New York Cityβs health department served notice of the second death in a statement on Saturday. The statement didnβt have any information about that personβs identity, age, or details on when and how they fell ill, as was the case when city officials on Friday announced the first death in the outbreak on Manhattanβs Upper East Side. It also didnβt specify the exact source of the outbreak, which as of Saturday had sickened at least 72 people, including nine people who remained hospitalized and 50 who had been discharged from the hospital. Nonetheless, a statement attributed to the New York City health commissioner, Dr Alister F Martin, said there was βencouragingβ data suggesting that βan aggressive strategy of testing, enforcement and remediationβ aimed at air-conditioning systems atop many large buildings βappears to have stopped the source of exposureβ.

City officials took those measures after two people on 2 July were confirmed to have been infected with legionnairesβ disease, which is a form of pneumonia. The agency confirmed an average of more than eight new cases daily through 8 July. The number of new cases then dropped to fewer than one daily from 10 to 17 July. βWe will continue inspecting every cooling tower that tested positive and will hold accountable any owner who fails to comply with our public health laws,β Martinβs statement said. According to the city, tests identified either living or dead Legionella bacteria in cooling towers on more than 75 Upper East Side buildings. They include museums , private schools and apartment houses. The statement also expressed
