Yesterday the first confirmed case of coronavirus (COVID-19) was reported in the nation's largest city:

A 39-year-old Manhattan woman has tested positive for COVID-19, more commonly known as the novel coronavirus, Gov. Andrew Cuomo said late Sunday. She is the first confirmed case in the city and in the tri-state area.

"The patient, a woman in her late thirties, contracted the virus while traveling abroad in Iran, and is currently isolated in her home," Cuomo said in making the announcement late Sunday.

The governor said that the woman is a health care worker, and that her background allowed her to take the appropriate precautions and seek testing. She flew back to New York on Tuesday but did not take mass transit home, Cuomo said Monday. As a precaution, the people on her flight and the ride-share driver are being notified about potential exposure, but Cuomo said the woman was not thought to be contagious at that time. She has respiratory symptoms but Cuomo described them as mild.
