WHOの豚インフルエンザに対するマスクの効用についての見解

がここにあった。以下引用。

What about using a mask? What does WHO recommend?
If you are not sick you do not have to wear a mask.
If you are caring for a sick person, you can wear a 
mask when you are in close contact with the ill person 
and dispose of it immediately after contact, 
and cleanse your hands thoroughly afterwards.
When and how to use a mask?
If you are sick and must travel or be around others, 
cover your mouth and nose.
Using a mask correctly in all situations is essential. 
Incorrect use actually increases the chance of spreading 
infection.
