And again, ticks only feed once per developmental stage, right?

So say the larva feeds on an infected host.

That same larva will molt into a nymph.

And then that nymph is now infected and looking to feed.

And that's the first time that it can infect other hosts like us.

So that's the temperature of a human, right, when I'm healthy?

Exactly.

And this temperature trigger, right, your healthy human blood, tells the bacteria in the tick that it's time to replicate.

It's time to start moving from the stomach to the salivary glands of the tick.

And that's when the transmission process begins.

And that's why the CDC gives this recommendation that you should try to find and remove ticks, if possible, within the first 24 hours.

And that's how ticks transmit Lyme disease.

Yeah, I wanted to know this too.

So I talked to a disease ecologist.

Her name is Jean Cao, and she specializes in tick-borne diseases at Michigan State.

She told me there's a variety of different factors at play here, right?

Temperature, humidity, habitat, and we're not going to get into all of them.

But one big one is that Lyme seems to be more endemic in the North, maybe just because it's been circulating longer.

So your probability of getting infected is higher.

Yeah.
