Those links don't allege what you are saying at all... the second expressly disclaims any such conclusions given the size of the error bars, and the first talks about the protective effect of an active infection, not a simultaneous epidemic. Needless to say, only a tiny fraction of humanity has been actually infected with covid at any one time over the past year.

Do you have a link to someone alleging this for covid? I'm worried this is spin that you picked up from a source that has an interest in opposition to covid mitigation practices.

I thought exactly the same. I recently had a lengthy discussion about viral interference here on HN only to learn that the person didn't want to see evidence that the mitigation measures (i.e. associated human behaviour change!) are effective - not only for SARS-Cov-2, but for a broad range of viral (and non-viral!) infectious diseases.
