From an MSNBC article linked upthread:
Does anybody remember a single incident of people on planes and walking down the street wearing masks in the US? Because I sure don't.
And I remember flying during that period of time and nobody in the (U.S.) airports were wearing them, either.
Those that will benefit from masks, are the surgical supply companies. Masks work well if you are trying to protect others from pathogens that "you" may have. I learned in nursing school that the protective benefit to the wearer of the mask probably doesn't exceed 20 to 30 minutes. In the process of inhaling and exhaling, the mask becomes moist and can conduct bacteria and certainly viruses right through the mask. If you can breathe through it, you can eventually get infected through it. Its not the same as containing droplet and aerosol contamination from yourself to someone else.

- or Wow! Out of the entire population of the United States there are currently only 68 confirmed cases..
