New report flags Lyme-positive ticks on Sonoma County hiking trail
"If that sounds like a dry lab statistic, here's the part you'll actually remember: Lyme is one of those infections that can make you feel like you got hit by a truck. Feverish. Wiped out. Achy. Foggy. And it can start as the kind of "I'm just run down" stretch that people blow off for a week or two - especially when it's winter and everyone's tired anyway."
"Here's what "pooled" means: adult ticks aren't always tested one-by-one. The District writes, "A maximum of five ticks were placed in each pool." So if a pool tests positive, you don't know if one tick in that tube was infected or if all of them were - you only know at least one was. That's why MIP is the floor, not a dramatic overstatement."
Ticks collected along Umbrella Tree Trail at North Sonoma Regional Park tested positive in pooled assays for Borrelia burgdorferi, yielding a minimum infection prevalence (MIP) of 7.41% from two positive pools out of 27 adult ticks. Lyme disease can produce severe, flu-like symptoms and may begin with mild fatigue that is easily dismissed. MIP is calculated as (number of positive tick pools/total ticks tested)*100 and is conservative because adult ticks were grouped with up to five ticks per pool. A positive pool indicates at least one infected tick, signaling infected ticks are present where people commonly recreate.
