Comparing MHV infectivity in two droplet sizes. (a) Mean infectious unit per droplet for initial droplet radii at 90% RH and after 5 s levitations, 25 ± 1 µm (M = 2.01, SD = 1.54) and 31 ± 1 µm, (M = 6.97, SD = 2.46). (b) Collected virus infectivity over five minutes at 40% RH, for initial droplet radii 25 ± 1 µm and 31 ± 1 µm.
