Scientists in China are saying that mice are a likely source of the Omicron variant. The virus appears to be well adapted to infect mice, which is a major change from earlier variants.
Back in August scientists reported that they had genetically modified the virus to infect mice:
Scientists had previously reported that both the original strain of SARS-CoV-2 as well as its newly emerged variants did not infect mice . . . This has caused some hindrance in COVID-19 research because the mouse (Mus musculus) is a commonly used animal model to study infection. Therefore, the virus had to be modified via various techniques, e.g., sequential passaging in mouse lung tissues and modifying the receptor-binding domain (RBD).
Of course, any suggestion that a COVID variant originated in a lab has been repeatedly fact-checked as false, so these reports must be just a coincidence . . .
The original excuse the Chinese gave was that COVID came from eating bats in their wet market. Don’t take me too serious. I don’t and good Sunday morning to you Ms. Miller.
Fast forward to 2009, and we weren’t allowed to sweep the barracks at McGregor Range because fear of the hanta-montana virus being kicked up. We had to wet mop the dust. lol
