@cjd Sadly Scientific fraud is not entertaining
You assume spread and you believe it. I did too before I started verifying it. You claim it yet can't prove it experimentally, yet your burden of proof.

contagion myth alone was experimentally disproven long time ago search # tag "rosenauexperiment" likewise no one proved otherwise

There is no short version. Everyone of us had to do weeks of research and unlearning lies. You can't learn something without research.
All you need to do is look into our arguments. I can't do it for you.

Short: Germ theory is religion Terrain model is science. You must go into the radix of problem, understand what constitutes a proof for a virus and try to find it opening random study like I and many tried and failed in 2020. It's only fulfilling kochs postulates. Problem is they were never fulfilled. Virologists even admit it. Without that all other arguments based on this premise are invalidated, like sequencing odysee.com/@OzFlor:7/Lanka:a

Read the book Virus Mania, most of us red it. It's for people like you. More than thousand verifiable sources. You will unlikely have any qustions.

Alternatively you can start with articles of ex-virologist [because he realized virology is a fraud] Stefan Lanka wissenschafftplus.de/cms/de/wichtige-texte
