it on :)

Maybe. Unfortunately, many respiratory infection agents are viruses, and
the masks are less effective with virus aerosols.  Also, some people are
carrying the disease and don't know it (aren't sick enough yet), so you
wouldn't know to put the mask on.

But don't neglect skin-to-skin and skin-surface-skin transfer: it's a
*large* percentage of the transmission vector. You think it's random
that toddlers get sick *WAY* more often than adults do and they are
constantly putting their hands (and other stuff) in their mouths?  Wash
your hands often, encourage others to do so, and carry around a small
bottle of that hand sanitizer to use when a bathroom is inconvenient.
