Ive seen Dr Klemann in Germany which is supposed to be top 3 LLMDs in Europe and he said I had Lyme and co infections.
(I have zero aversions to ticks- I owned dogs ....You remove the tick. I have a phD in: Tick Removal. (counter clockwise, twist, I never lose the head). So then they are all over you.
A bit complex- our western fence lizard is an alternative host and the spirochete is killed in the ticks if they fedd on western fence lizards.
We have a bit lower rate of it here, as a result. (this lizard is also missing from Seattle Washington, so No, it won't like Norway).
But the story is complicated...
