No… No such device exists for Corona Virus at this time. Such a

<div><br class="">
<blockquote type="cite" class="">

PM2, PM10 pollution, and many other things in the air; but
about virus with a rcown?)<br class="">

<div><br class="">
</div>
Detecting a virus in the air is much more complicated than
detecting VOC, CO2, PM2.5 (presumably what you meant by PM2), or
PM10.</div>
<div><br class="">
</div>
<div>PM2.5 and PM10 are a simple size test. CO2 is a molecule that
is easy to detect through a simple electrochemical process. VOC
are</div>
<div>a class of hydrocarbons that all share certain chemical
properties which are easily detected through a simple
electrochemical process.</div>
<div><br class="">
</div>
<div>It should also be noted that such devices even for the
chemicals they can detect require a certain concentration of
that chemical.</div>
<div><br class="">
</div>
<div>On the other hand, a single airborne virion can be enough to
cause a widespread epidemic. If that single virion is “lucky”
enough to find</div>
<div>a compatible host cell and get the cell to start replicating
it, then you can quickly get lots more copies of that virion
which then seek out</div>
<div>additional host cells and additional hosts to make even more,
and so on.</div>
<div><br class="">
</div>
<div>Viruses are not. Viruses are very tiny intracellular
parasites where very subtle chemical differences cause massively
different effects on humans.</div>
<div><br class="">
</div>
<div>They consist of an RNA or DNA genome surrounded by a
protective virus-coded protein coat. More information here: <a
href="https://www.ncbi.nlm.nih.gov/books/NBK8174/" class=""
moz-do-not-send="true">https://www.ncbi.nlm.nih.gov/books/NBK8174/</a></div>
<div><br class="">
</div>
<div>Currently, the best we can do is a test to detect coronavirus
infection in a person after they are infected and symptomatic.</div>
<div><br class="">
</div>
<div>So for now, stay indoors with your family and if you’ve got a
sick sense of humor like I do, play one or more of the Pandemic
board games (if you happen to own them).</div>

It's the price we pay for hyper-connectedness (not
trying to coin a<br class="">
phrase, hehe).<br class="">
<br class="">
Everybody (especially the kids) lives on their device
99% of the time.<br class="">
If you're not on their device, you are not relevant to
them.<br class="">
<br class="">
When was the last time you bought a newspaper? How many
times do your<br class="">
kids watch the news, either on TV or their device? But
they are all over<br class="">
WhatsApp, Instagram, Twitter, SnapChat, WeChat, et al.
And even if they<br class="">
have the "News" app on their phone, they probably have
never opened it.<br class="">
If they opened it, they didn't find value in it.<br
class="">
<br class="">
On average, the we (and the kids) will give your app two
tries; if we<br class="">
don't like it, you're out - which explains why we all
have 3,000 apps on<br class="">
our phones, but only use 2 or 3 of them most
consistently.<br class="">
<br class="">
Whoever wants to get professional and verified
information out (to the<br class="">
kids who live on their devices) needs to find a way to
do so in a manner<br class="">
we find relevant, otherwise we'll simply keep trading
mis-information<br class="">
for whatever reason we feel gives us value.<br class="">
