Temperature likely has no effect on the transmission of Covid-19

I think they could be measuring the wrong thing. While it may be true that the air temperature doesn't change the biology of the virus, air temperature definitely changes human behavior (what activities we do and where we do them).

Temperature doesn&#x27;t meaningfully affect the spike protein. Neat.<p>Temperature changes droplet dessication, so heated air that is not humidified will generate more aerosols, increasing the transmissibility of the disease.

Study: &quot;Effect of ambient temperature on respiratory tract cells exposed to SARS-CoV-2 viral mimicking nanospheres - an experimental study&quot;. Accessible at: <a href="https:&#x2F;&#x2F;doi.org&#x2F;10.1116&#x2F;6.0000743" rel="nofollow">https:&#x2F;&#x2F;doi.org&#x2F;10.1116&#x2F;6.0000743</a><p>The title of the article describing this research paper is very misleading.<p>Here&#x27;s the primary conclusion of the paper:<p>&quot;Moreover, the ambient temperature changes from 4 to 40 °C had no effect on S-RBD-ACE-2 ligand-receptor binding and minimal effect on the S-RBD protein structure (up to 40 °C), though protein denaturing occurred at 51 °C. Our results suggest that ambient temperatures from 4 to 40 °C have little effect on the SARS-CoV-2-ACE-2 interaction in agreement with the infection data currently reported.&quot;<p>Where I&#x27;m from, the temperature regularly drops to -25 °C in the winter, so this study does not generalize well. In fact, the final conclusion is so weak, it may as well be discarded: &quot;...results suggest...temperatures...have little effect...on the...interaction&quot;.<p>However, this study does prove that saunas and steam rooms kill SARS-CoV-2, as &quot;protein denaturing occurred at 51 °C&quot;, which is well below the average temperature reached in a sauna.

I was under the impression that the mechanism for climate affecting transmission was that virus particles stay alive and aloft longer in colder, drier weather, and not related to receptor binding dynamics. It&#x27;s obviously nice to know that binding dynamics don&#x27;t seem to change with temperature, but the way the headline is presented seems to make a very different claim than the far more specific, and imo, less practically relevant claim that it actually makes.

How about UV light and humidity?

How many degrees is the killer temperature for covid?<p>I have read that hot water does not kill it, but have not found what is upper temperature of breaking protein bonds.<p>Although, it has temperature resistivity - it is not resistant to alcohol and detergents ...

In China it&#x27;s winter and all the major hotspots are in the north (ie. colder regions): Hebei, Heilongjiang, Jilin, Liaoning, Xinjiang, etc.

is it possible that while human typical temperatures might not effect covid specifically, but DO effect other flu&#x27;s and colds... and because THOSE spread easier then that increases the covid vector?

What absolutely guarantees transmission of covid19 is contact between people, interaction in the same spaces.<p>Should probably have minimized that, like a year ago.<p>But I guess they are going to try to find every other loophole until they come back around to &quot;hey if people don&#x27;t interact, they can&#x27;t transmit the virus&quot;.
