[laughs] What are some of the tick-borne illnesses that are most relevant to search and rescue teams? And how quickly can symptoms appear after exposure?
11:53
Okay.
11:54
So ticks are basically crawling bags of pathogens.
12:00
What they do is they're parasites, so they live exclusively on blood, and n- if there were no humans around, what they do is they take blood from wild animals and then bite another wild animal, take some blood from that.
12:16
But while they're taking blood, they get pathogens, and then when they bite another animal, they squirt back the pathogens from the first animal into it.
12:25
So they're sometimes called nature's dirty needle, and that's a pretty good description of what they do.
12:32
They move pathogens, disease-causing microbes from one animal to another.
