Alicia, If you are asking about whether people with pets tend to be at a greater risk for developing ms, I cannot say for sure. I do know that I was dx'd with ms after sharing my home for 6 yrs with 2 cats and 2 dogs.
[outdoors much of the time]
The yr I was dx'd with ms was a record yr for vector-borne illness, and 3 other adults in my neighborhood were alsomdx'd with ms.
[very suspicious to me] My neuro says lyme disease and co-infections are rare. I live in a wooded/semirural area in a highly endemic county in MN, and recall many a spring yanking deer ticks off my pets[and my kids for that matter]. Our house was crawling with them, even had my PCP pull one off my arm.
However, I did not get the erythema migrans or bull's eye rash, and tested neg for lyme, etc. **le sigh**
You know how, in your gut, you know something is wrong but you just can't prove it?
I thought so.
I am so glad to have found this site! [Thanks Natgas!:)]
