A simple mathematical model for estimating the risk of airborne transmission of a respiratory infection such as COVID-19  is presented. The model attempts to incorporate the known scope of physical factors involved in the airborne transmission of such diseases , and is designed to serve not only as a common basis for scientific inquiry across disciplinary boundaries, but to also be understandable by a broad audience outside science and academia  .
A simple mathematical model for estimating the risk of airborne transmission of a respiratory infection such as COVID-19 , is presented. The model employs basic concepts from fluid dynamics and incorporates the known scope of factors involved in the airborne transmission of such diseases . Simplicity in the mathematical form of the model is by design, so that it can serve not only as a common basis for scientific inquiry across disciplinary boundaries, but , also be understandable by a broad audience outside science and academia . The model is used to assess the protection from transmission afforded by face coverings made from a variety of fabrics. In addition, the reduction in transmission associated with physical distancing between the host and susceptible as well as the level of physical activity of the host and/or the susceptible in enhancing transmission risk, is also examined .
