The estimate implies an average reduction of 290%, compared to the proportion of the mandate-unaffected individuals who display all symptoms (0.1%).Conclusion: The study provides suggestive evidence for the health benefits of wearing masks in public in the initial stage of the COVID-19 pandemic. The study also highlights the relevance of public mask wearing for the ongoing pandemic where the vaccination rate is precarious and access to vaccines is still limited in many countries.Keywords: COVID-19, coronavirus symptoms, mask mandates, face masks
