Figure 3.. Schematic illustration of a virus-laden respiratory droplet after being released by an infected person (A) and after the loss of some water content through evaporation (B). The water part of the droplet is colored light blue in A while blue in B. Yellow “bubbles” of various sizes indicate the nonaqueous components such as salt, proteins, and surfactants. The virus particles are drawn as core-shell structures with the core colored in red.
