CIDRAPの見解とCDCとどちらを言っているのでしょうか。
CDCであれば、そこで参照されているページに行けば記載してあります。

When close contact3 with others cannot be avoided, the use of facemasks1 or respirators2 in areas where transmission of novel influenza A (H1N1) virus has been confirmed should be considered as follows:
1.Persons who are at high risk of complications from novel influenza A
(H1N1) infection (for example, persons with certain chronic medical
conditions, children less than 5 years, persons 65 or older, and
pregnant women) should consider their risk of exposure to novel
influenza if they attend public gatherings in communities where
novel influenza A virus is circulating. In communities with several
reported cases of novel influenza A (H1N1) virus infection, persons
who are at risk of complications from influenza should consider
staying away from public gatherings.
2.Based on currently available information, for non-healthcare settings
where frequent exposures to persons with novel influenza A (H1N1)
are unlikely, masks and respirators are not recommended.
3.Persons who are ill with influenza-like symptoms should stay home
and limit contact with others as much as possible. When not alone
or in a public place, protect others by wearing facemasks1 to
reduce the number of droplets coughed or sneezed into the air
and the time spent in crowded settings should be as short as possible.
4.Respirators2 should be considered for use by individuals for
whom close contact with an infectious person is unavoidable.
This can include selected individuals who must care for a sick
person (e.g., family member with a respiratory infection) at home.
先に上にあげたコメントに変わりありません。
frequent exposuresですから、単なるexposuresではないですよね。
4はrespiratorで、3はmaskです(感染者)。
一般の非感染者にmaskを推奨する記述はありません。
まあ、should be consideredとされる行動規範なので、これ以外の
ケースで有効かを触れているわけでないとの反論が出るかもしれ
ませんけど。
