COVID-19 aerosol infection risk estimator

This tool has been developed to provide an estimate of the propagation of COVID-19 by aerosol transmission. This model does NOT include droplet or contact transmission. An inherent assumption is that personal hygiene measures and safe-distancing measures are being followed. If that is not the case, it is safe to assume that there will be more infections than predicted by the tool.

The current tool is based on the estimator created by Prof. J L Jimenez. The model used in the tool is based on the Wells-Riley model. The Wells-Riley model was calibrated further by Prof. Jimenez to COVID-19, based on results from recent literature regarding infectious quanta emitted by individuals.

This is NOT an epidemiological model. It does take input from epidemiological models for the estimated number of infected people in a community, during a specific time period. The model also focuses on the specific location being analysed and CANNOT be used to estimate risks of the people before they came to the place or after they leave.
