Data Resource Profile: Egress Behavior from Select NYC COVID-19 Exposed Health Facilities March-May 2020.

Vector control strategies are central to the mitigation and containment of COVID-19 and have come in the form of municipal ordinances that restrict the operational status of public and private spaces and associated services. Yet, little is known about specific population responses in terms of risk behaviors. To help understand the impact of those vector control variable strategies, a multi-week, multi-site observational study was undertaken outside of 19 New York City medical facilities during the peak of the city's initial COVID-19 wave (03/22/20-05/19/20). The aim was to capture perishable data of the touch, destination choice, and PPE usage behavior of individuals egressing hospitals and urgent care centers. A major goal was to establish an empirical basis for future research on the way people interact with three-dimensional vector environments. Anonymized data were collected via smart phones. Each data record includes the time, data, and location of an individual leaving a healthcare facility, their routing, interactions with the build environment, other individuals, and themselves. Most records also note their PPE usage, destination, intermediary stops, and transportation choices. The records were linked with 61 socio-economic factors by the facility zip code and 7 contemporaneous weather factors and the merged in a unified shapefile in an ARCGIS system. This paper describes the project team and protocols used to produce over 5,100 publicly accessible observational records and an affiliated codebook that can be used to study linkages between individual behaviors and on-the-ground conditions.
