This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
BackgroundEarly in the SARS-CoV-2 pandemic, many national public health authorities implemented non-pharmaceutical interventions to mitigate disease outbreaks. Panama established mandatory mask use two months after its first documented case. Initial compliance was high, but diverse masks were used in public areas. We studied behavioral dynamics of mask use through the first two COVID waves in Panama, to improve implementation of effective, low-cost public health containment measures, when populations are exposed to novel air-borne pathogens. MethodsMask use behavior was recorded from pedestrians in four Panamanian populations (August to December 2020). We recorded facial coverings; and if used, the type of mask, and gender and estimated age of the wearer. FindingsPeople were highly compliant (> 95%) with mask mandates, and demonstrated important population-level behaviours 1) decreasing use of cloth masks over time, and increasing use of surgical masks; 2) mask use was 3-fold lower in sub-urban neighborhoods than other public areas; and 3) young people were least likely to wear masks. InterpretationResults help focus highly-effective, low-cost, public health interventions for managing and controlling a pandemic. Considerations of behavioural preferences for different masks, relative to pricing and availability, are essential for optimizing public health policies. Policies to increase availability of effective masks, and behavioral nudges to increase acceptance, and to facilitate mask usage, during the on-going SARS-CoV-2 pandemic, and for future pandemics of respiratory pathogens, are key tools, especially for nations lagging in access to expensive vaccines and pharmacological approaches.
