Legionnaires’ outbreak rocks New York as experts warn of rising climate threat
The Guardian • • general
Key Points:
- An outbreak of legionnaires’ disease on Manhattan’s Upper East Side has sickened at least 28 people, prompting New York City health officials to test water from nearly 160 building cooling towers to identify the source.
- Health Commissioner Dr. Alister Martin linked the outbreak to climate change, describing New York as a “subtropical climate” that increases the risk of legionnaires’ clusters, and ordered at least 19 buildings to clean and disinfect their cooling towers.
- Legionnaires’ disease, caused by the bacterium Legionella pneumophila, is a severe pneumonia with a high fatality rate, and while rare, outbreaks have been rising globally due to aging infrastructure and environmental factors.
- The disease disproportionately affects marginalized communities, particularly Black Americans and residents in poorer neighborhoods, despite the current outbreak occurring in affluent areas.
- Identifying the exact source of the outbreak is complex and may take a month or more, as it requires culturing bacteria and genetic sequencing, with climate change expected to continue creating favorable conditions for Legionella proliferation.
