New York City officials said that water systems were safe for drinking and showering after an outbreak of Legionnaires’ disease.

The New York City Health Department put the total number of infected at 14 on Sunday, and it expanded the area of infection. The disease isn’t spread through person-to-person contact but rather the inhalation of contaminated water aerosols. New York City Mayor Zohran Mamdani said Sunday that home water systems are safe to use.
