Other syndromes transmitted by deer ticks are less common than Lyme, but also more likely to be lethal. There is no cure or preventative treatment for any of these. And, we may contract more than one disease simultaneously from a single deer tick.
I hate to sound like an alarmist. If anything, I tend to be a bit too casual about infection, insects, exposure to bacteria and viruses. However, I’m trying to be responsible here because I do know that deer ticks tend to be most present in the fall and spring, so we are entering peak season.
Best practice: if you’re outside during the day–particularly in the woods or near brushy areas–check yourself for deer ticks and try to have someone scan your back.
