In a press release Thursday, the City of Oak Ridge said it is alarmed by the 12.5 percent positivity rate for COVID-19 in the Oak Ridge area, and wastewater testing shows the disease is present across the city.

The positivity rate measures the percentage of tests that return positive results out of the new tests each day. A 12.5 percent positivity rate means that 12.5 tests are positive out of each 100 new tests, on average.

A 12.5 percent positivity rate is high. World Health Organization guidelines call for a positivity rate below 5 percent for 14 days before activities re-open.

In its press release, the city said the 12.5 percent positivity rate in the Oak Ridge area was measured earlier this week and was obtained from zip-code specific data from the Tennessee Department of Health.

Three more COVID-19 cases were reported among Oak Ridge Schools students on Wednesday and Thursday. Two were at Oak Ridge High School, and one was at Woodland Elementary School. There have 13 cases among students since Friday and eight cases among ORHS students in the past week.

The surge in cases among students has occurred as middle schools prepare to return to in-person classes five days per week starting Monday. Student cases were reported almost every day this past week, with the number of cases ranging between one and four. That is a higher number of cases per day than at any other time this school year.

Oak Ridge Schools Superintendent Bruce Borchers has said about 80 percent of COVID-19 cases in the schools have been due to activities outside of school. On Wednesday, he said 85.2 percent of the student cases in Oak Ridge Schools have been confirmed to be non-school related.

Borchers said the schools are not aware of any cases in which students or staff members have developed COVID-19 because they were in close contact with a person at school who was confirmed to be COVID-positive. Also on Wednesday, the Vanderbilt University Medical Center Department of Health Policy in Nashville said major clusters of COVID-19 have not been traced to school transmission.

The largest number of COVID-19 cases in Anderson County is among young patients, with the 11-20 age group now reporting the most cases of any age group. (Graph by Oak Ridge Today using information from Tennessee Department of Health)

The largest number of COVID-19 cases in Anderson County is among young patients, with the 11-20 and 21-30 age groups now reporting the most cases of any age groups.

For more than a week, the case count among the 11-20 age group has been higher than the case count among the 21-30 age group.

That’s a change since earlier in the pandemic, when the 21-30 age group usually had the most cases of any age group, followed by several older age groups. It’s not clear what accounts for the change.

The 21-30 age group still has a high number of cases, and that age group still has close to the same number of cases as the 11-20 age group, according to information published by the Tennessee Department of Health. And on some recent days at least in the past month, the total number of cases among the 21-30 age group has been higher than the number among the 11-20 age group.

The two groups together now account for about one-third of COVID-19 cases in Anderson County.
