SYRACUSE, N.Y. -- Officials have confirmed the first known case of the novel coronavirus in Onondaga County, according to County Executive Ryan McMahon.

The case was confirmed at 8:50 a.m. Monday. The patient is a woman in her 70s, McMahon said.

The woman has “significant underlying medical history,” according to Health Commissioner Dr. Indu Gupta. Gupta said the patient has been admitted to the hospital.

Gupta said the person does not have recent travel history outside the county.

“It’s here,” Gupta said of the coronavirus.

The county previously declared a state of emergency and recommended people practice social distancing in an effort to slow the spread of the virus.

McMahon said the county has spent the last week or more planning for a confirmed case in Onondaga County. He urged vigilance but also asked people to remain calm.

He said he will be issuing an executive order urging “common sense” and will institute a mandatory quarantine for anyone who has taken a coronavirus test. That means anyone who has been tested should stay in isolation pending the results of that test. Those results usually take about 24 to 48 hours, according to Dr. Gupta.

“We need to work together as a community,” he said.

The Syracuse Community Health Center opened a testing site Monday morning. McMahon said there are already 50 people signed up for testing.

All Onondaga County schools will be closed starting at 4 p.m. today.

The Marcellus School District canceled school today.

At 9:05 a.m., the district was notified of the confirmed case. It turned the buses around for students headed to K-6 classes. The students were returned home. Students in classes 7-12 were already in class. They will remain in class until dismissal at 2:20 p.m.

Superintendent Michelle Brantner said she had word from the county executive’s office of the confirmed case before elementary students were picked up, and she decided to send children home “just to not create exposure unnecessarily.”

The district said today that the confirmed coronavirus case was not related to the Marcellus bus driver who last week went into 14-day quarantine. The bus driver had voluntarily quarantined “because a family member recently returned from a country with a high infection rate,” the district said in a letter to parents March 11. The family member showed no symptoms, the letter said.

“The confirmed case is not in Marcellus nor is the person connected to Marcellus,” Brantner said.
