Public Health Messages About Face Masks Early in the COVID-19 Pandemic: Perceptions of and Impacts on Canadians.

Early in the COVID-19 pandemic, Canadians faced much ambiguity in the public health messages around face mask use. As public health messaging plays a pivotal role in the provision of directives during a health crisis, this study examines Canadians' opinions on the early messaging they received regarding personal protection, especially around mask use, with the goal of identifying potential improvements to strengthen future health messaging. Nine online focus group interviews with 47 Canadians were conducted. These natural conversations focused on personal protective equipment (PPE) choices, mask-relevant public health information sources, and advice to Canadian authorities to improve public health messaging on mask use. Responses were imported into NVivo for thematic analysis. Four meta-themes of relevance were identified. Despite demonstrating trust in scientific evidence and public health authorities, the inconsistencies in public health messaging fostered confusion, and induced mistrust toward health professionals. Further, several information deficits were identified pertaining to the scientific efficacy, safe use, and disposal of masks. Rooted in loyalty to healthcare workers, these Canadians eschewed using medical grade masks during PPE shortages to ensure a sufficient supply for medical workers. The findings stress that consistency in public health messages should be prioritized, with necessary changes clearly justified and explained. More information should reach the public on the scientific benefits and proper use of masks. Public health recommendations should be evidence-based, simple, transparent, and realistic in the current circumstances to guide Canadians to make more informed personal protection choices in the rapidly evolving pandemic.
