Frequent hand washing and covering one's mouth and nose when coughing and sneezing reduce transmission, as does wearing a mask.
Respiratory droplets are produced naturally as a result of breathing, speaking, sneezing, coughing, or vomiting, so they are always present in our breath, but speaking and coughing increase their number. [1] [2] [3] Droplet sizes range from < 1 μm to 1000 μm, [1] [2] and in typical breath there are around 100 droplets per litre of breath. So ...
