To WHO and all agencies denying the efficacy of masks:

When people don't wash their hands properly, it could lead to the result that they 

are still infected. Would you then tell people not to wash their hands because of this ?

No, you guide them how to wash hands correctly.

When you inform the public that people showing symptoms should stay home

and be quarantined,and that people allowed to go out are asymptomatic and not

likely to spread the disease,  why bother social distancing ?

When you said more scientific evidence is needed before you can decide whether

or not poeple should wear masks, don't you know poeple keep being infected and

killed everyday ?

Would it do any harm to people if it's recommended preemptively that they

wear maks ?

What if it turns out in six months from now that studies show it works ?
How many people will have been killed due to the incation ?

Now, do you see the paradoxy and stupidity of telling people not to wear masks ?

These experts are just too well-trained to think outside of the box.

Taking maximum precaution wouldn't hurt as much as the other way around.
