Since Sunday, 13 cases of the coronavirus have been confirmed in New York, and residents have adopted a variety of strategies to curb the spread of the illness.

[Two new cases of coronavirus were confirmed in New York City.]

Here’s how the outbreak, and the reaction to it, has unfolded in New York:

The first case, on Sunday: A health care worker

State officials announced on Sunday that a Manhattan woman, 39, had contracted the coronavirus. The woman, a health care worker, had returned to New York after visiting Iran, a hot spot for the outbreak.

The woman, who did not take public transportation home from the airport, has been in isolation with her husband — who has tested negative for the virus — since returning. On Wednesday, Governor Cuomo said she was recovering.

The second case, on Tuesday: A lawyer

Before the state had confirmed the first case, another case was developing: A man from New Rochelle, just north of New York City, became ill on Feb. 22. A neighbor drove him to a hospital in Westchester County on Feb. 27.
