<h3 id="expanderHead" data-jsid="expanderHead">Hi All<br>
</h3>
<h3 id="expanderHead" data-jsid="expanderHead">I have noticed
a barrage of anecdotal evidence supporting mandatory masking
but this is not sound science free from bias. An anecdote
from a medical expert is still an anecdote. <br>
</h3>
<h3 id="expanderHead" data-jsid="expanderHead">Based on the
analysis of available randomized trials with verified
outcomes on the effectiveness of masks in reducing
transmission of respiratory viruses scientists at the <u>Ontario
Civil Liberties Association </u>have concluded that there
are no statistically significant indicators that masks offer
protection either for the wearer or others in the prevention
of respiratory illnesses caused by aerosolized viruses. <br>
</h3>
<h3 id="expanderHead" data-jsid="expanderHead">Despite the
reality of the evidence the commonly accepted belief is
outrage at non compliance to mandatory masking. Canadian
society was successful in dropping infection rate without
masks and yet fear is being ramped up to enforce mask
wearing compliance. We have lost all sense of the negative
consequences of mask wearing. Most absurd is to feed this
culture of fear in our class rooms. Come September grades 4
and over will have to wear masks for the full school day.<br>

<li> <span id="bcr_rptStory_cslStory_0">Science clearly
shows face coverings of various kinds do little if
anything to prevent respiratory illnesses caused by
aerosolized viruses</span> </li>
<li> <span id="bcr_rptStory_cslStory_1">Influenza viruses
— coronaviruses that cause the common cold and
SARS-CoV-2 — all spread via the air, not just via
droplets or touching contaminated surfaces. Preventing
droplet contamination does not mean you also prevent
the transmission of the aerosolized virus</span> </li>
<li> <span id="bcr_rptStory_cslStory_2">SARS-CoV-2 is a
beta-coronavirus with a diameter between 60 nanometers
(nm) and 140 nm, or 0.06 to 0.14 microns
(micrometers). Virus-laden saliva or respiratory
droplets expelled when talking or coughing measure
between 5 and 10 microns</span> </li>
<li> <span id="bcr_rptStory_cslStory_3">N95 masks can
filter particles as small as 0.3 microns, so they may
prevent a majority of respiratory droplets from
escaping, but not aerosolized viruses. Lab testing has
shown 3M surgical masks can block up to 75% of
particles measuring between 0.02 microns and 1 micron
while cloth masks block between 30% and 60% of
respiratory particles of this size</span> </li>
<li> <span id="bcr_rptStory_cslStory_4">Regardless of the
mask, it will not prevent you from exhaling or
inhaling the aerosolized virus, but cloth masks are
clearly the least preferable option if you actually
want to reduce the spread of infection, as their
ability to block respiratory droplets is also limited</span>
