    "FACE FACTS

    by Lawrence M. Wein

    Correction Appended

    Stanford, California

    Despite all the attention given to anthrax and smallpox and potential w=
eapons of mass destruction, pandemic influenza is probably the world's most=
 serious near-term public health threat. If a strain similar in affect to t=
he 1918 Spanish flu (which killed tens of millions of people worldwide) eme=
rges in the next several years, it is highly likely that an effective vacci=
ne will not be available during the pandemics first wave, that we won't hav=
e enough antiviral drugs for large-scale prohylactic use, and hospitals wil=
l be too overwhelmed to treat most cases.

    Consequently, as in 1918, we will need to combine medical efforts with =
voluntary and forced social changes - closing schools and churches, cancell=
ing public gatherings, keeping workers at home - to hinder the flu's spread=
. Our government must draw up a plan for educating the public about effecti=
ve nonpharmaceutical interventions like hand washing and face protection li=
ke masks.

    A prerequisite for doing so is determining the biggist culprit in sprea=
ding influenaa: droplet transmission, in which an infected person sneezes o=
r coughs directly into the mouth, nose or eyes of someone who is susceptibl=
e; contact transmission, in which virus is transferred by hands either dire=
ctly, say, through a handshake, or indirectly through an object like a door=
knob; and aerosol transmission, in which evaporated virus-containing partic=
le are inhaled.

    Remarkably, this issue has not been resolved: the Department of Health =
and Human Services' Pandemic Influenza Plan states that 'the relative clini=
cal importance of each of these modes of transmission is not known.' As a r=
esult, the government enthusiastically endorses frequent hand washing - whi=
ch would reduce contact transmission, and costs nothing - but remains nonco=
mmittal about face protection. While the government says that it might be =
beneficial, it doesn't make respirators or masks available. Yet face protec=
tion would guard against aerosal and droplet transmission, and even reduce =
contact transmission by making it difficult to place fingers into one's mou=
th or nose.

    A Stanford graduate student, Michael Atkinson, and I recently performed=
 a detailed study of the routes of transmission, using data on influenza an=
d on rhinovirus, which causes the common cold. Our findings suggest that th=
e dominant mode of transmission for influenza is aerosol - implying that ha=
nd washing will make little difference. This is consistent with the views o=
f leading researchers several decades ago, views that somehow have been for=
gotten by the public health community.

    We found that ventilation, like placing a fan in an open window, and hu=
midifiers (most influenza strains survive in the air for much less time whe=
n the humidity is raised to about 65 percent) can reduce transmission sligh=
tly. Sleeping in separate bedrooms (and working in separate offices) can he=
lp even more.

    But the single most effective intervention is face protection. And beca=
use roughly one-third of influenza transmissions occur before an infected p=
erson exhibits symptoms, these precautions should be taken whenever people =
are in the same room throughout the pandemic period.

    There are two kinds of face protenction: N95 respirators, as worn by co=
nstruction workers, for instance, and surgical masks of the sort worn by de=
ntal hygienists. (The respirators cost roughly a dollar apiece, the surgica=
l masks 10 cents.) Their efficacy in preventing aerosol transmission depend=
s on three factors: the extent to which the face filter prevents virus part=
icles from passing through, how tightly the device fits and - most importan=
t- how long people can be coerced into wearing them.

    To our surprise, we found that the filters in surgical masks, although =
not as good as the filters in the N95 respirators, are still quite effectiv=
e. And although a surgical mask fits much more loosely and allows more leak=
age, it's also more comfortable - and therefore likely to be effective beca=
use it's used more. Wearing nylon hosiery over a surgical mask essentially=
 eliminates the face leakage, making this combination a practical, albiet m=
acabre, alternative. The less comfortable N95 respirators would propably re=
sult in lower compliance.

    The government doesn't stockpile masks and respirators, and the manufac=
turers aren't able to produce a huge number of them quickly. But the way fo=
rward seems clear: the government needs to build up a supply of respirators=
 and masks just as it does with vaccines and antivirals. It should first hi=
re a whiz-bang design company to create, within one month, a surgical mask =
that comfortably adheres to the face, and then decide on the appropriate mi=
x of respirators and masks. Next, it needs to sign contracts with manufactu=
rers to stockpile masks and respirators, relieving the manufacturers of lia=
bility issues.

    Although there is very little technological risk involved (masks and re=
spirators are easier to make and safer than vaccines), several issues need =
to be ironed out. First, the effectiveness of N95 respirators and masks var=
y widely. The government needs to educate the public (the brands are anonym=
ous in the published studies) and should stockpile only the most effective =
brands.

    Also, if respirators and masks are discarded daily, as they are in many=
 hospitals, the national demand during a three-month pandemic could be 10 t=
o 20 billion, and the cost of respirators for a family of four several hund=
red dollars. Such waste isn't necessary. The virus does not survive longer =
than a few hours on the material used for masks and respirators, so they sh=
ould be re-used until they disintegrate.

    The government and the public health community must switch mindsets, fr=
om the current perspective of protecting workers paid to do a dangerous job=
 everyday, to that of providing ciitizens with the tools best to protect th=
emselves during a pandemic.

    It may take 18 months to build a stockpile of respirators and masks, so=
 there is no time to lose. The American people's faith in their government =
will be seriously undermined if, along with larger measures like school clo=
sings, it cannot provide effective face protection for its citizens during =
a deadly pandemic. Masks and respirators may be our main lines of defense d=
uring a pandemic.

    Lawrence M.Wein is a professor at Stanford's graduate school of busines=
s.

    Correction: October 28, 2006

    An Op-Ed article on Wednesday, about preventatives during an influenza =
pandemic, incorrectly stated that the government had not stockpiled masks a=
nd respirators. The Centers for Disease Control has a stockpile of 74.3 mil=
lion respirators and 45.5 million masks."

    Note: In a private communication from Prof.Wein, he stated that a mask =
or respirator should be worn "[a]ny place where you are in a room with anot=
her person (unless you've all been isolated for 5 days from the outside wor=
ld)."

    The end

of=20
    leading researchers several decades ago, views that somehow have been=
=20
    forgotten by the public health community.</P>
    <P>We found that ventilation, like placing a fan in an open window, and=
=20
    humidifiers (most influenza strains survive in the air for much less ti=
me=20
    when the humidity is raised to about 65 percent) can reduce transmissio=
n=20
    slightly. Sleeping in separate bedrooms (and working in separate office=
s)=20
    can help even more.</P>
    <P>But the single most effective intervention is face protection. And=
=20
    because roughly one-third of influenza transmissions occur before an=20
    infected person exhibits symptoms, these precautions should be taken=20
    whenever people are in the same room throughout the pandemic period.</P=
>
    <P>There are two kinds of face protenction: N95 respirators, as worn by=
=20
    construction workers, for instance, and surgical masks of the sort worn=
 by=20
    dental hygienists. (The respirators cost roughly a dollar apiece, the=
=20
    surgical masks 10 cents.) Their efficacy in preventing aerosol transmis=
sion=20
    depends on three factors: the extent to which the face filter prevents =
virus=20
    particles from passing through, how tightly the device fits and - most=
=20
    important- how long people can be coerced into wearing them.</P>
    <P>To our surprise, we found that the filters in surgical masks, althou=
gh=20
    not as good as the filters in the N95 respirators, are still quite=20
    effective. And although a surgical mask fits much more loosely and allo=
ws=20
    more leakage, it's also more comfortable - and therefore likely to be=
=20
    effective because it's used more.&nbsp; Wearing nylon hosiery over a=20
    surgical mask essentially eliminates the face leakage, making this=20
    combination a practical, albiet macabre, alternative. The less comforta=
ble=20
    N95 respirators would propably result in lower compliance.</P>
    <P>The government doesn't stockpile masks and respirators, and the=20
    manufacturers aren't able to produce a huge number of them quickly. But=
 the=20
    way forward seems clear: the government needs to build up a supply of=
=20
    respirators and masks just as it does with vaccines and antivirals. It=
=20
    should first hire a whiz-bang design company to create, within one mont=
h, a=20
    surgical mask that comfortably adheres to the face, and then decide on =
the=20
    appropriate mix of respirators and masks. Next, it needs to sign contra=
cts=20
    with manufacturers to stockpile masks and respirators, relieving the=20
    manufacturers of liability issues.</P>
    <P>Although there is very little technological risk involved (masks and=
=20
    respirators are easier to make and safer than vaccines), several issues=
 need=20
    to be ironed out. First, the effectiveness of N95 respirators and masks=
 vary=20
    widely. The government needs to educate the public (the brands are anon=
ymous=20
    in the published studies) and should stockpile only the most effective=
=20
    brands.</P>
    <P>Also, if respirators and masks are discarded daily, as they are in m=
any=20
    hospitals, the national demand during a three-month pandemic could be 1=
0 to=20
    20 billion, and the cost of respirators for a family of four several hu=
ndred=20
    dollars. Such waste isn't necessary. The virus does not survive longer =
than=20
    a few hours on the material used for masks and respirators, so they sho=
uld=20
    be re-used until they disintegrate.</P>
    <P>The government and the public health community must switch mindsets,=
 from=20
    the current perspective of protecting workers paid to do a dangerous jo=
b=20
    everyday, to that of providing ciitizens with the tools best to protect=
=20
    themselves during a pandemic.</P>
    <P>It may take 18 months to build a stockpile of respirators and masks,=
 so=20
    there is no time to lose. The American people's faith in their governme=
nt=20
    will be seriously undermined if, along with larger measures like school=
=20
    closings, it cannot provide effective face protection for its citizens=
=20
    during a deadly pandemic. Masks and respirators may be our main lines o=
f=20
    defense during a pandemic.</P>
    <P>Lawrence M.Wein is a professor at Stanford's graduate school of=20
    business.</P>
    <P>Correction: October 28, 2006</P>
    <P>An Op-Ed article on Wednesday, about preventatives during an influen=
