I love being outdoors, and I love being outdoors with my children and teaching them how beautiful and special nature can be. So I knew that a day would probably come eventually when one of us would be bitten by a tick. My daughter has a morning of wood time every friday and we take hikes and walks in the woods fairly frequently. As a result, I am very very careful to do tick checks at the end of any day where there might be a risk.
Since I’ve been feeling much better (and in fact finished the unique treatment I began this spring), I had a hike planned with my family in the swiss mountains. I let my guard down and didn’t insist on socks around pants until I realized we were heading off trail (and found my missing tick spray); we didn’t wear light colors, and I generally relaxed more than usual. I should know better.
Then on the train ride home, we discovered an adult deer tick crawling down my husband’s arm. So when I got home I insisted on doing a very very thorough tick check on each child, and gave them a hot bath to boot (on the theory that if I missed one maybe it would drown :). I also checked my husband and he checked me.
As you’ve probably guessed by now, we found a tick. A nymph tick, attached to my hip. Interestingly, I had experienced some discomfort in the area near the tick during the train ride home (and attributed it to the fact that my back went out last week on that side). After finding the tick, I can’t help wondering if perhaps it was something else (I’ve had no back pain for a week and when I had it it was quite a different sort of pain). In any case, once the tick was discovered I did the following:
2) I followed the instructions carefully, with my husband’s help, and put the tick in a ziplock bag
3) I emailed my doctor, a tick expert, and asked what he knew about the standard of care in this situation. He pointed me at a very interesting paper titled “Accelerated transmission of Lyme disease spirochetes by partially fed vector ticks” . The article shows that a nymph tick attached for as few as 8 hours can transmit Lyme disease spirochetes (to mice) if it was previously attached to an infected host and partially fed.
4) The normal treatment if you catch infection immediately is 3-4 weeks of antibiotics (usually doxy), according to the ILADS guidelines (the standard I choose to use when considering treatment options).
I considered the situation. My tick was was attached for 8 hours or less (I don’t know when I got it, only when my hike started), and was a nymph tick. I don’t know whether it had a previous feeding or not, but I do know that if it did, there’s a significant chance that I could have acquired an infection.
As a result, I decided to treat prophylactically, and simultaneously to get the tick tested for Lyme disease (the test available here only tests for that, but co-infections are apparently less common in Switzerland). If it comes back negative, I can reconsider whether to continue the antibiotics.
This leaves me with one important question: Have I made the right larger choice. Is the risk of Lyme disease, and the concern over getting it, worth being out and about in nature? So far, my answer has been yes. But the outcome of today’s events may affect how I think about all this. I am most thankful, though, that it was myself and not a family member that was bitten. I at least know what needs to be done and am willing and able to do it.
