Just 18 Penn State students tested positive for COVID-19 through on-arrival testing this fall, according to the university.

Last week, preliminary testing data indicated a positivity rate of students that was less than half a percent. Final data placed the positivity rate at 0.7%.

Of the approximately 14,000 students who moved into on-campus residence halls last week, 2,639 students were required to take a COVID-19 test before moving in. All students who hadn’t submitted proof of vaccination to the university were required to get tested.

Those who tested positive were either required to enter on-campus isolation for 10 days or return home for the same amount of time. All students who tested positive were also required to take a secondary PCR test to confirm the positive test result.

All students who have not provided proof of vaccination, regardless of whether they live on campus or off campus, will be required to get tested on a weekly basis this fall.

In its release, Penn State said approximately 83% of students living on campus have submitted proof of vaccination.
