A while back I read the prevalence of masks on asia ladies was so men would not bother them out in public or on the bus.

This is what I'm saying!

A mask may help with face touching. But a person also needs glasses/goggles to avoid touching their eyes.

How about your mouth and nose?

Indeed the following started to become more popular in Hong Kong and China (might be originated in Korea as said):

Or this on the extreme side:

I haven't seen any reputable sources that say a non-95 mask will prevent coronavirus spread and protect health care workers or others from mist. In fact, everything I've seen says the opposite - only the N95 does (if properly fitted/worn).

A general medical advice in Hong Kong since 2003 SARS, so has been carried on this time.

The CEO of Hong Kong SAR government had once said mask (surgical mask) should reserve for the sectors of mostly needed trying to release the pressure on local mask supply shortage, but had eaten her word very soon.

Now, currently in Hong Kong, N95 is for the most front line medical staff who have the most supply as needed. For non isolated hospital wards staff, N95 (in regulated supply) and mostly surgical mask only. Also other personals like first responders, those responsible for quarantine quarters, or medical staff stationed in airport to deal with incoming passengers etc are mostly using surgical masks only. Touch wood so far only 1 latest case (a doctor stationed in airport checkpoint) has been infected since the outbreak so far.

Don't look down that surgical mask. A qualified one is making up of 3 layers. The outer layer is WR to stop the direct face to face virus spray, the middle layer stops microbes from entering or exiting the mask, and the inner layer as a moist absorber (breath of wearer) to keep the filter ability of the middle layer. Not as effective as N95 of course, but good enough if we can wear it properly, keep certain social distance etc.

It is not a 100% protection, but while it can reduce the risk (not totally ineffective) under non ultra high risk area, why still resist it?
