SAN FRANCISCO, Calif. (KRON) – The San Francisco Symphony had to cancel its performance on Thursday afternoon after positive COVID cases were reported within the orchestra.

The symphony was set to perform at 2 p.m. in the Davies Symphony Hall.

In a statement posted to Twitter, the symphony said:

“Despite robust safety measures in place, positive COVID-19 tests were reported within the Orchestra during routine testing earlier this afternoon.
