  This study only finds that N95 are not more effective than surgical masks. It does not measure the effectiveness of surgical masks vs nothing. Did you actually read the study before posting a link to it? It's worth also noting that this refers to healthcare workers. The considerations are totally different here, because the likelihood that they'll come into close contact with an infected person is pretty close to 100%. The likelihood that a member of the public will in most Asian countries with 20 or so cases and a few tens of million people is more like 0.00001% give or take a couple of orders of magnitude.
