CDC-Facemask and Respirator Use in
Community where SWINE FLU DETECTED
http://www.cdc.gov/swineflu/masks.htm
--------------------------------------------------------------------------------
CDC is calling N95 close fitting masks "RESPIRATORS" and those loose
fitting, flat, usually folded pleat, surgical, or other material
"MASKS".
[This is what I purchased on eBay: GERSON 2130 N95 RESPIRATOR BOX OF
20 MASK NEW Item number: 180235452261 These are also good:
3M 8200 N95 RESPIRATOR - 1 BOX 20 MASK 3M8200 Item number:

They seem to be advising DON'T rely on any mask or respirator and KEEP
at least 6 foot away if you MUST risk exposure, and LIMIT YOUR TIME,
EVEN WITH MASK OR RESPIRATOR that you are in infected area. Basically,
I translate this official advice to; avoid groups and Stay out of
stranger contact even if you wear a respirator or mask.
If there is ANY CHANCE you WILL come near an infected person WEAR A
RESPIRATOR, NOT A FACEMASK!!
Interim Recommendations for Facemask and Respirator
Use in Certain Community Settings Where Swine Influenza A (H1N1) Virus
Transmission Has Been Detected
April 26, 2009 01:00 ET
This document provides interim guidance and will be updated as needed.
Detailed background information and recommendations regarding the use
of masks and respirators in non-occupational community settings can be
found on PandemicFlu. gov in the document Interim Public Health
Guidance for the Use of Facemasks and Respirators in Non-Occupational
Community Settings during an Influenza PandemicExternal Web Site
Policy..
Information on the effectiveness of facemasks1 and respirators2 for
the control of influenza in community settings is extremely limited.
Thus, it is difficult to assess their potential effectiveness in
controlling swine influenza A (H1N1) virus transmission in these
settings. In the absence of clear scientific data, the interim
recommendations below have been developed on the basis of public
health judgment and the historical use of facemasks and respirators in
other settings.
In areas with confirmed human cases of swine influenza A (H1N1) virus
infection, the risk for infection can be reduced through a combination
of simple actions. No single action will provide complete protection,
but an approach combining the following steps can help decrease the
likelihood of transmission. These actions include frequent handwashing,
covering coughs, and having ill persons stay home, except to seek
medical care, and minimize contact with others in the household.
Additional measures that can limit transmission of a new influenza
strain include voluntary home quarantine of members of households with
confirmed or probable swine influenza cases, reduction of unnecessary
social contacts, and avoidance whenever possible of crowded settings.
When it is absolutely necessary to enter a crowded setting or to have
close contact3 with persons who might be ill, the time spent in that
setting should be as short as possible. If used correctly, facemasks
and respirators can help prevent some exposures, but they should be
used along with other preventive measures, such as avoiding close
contact and maintaining good hand hygiene. When crowded settings or
close contact with others cannot be avoided, the use of facemasks1 or
respirators2 in areas where transmission of swine influenza A (H1N1)
virus has been confirmed should be considered as follows:
1. Whenever possible, rather than relying on the use of facemasks or
respirators, close contact with people who might be ill and being in
crowded settings should be avoided.
2. Facemasks1 should be considered for use by individuals who enter
crowded settings, both to protect their nose and mouth from other
people's coughs and to reduce the wearers' likelihood of coughing on
others; the time spent in crowded settings should be as short as
possible.
3. 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.
These interim recommendations will be revised as new information about
the use of facemasks and respirators in the current setting becomes
available.

1 Unless otherwise specified, the term "facemasks" refers to
disposable masks cleared by the U. S. Food and Drug Administration
(FDA) for use as medical devices. This includes facemasks labeled as
surgical, dental, medical procedure, isolation, or laser masks. Such
facemasks have several designs. One type is affixed to the head with
two ties, conforms to the face with the aid of a flexible adjustment
for the nose bridge, and may be flat/pleated or duck-billed in shape.
Another type of facemask is pre-molded, adheres to the head with a
single elastic band, and has a flexible adjustment for the nose
bridge. A third type is flat/pleated and affixes to the head with ear
loops. Facemasks cleared by the FDA for use as medical devices have
been determined to have specific levels of protection from penetration
of blood and body fluids.
2 Unless otherwise specified, "respirator" refers to an N95 or higher
filtering facepiece respirator certified by the U. S. National
Institute for Occupational Safety and Health (NIOSH).
3 Three feet has often been used by infection control professionals to
define close contact and is based on studies of respiratory
infections; however, for practical purposes, this distance may range
up to 6 feet. The World Health Organization uses "approximately 1
meter"; the U. S. Occupational Safety and Health Administration uses
"within 6 feet." For consistency with these estimates, this document
defines close contact as a distance of up to 6 feet.
