Legionnaires' has popped up in a Bronx complex. Officials say it differs from the Harlem cases.

"The Bronx cluster - which includes four people in two buildings, diagnosed over several months - isn't linked to the Central Harlem Legionnaires' outbreak that has sickened more than 100 people this summer and killed six, according to city health officials. And officials say it's unlikely to turn into a similar public health event, since building clusters, often linked to a building's plumbing, are considered more contained."

"Gomez said the Bronx cluster is concentrated in two residential properties. The city health department began an evaluation of Parkchester South Condominium in the Bronx last week after two residents tested positive for Legionnaires' within two months of each other. The city initiated a similar building evaluation at Parkchester North in June in response to two cases within a 10-month period, Gomez said."

Multiple residents in a Bronx apartment complex tested positive for Legionnaires' disease, prompting evaluation of the building plumbing for Legionella. The Bronx cluster includes four people across two buildings diagnosed over several months and is not linked to the Central Harlem outbreak that sickened more than 100 people and killed six. The Central Harlem outbreak has been tied to contaminated water-cooling towers that can emit Legionella-laden mist over a broader area. City testing detected Legionella in 12 cooling towers at 10 Harlem sites that were ordered cleaned. Two Parkchester buildings in the Bronx are undergoing building-level water-system evaluations after clusters of cases.
