Does any of the AYUSH systems depend on Germ Theory?

Would like some insights from AYUSH specialists if any of the systems (Ayurveda, Yoga, Siddha, Homeo, and Naturopathy) are agreeable to, and/or depend on the Germ Theory? Of course, I do not mean in the same sense as Allopathy, but some concept of their own?

For example, Allopathy/Pharma system of today is heavily reliant on Germ Theory, that germs (bacteria and viruses) cause diseases. However, its experimental framework is weak and highly defective. For example, NONE of the papers claiming "isolation" of COVID-19 mentioned negative controls (control experiments). The very fact that these are absent from the papers gives a strong suspicion on their validity and claims. Similarly, NOBODY till date sequenced a full Viral genome, all that they actually do is piece together fragments of genetic sequences (contigs) from millions of "viral particles" and build a genome in the computer. Such a genome (or a virus) is never found in nature. NOBODY ever could isolate a virus directly from a patient breath, sputum, blood or any other tissue or fluid, all they actually do is "inoculate" cell culture and demonstrate dubious CPE (cytopathic effects) - which may as well have been caused by the use of Antibiotics and decantation of nutrition post application of the antibiotics. Starved of food, any living being or tissue or cell would certainly die, why does it need a hypothesis of a virus? And, finally, NOBODY really proved a contagion so far. Louis Pasteur, to prove that "rabies" is a contagion, tied up dogs to poles their feet barely touching the ground. Sucked almost 1/3of the brain of the claimed "mad dog" and injected into a healthy dog's head directly. He did this twice and one dog died and the other became mad - and thus he proved that rabies is a contagion. Common sense would tell any such thing can happen even if so much plain water is injected into a dog's head, what is the need of an "infected" dog's fluid? Today, nobody even performs a good experiment. When they indeed do, they do the same old barbaric act of injecting fluid into the animals' head directly or by puncturing the eyes.

So, I am interested to hear, how AYUSH systems treat the question of a disease that can be observed among many at one time, for example, 'seasonal flu', or the present COVID. Are flu and current flu like illness (COVID) caused by germ(s)?
