Yes - it’s increasing everywhere, with climate change helping it along. Lyme and other tick-borne infections have a tendency to be under-reported, so the real infection rate in any area is likely to be higher than the numbers published - they can be tricky to diagnose because the symptoms can be so varied and mimic lots of other things, and of course other things can be in the mix too. Unfortunately, blood tests for these infections are not 100% accurate yet, so negative test results aren't a cast iron guarantee of no infection. Because you’ve seen ticks on Katie and because of her symptoms, perhaps your vet might consider a course of antibiotics for her, even if she gets a negative result. Thank goodness she's got you fighting her corner to get to the root of what’s going on.
