Judy Persichilli will be voluntarily quarantining in her home until Dec. 8 "out of an abundance of caution and in line with the Department’s guidance," a statement from a DOH spokesperson said.
The news comes after a member of Persichilli's office tested positive for COVID-19, officials said.
The employee was last in the building on Nov. 24, and is isolating at home.
According to the CDC, 71-year-old Persichilli is at higher risk of severe effects from the virus. She will not be participating in in-person press briefings while isolating.
On Saturday, an additional 3,924 COVID-19 cases were reported in New Jersey, along with 24 deaths.
