A Legionnaires' disease outbreak in New York City's Harlem neighborhood has claimed one life and sickened at least 22 others since late July. Health officials urge residents with flu-like symptoms, particularly those over 50, smokers, or with lung conditions, to seek immediate medical attention. The disease, a type of pneumonia caused by bacteria thriving in warm water, is treatable with antibiotics. Investigations are underway to identify the source, with cooling towers in the area being tested and remediated.
