ABSTRACT
This report describes the rapid implementation of a statewide observational surveillance program to monitor the public's wearing of face masks in public spaces during community spread of Coronavirus disease 2019 (COVID-19). It describes how the Hawai'i State Department of Health partnered with University of Hawai'i faculty to develop and implement the surveillance program. The surveillance program involved organizing volunteers to conduct weekly direct observations in designated locations. A smartphone application (app) was created to record real-time observational surveillance data. From September 5, 2020, to March 13, 2021, a total of 84 577 observations were conducted across the state. Eighty-three percent of those observed were correctly wearing a face mask, 7% were wearing a face mask incorrectly, and 10% were not wearing a mask. Following the 2-week pilot phase of the project, volunteers were surveyed regarding facilitators and barriers for conducting observations and motivations for volunteering. Feedback was used to refine project procedures. With few states having implemented such a surveillance program, the information reported in this article may inform communities interested in tracking mask-wearing behaviors in the context of the COVID-19 pandemic.
