Cases of the virus have been on the rise in New Jersey, particularly the delta variant. State health officials reported 1,249 new positive PCR tests on Friday.

There have also been seven new confirmed deaths. Officials say that all of the deaths were people who did not have the COVID-19 vaccine.

The surge in cases prompted Gov. Phil Murphy to announce that all K-12 students, faculty and staff will be required to wear masks when school resumes in September.
