Short-range Transmission1m2m4m536421Risk of transmission through direct exposure to respiratory droplets which settle on surfaces and people touch.5Large droplets settle to the ground in a few seconds.3Opening windows and doors will provide a good flow of fresh air.7Small droplets and aerosols can end up in the eyes, mouth or nose of people standing nearby. These aerosols can remain suspended in the air for differing amounts of time, especially indoors with no ventilation.6Medium particles or droplets which have the ability to travel and infect people below 2m.4Individual susceptible to infection.2Infected individual (not wearing a face covering) exhales tiny contagious particles.18Avoid using ventilation systems which only recycle air. Blowing air directly at another person in a closed space increases the risk of the virus spreading from one person to another.89WG4324797
