Not all dogs are strictly pets, though. I can see a hunting dog in the field doing its work, the dog being exposed and its human, not – because the dog encounters a wild animal that its human does not.
Taiwan tho, was a lab animal deliberately infected with Covid. Not a ‘wild mouse’
Life itself is risky.
Anyway, it is worth living, if possible wholly, however high these risks can be.

Thank you.
It seems like the story of my life is being forced to conform to other people’s ideas of acceptable risk. Sometimes I just want to shout, “Who gave you the right to impose your fear on everyone else?”

Thank you for that scientific link: 10% seropositivity for coronavirus in mice in the Canary Islands - interesting statistic.
I wonder about omicron in particular due to these two papers:
https://www.biorxiv.org/content/10.1101/2021.12.14.472632v1
and this paper from earlier on deer mice in particular

If there has been a recent study on the actual SARS-Cov-2 seropositivity in wild deer mice in NA (or anywhere, for that matter) I would be very interested to read it, especially since omicron is speculated in this peper to have originated in mice by some scientists. (See bioarxiv link posted elsewhere in this forum)
Collectively, our results suggest that the progenitor of Omicron jumped from humans to mice, rapidly accumulated mutations conducive to infecting that host, then jumped back into humans, indicating an inter-species evolutionary trajectory for the Omicron outbreak. <
Weird… That was pretty interesting news to me. I wonder if omicron was still passed by respiration, when it jumped between mice and humans?
Other than lab mice, how would people get close enough to a mouse to breathe it’s exhalation?

Okay… so, saliva to blood is a SARS infectious pathway? Not just respiratory?
Arghh… then I wonder if mosquitos and fleas will become a source of SARS.
Here is a study reported by the Natl. Inst. Of Health describing genetic and molecular findings for the evolution of omicron from either animal hosts (mice) or immune compromised humans with long Covid .
It’s way over my head, but others may be able to suss it out more thoroughly.
What if new viruses like SARS-CoV-2 are the earth’s antibodies as it tries to shake this fever (global warming)?

Nice image, though I don’t begin to believe it.
People chose to expose themselves to new viruses against which ‘I will rely on my natural immunity’ doesn’t work.

Covid seems to be behaving quite similar to Spanish flu with all the caveats for changes to mobility and medical technology.
There’s a whole ecology around viruses and bacteria and animal hosts. Like there’s some evidence the common cold beats out covid (at least delta) if they are both infecting someone. Stuff like that. We know so little still.

Although the origin of Sars-CoV-2 is not known for sure, it’s looking like a zoonotic origin is more likely than a lab leak. See https://sandwalk.blogspot.com/2021/10/the-case-for-natural-origin-of-sars-cov.html
