A modelling framework to assess the likely effectiveness of facemasks in combination with ‘lock-down’ in managing the COVID-19 pandemic

COVID-19 is characterized by an infectious presymptomatic period, when newly infected individuals can unwittingly infect others. We are interested
in what benefits facemasks could offer as a nonpharmaceutical intervention, especially in the settings where high-technology interventions, such as contact tracing using mobile apps or rapid case detection via molecular tests, are not sustainable. Here, we report the results of two mathematical models and show that facemask use by the public could make
a major contribution to reducing the impact of the COVID-19 pandemic.
