Uploaded and Shared in Youtube by: NEJMvideo — Sequential schlieren images during the cough were recorded at 3000 frames per second. A maximum airspeed of 8 m per second (18 mph) was observed, averaged during the half-second cough. Several phases of cough airflow are revealed in the figure. The cough plume may project infectious aerosols into the surrounding air. There is an increasing interest in visualizing such expelled airflows without the use of intrusive methods because of concern regarding the transmission of various airborne pathogens, such as viruses that cause influenza and the severe acute respiratory syndrome (SARS).
