More evidence that Covid is airborne and ventilation is key to limiting the spread of the virus. This report focuses on work done by physicist Lidia Morawska and Professor Trish Greenhalgh.
Now, we know the virus is in fact airborne. We know some people generate more particles in their respiratory tract than others. That the virus changes location depending on the stage of the disease. And the type of respiratory activity alters how much you omit.
Simple actions like breathing, speaking, singing, coughing and sneezing generate droplets and aerosols of varying size, concentration and viral load.
While we can’t see it, our mouth and our nose are constantly emitting particles which then generates a “plume” around us.
