Legionnaires' has popped up in a Bronx complex. Officials say it differs from the Harlem cases.
A Bronx apartment complex is under evaluation for Legionella after multiple residents tested positive for Legionnaires' disease, prompting building-level water-system assessments.
Legionella bacteria lurk quietly in the water systems of many New York City buildings, posing a persistent yet largely hidden health threat. Just this week, local health officials announced a cluster of such cases in Harlem.
