Virginia Gov. Ralph Northam and first lady Pamela Northam have both tested positive for COVID-19, the governor’s office announced Friday morning.

On Wednesday, the couple was told that a member of the governor’s residence staff who works in their living quarters had developed symptoms and tested positive for coronavirus. Both the governor and first lady received PCR nasal swab tests on Thursday afternoon and tested positive, according to a press release.

While Gov. Ralph Northam is currently not experiencing symptoms, Pamela Northam is experiencing mild symptoms. “Both remain in good spirits,” the release said, and the couple will self-isolate for 10 days, in accordance with Virginia Department of Health guidelines.

“As I’ve been reminding Virginians throughout this crisis, COVID-19 is very real and very contagious,” the Democratic governor said in a statement. “The safety and health of our staff and close contacts is of utmost importance to Pam and me, and we are working closely with the Department of Health to ensure that everyone is well taken care of. We are grateful for your thoughts and support, but the best thing you can do for us — and most importantly, for your fellow Virginians — is to take this seriously.”

Northam’s announcement came just after he visited George Mason University on Tuesday, where GMU’s President Gregory Washington spoke of his efforts to control the virus on campus. Washington said the university recently tested about 3,000 residential students and found only 12 cases.

“Governor, you being here today is probably safer than just about any place you could be in the commonwealth, with the exception of your home,” Washington said at the time.

Michael Sandler, a spokesperson for George Mason University, wrote DCist/WAMU in an email that Northam “was on campus for a short time on Tuesday, wore a mask during his entire visit and came into close contact with a very small group of individuals.”

Sandler added that the Virginia Department of Health will reach out to people who were in close contact with the governor, and urged people concerned about possible exposure to call their health care provider.

The Virginia first couple is working with VDH and Richmond’s Health Department to undergo contact tracing, as the executive mansion and Patrick Henry office building are closed down for deep cleaning.

“The work of the Governor’s office continues remotely and uninterrupted,” the release said.

Northam’s office did not immediately respond to a request for comment.

Statewide, daily reported COVID-19 cases have been on a slight downturn this week, with a seven-day average of 819 as of Friday, per VDH data. That’s compared to an average of 908 a month ago, and 1,034 in July.

Virginia’s positivity rate has been steadily declining, this week hitting the lowest level since it was first reported in March. On Tuesday, VDH reported the seven-day average was 5.1%, and as of Friday, data tracked by journalist Alejandro Alvarez shows the average at 4.1%.

Still, Virginia is reporting hundreds more cases per day than Maryland, a reversal of trends earlier in the pandemic. Deaths across the commonwealth have been harder to track, as data backlogs have led to inconsistent reporting. On Friday, VDH recorded a seven-day average of just under 27 COVID-related deaths reported per day.
