New York City health officials say water vapor spread through the air from a building's cooling tower likely caused the deadly Legionnaires outbreak in the Lenox Hill area on the east side of Manhattan.
At least one person has died and at least six others have been infected by the outbreak, which took place in the past two weeks.
Officials held an information session on Monday in response to the outbreak and City Health Commissioner Dr. Mary Bassett fielded questions from about 100 neighborhood residents, CBS New York reports.
"It's not spread by one person coughing, and another person getting it. It spreads through water mist," she said. Inhaling mist contaminated with Legionella bacteria can cause the illness, a severe form of pneumonia that mostly affects older people and those with weakened immune systems.
