positivity rate of 0.88%. That number includes four positive surveillance tests out of 2,887 total, and 23 positives out of 190 tests conducted on faculty and staff who had symptoms or were determined to have been in close contact with someone who had a positive COVID-19 test.
This week saw a higher number of positive cases among students compared to last week, but a lower positivity rate due to the larger number of tests conducted. The positivity rate for faculty also declined between this week and last week.
There are currently 90 active coronavirus cases on campus—55 among students and 35 among faculty and staff.
In total, 166 people were placed in precautionary quarantine and 75 were released last week, according to Monday’s update. A total of 76 people were placed in isolation and 47 were cleared to leave.
Since Jan. 3, Duke has administered 31,829 tests and reported a total of 138 positives among faculty, staff and students. Those 138 positive tests follow 241 from the summer and fall semester.
The University has conducted multiple kinds of testing, including entry testing of every returning student, testing based on contact tracing and pooled surveillance testing of asymptomatic people.
