Spatio-Temporal Cluster Detection for Legionellosis using Multiple Patient Addresses

The Bureau of Communicable Disease (BCD) at the NYC Department of Health and Mental Hygiene performs daily automated analyses using SaTScan to detect spatio-temporal clusters for 37 reportable diseases. Initially, we analyzed one address per patient, prioritizing home address if available. On September 25, 2015, a BCD investigator noticed two legionellosis cases with similar work addresses. A third case was identified in a nearby residential facility, and an investigation was initiated to identify a common exposure source.

Detecting and Investigating a Large Community Outbreak of Legionellosis — South Bronx, July 2015

We will present an overview of: (1) the epidemiology of Legionnaires’ disease (LD), (2) techniques applied by the New York City (NYC) Department of Health and Mental Hygiene for routine LD surveillance and outbreak investigation, (3) detection and investigation of the second largest community-acquired LD outbreak in the U.S (South Bronx, July 2015), and (4) recent legislation enforcing regular maintenance, testing, and mediation of NYC cooling towers.

Place Matters: Revealing Infectious Disease Disparities Using Area-Based Poverty

Most public health surveillance systems in the United States do not capture individual-level measures of socioeconomic position. Without this information, socioeconomic disparities in health outcomes can be hidden. However, US Census data can be used to describe neighborhood-level socioeconomic conditions like poverty and crowding. Place matters. Neighborhood affects health independently of personal characteristics.

Prospective Spatio-Temporal and Temporal Cluster Detection by Salmonella Serotype

Nontyphoidal Salmonella, consisting of >2,500 distinct serotypes, is the leading bacterial agent of foodborne illness in the U.S., causing an estimated 1 million infections per year. In NYC, interviews of all case-patients (N≈1,100 annually) are attempted to support outbreak investigation and control. Salmonella clusters in NYC are typically identified either by notification from PulseNet, CDC, or other health departments or by a weekly analysis using the historical limits method.
