As of Tuesday, there were 15,597 confirmed coronavirus cases in New York City, with 192 deaths connected to the disease.

While the authorities warn that there will be many more fatalities from the virus, Ms. Romain’s struck a chord — the early death of a prominent New Yorker who has touched many people’s lives.

Ronda Phillips, 48, the principal at Kappa V High School, which uses the same building as the academy, is also hospitalized, school officials said.

Ms. Romain’s death drove home what the authorities have been warning all along, that the virus does not just kill the old and medically frail. As of now, only five people under the age of 45 in New York City have died from the virus.

“She was a healthy, vibrant, energetic 36-year-old woman who had one of the toughest jobs anybody could have, and she did it with resilience,” Ms. Winkfield said.
