[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?

Vett LloydGUEST
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.

Vett LloydGUEST
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.

Vett LloydGUEST
So they're sometimes called nature's dirty needle, and that's a pretty good description of what they do.

One question that just popped up in my head, where are ticks most likely to be?
