A 39-year-old woman took Flight 701 from Doha, Qatar, to John F. Kennedy International Airport in late February, the final leg of her trip home to New York City from Iran.
A week later, on March 1, she tested positive for the coronavirus, the first confirmed case in New York City of an outbreak that had already devastated China and parts of Europe. The next day, Gov.
