http://www.ncbi.nlm.nih.gov/pubmed/26094509 Wow, you know something is wrong when the Chinese government are leading the way in terms of openness and honesty... I had to check (even though I used to live there!) how many provinces there were...there are 23, counting Taiwan, which I sure wasn't involved in this study. So 21 out of 22 provinces have endemic levels of Lyme (plus Taiwan, as has already been documented). I think this is a significant finding for other countries too, since China is the size of Western Europe and contains many different climatic zones. The fact that Lyme was actually more common in the south shows that the old story about Lyme being a disease of the temperate zones is completely wrong. Since it must have been found in either Yunnan or Hainan (assuming I'm right about Taiwan) it has now been shown to exist in a tropical zone, as well as the sub-tropical zone just to the north.
