Parasitic Resilience: The Next Phase of Public Health Preparedness Must Address Power Imbalances Between Communities.

Community resilience, a system's ability to maintain its essential functions despite disturbance, is a cornerstone of public health preparedness. However, as currently practiced, community resilience generally focuses on defined neighborhood characteristics to describe factors such as vulnerability or social capital. This ignores the way that residents of some neighborhoods (as "essential workers") were required during the COVID-19 pandemic to sacrifice their wellbeing for the sake of others staying at home in more affluent neighborhoods. Using the global care chain theory, we analyze the way that the resilience of affluent neighborhoods depends on siphoning off the labor of other, less affluent neighborhoods, creating what we call the parasitic nature of resilience. We argue that understanding this neighborhood interdependence-and accounting for its parasitic nature-should be prioritized by public health authorities to prevent unintentional harm in future pandemics. Otherwise, any public health emergency response that relies on this labor (as did the COVID-19 pandemic response) depends on exploitative practices that produce the very disparities the response is trying to address. We explore the theoretical grounding and practical effects of this idea to provide the preparedness enterprise with an initial set of theoretical tools to move from a model of community resilience to one of community renewal. The community renewal model is based on an underlying ethics of care, in which systems are redesigned to become more prosocial during a public health response. We believe this model can more successfully address the tragic inequities in labor and health outcomes that we see during public health emergencies.

Establishing a Foundation for Performance Measurement for Local Public Health Preparedness.

The development of performance measures is not a new concept in the disaster preparedness space. For over a decade, goals have been developed and tied to federal preparedness grant programs. However, these measures have been heavily criticized for their inability to truly measure preparedness. There is also growing frustration at the local level that these performance measures do not account for local readiness priorities or the outcome-driven value of emergency response activities. To define an appropriate theoretical framework for the development of performance measures, a review of the literature on existing planning and preparedness frameworks was conducted, with an iterative feedback process with a local health agency. This paper presents elements of that literature review that were most directly along with the conceptual framework that was used as a starting point for future iterations of a comprehensive performance measure development project.

The NYC Health Department's Reflections on First-Ever Public Health Deployments in Support of Puerto Rico and the US Virgin Islands After the 2017 Hurricane Season.

In late 2017 and early 2018, the New York City Department of Health and Mental Hygiene deployed multiple teams to Puerto Rico and the US Virgin Islands to support public health in those territories. This article is a description of how those teams were conceived, deployed, supported, and reintegrated into the agency. This was an unprecedented mission for our agency, and what follows is a reflection on what worked and what didn't work for us. It is our hope that other jurisdictions can use this information to organize and execute similar missions in the future, and that collectively we can continue to advance the field of public health preparedness and response.

A Large Community Outbreak of Legionnaires' Disease Associated With a Cooling Tower in New York City, 2015.

OBJECTIVES: Infections caused by Legionella are the leading cause of waterborne disease outbreaks in the United States. We investigated a large outbreak of Legionnaires' disease in New York City in summer 2015 to characterize patients, risk factors for mortality, and environmental exposures. METHODS: We defined cases as patients with pneumonia and laboratory evidence of Legionella infection from July 2 through August 3, 2015, and with a history of residing in or visiting 1 of several South Bronx neighborhoods of New York City. We describe the epidemiologic, environmental, and laboratory investigation that identified the source of the outbreak. RESULTS: We identified 138 patients with outbreak-related Legionnaires' disease, 16 of whom died. The median age of patients was 55. A total of 107 patients had a chronic health condition, including 43 with diabetes, 40 with alcoholism, and 24 with HIV infection. We tested 55 cooling towers for Legionella, and 2 had a strain indistinguishable by pulsed-field gel electrophoresis from 26 patient isolates. Whole-genome sequencing and epidemiologic evidence implicated 1 cooling tower as the source of the outbreak. CONCLUSIONS: A large outbreak of Legionnaires' disease caused by a cooling tower occurred in a medically vulnerable community. The outbreak prompted enactment of a new city law on the operation and maintenance of cooling towers. Ongoing surveillance and evaluation of cooling tower process controls will determine if the new law reduces the incidence of Legionnaires' disease in New York City.
