A subject coughing in a cyclic incident. A qualitative examination of airborne droplet transmission with and without wearing a surgical mask. The figures show the results at 2, 3, 4 and 5 seconds. Wearing a surgical mask that exhibits initial efficiency of approximately 91% cannot prevent the transport of the saliva droplets away from the subject. Many droplets penetrate the mask shield and some saliva droplet disease-carrier particles can travel more than 1.2 meters. For visualization, the droplets were scaled by a factor of 600 compared to their actual size. The environmental conditions are zero wind speed, ambient temperature 20 degrees C, pressure of 1 atmosphere, and relative humidity 50%. The mouth temperature is 34 degrees C, and the face skin temperature is 32 degrees C.
