Generally the reason to wear a mask outside of a healthcare setting is to protect other people rather than yourself.  If you are infectious but presymptomatic/asymptomatic the mask will reduce the amount of droplets and aerosols you give off.

I don't think it is clear that the mask will protect the wearer unless used properly (most that I've seen out and about are not) and in conjunction with other protection measures (frequent hand washing).
