Thanks. I need to sort one of those out with my children.our pre-designated gathering point and wait!
I have N95 masks but all my colleagues and people around me only have surgical masks. N95 are clearly better in that the air, and coronavirus, can't get in at the sides. However, the research I quoted aboveDid you get an N95 mask?
Goes on to quote other research in this way
"A randomized clinical trial has reported N95 respirators vs medical masks as worn by participants in this trial resulted in no significant difference in the incidence of laboratory confirmed influenza.4"
Where the research quoted is
N95 Respirators vs Medical Masks for Preventing Laboratory-Confirmed Influenza in Health Care Personnel
This cluster randomized clinical trial compares the effect of N95 respirators vs medical masks worn by health care personnel for prevention of workplace-acquired influenza and other viral respiratory infections in geographically diverse, high-exposure outpatient settings.
"In this pragmatic, cluster randomized clinical trial involving 2862 health care personnel, there was no significant difference in the incidence of laboratory-confirmed influenza among health care personnel with the use of N95 respirators (8.2%) vs medical masks (7.2%). " (i.e. a non significant differences)
I think that as SARS research Laurie Garret's advice implies
As China’s epidemic continues to spread, things may seem scary. Here are 10 simple precautions that can protect you from contracting the coronavirus.
If (as Dr. Perencevich warns linked) you fiddle with your mask then a mask can make things worse (especially the surgical type which allow fingers underneath them I presume) but if you are a medical professional trained not to do so, then either mask, and gloves, will help people avoid face touching.
You have to be pretty close and unlucky for someone's cough or sneeze to go straight into your nose or mouth. Most of the time it is via hands, and often a surface. That said I was glad of my N95 while proctoring an exam today and would wear one in any crowded, or care-giving situation.
