I was listening to an old radio drama where there was a fictional (I think) substance that was a contact poison in its powder form, but not when it was mixed in water. So the way to use it diabolically was to carry it around diluted, paint it on what your target would touch, and then be sure not to touch it yourself after it dried. This got me thinking about cloth masks that are worn for a long time or reused without sitting several days. So, the mask does what we're hoping it does and catches the droplet with the virus because the droplet is well above the minimum size. After the droplet dries, is the virus just sitting on the mask and capable of getting inhaled through?
For other contaminants, yes. Like, say mold spores - if you wear a mask to protect yourself from mold, and then handle the mask afterwards, you can contaminate yourself.
Coronaviruses, however, are not hardy in that way. If the drops they are in dry out, they quickly die.
Mind you, some viruses do survive in such a state. Just not coronaviruses.
