the parasite theory got me thinking that vetrenarians might be better sources for what's going on than doctors

>Veterinary science helps human health through the monitoring and control of zoonotic disease (infectious disease transmitted from nonhuman animals to humans)
then the parasites being inside us would be a form of zoonosis. It sounds like they coined the word to make you think it only applies to zoo animals, or the disease can only be passed from a big animal.

But zoonosis is still focused on human transmission so it's subject to political pressure. What about the vet study of the animal's health, probably focussed on parasites they same thing that infects human.

You get into it though and they're calling ringworm a "fungal" infection.

Might be interesting to consult with a vet about this.
