This Podcast Will Kill You · Ep 216 Cyclospora: Explosive Diarrhea Everywhere · 21 Jul 2026 podcast

Their appetite is down.

And when I say it can go on for a long time, I mean this can go on for weeks to a month to six weeks if it's untreated.

Yes.

So it's usually at least two weeks of illness and like five to 15 explosive liquidy stools a day, not minor, that can go on for at least two weeks if it's untreated.

But often it's lasting longer than two weeks, right?

Like a month, five, six weeks.

Yeah.

I love that you asked me this question.

I don't know.

The only thing I saw in the literature of how many parasites does it take is that we think I wish I had written the exact quote, but it was like, we think that it's quite low.

Yeah.

So we don't really know, but it's probably just a handful of these individual oocysts, right?

Each one has four sporozoites that are causing infection.

Then they're replicating asexually before doing the sexual reproduction thing.

So I couldn't find a specific infectious dose.

And similarly, I don't have an exact number on how many oocytes are you pooping out, but what makes this really challenging is that it's not a lot.

This is not cholera or norovirus where you're releasing thousands, tens of thousands.

It is low numbers of these oocytes and it can be sporadic.

So you might, even though you're having diarrhea continuously, you might not be releasing oocytes in every stool.

And it's in part because of this, it's not every single parasite that's getting excreted, right?
