Here is a great online tool for visually estimating your #COVID19 risks. This interactive tool can show you the ways an infected person can infect others in different scenarios. Singing indoors (concerts, churches, etc.) is high risk (left), but if both people wear surgical masks, the risk is considerably less (right). #WearAMask!

A example of a BMJ tool (mentioned above) that allows users to select from drop down menus to COVID19 estimate transmission risks. Interventions are represented as lines that block/filter thicker coloured lines indicating transmission routes. Risk is indicated by the saturation of colour in thick lines. These particular screenshots have been adjusted for singing conditions (in a large room with ventilation off) with and without masks.
