Borrelia burgdorferi and Borrelia mayonii are the most common causes of Lyme disease in the United States, while Borrelia afzelii and Borrelia garinii are the most common causes of Lyme disease transmission in Europe and Asia. People who spend a lot of time in grassy and densely wooded regions are more likely to have Lyme disease, according to Trillium Health Solutions, because black-legged ticks are mostly found in these locations. https://trilliumhealthsolutions.blogspot.com/2021/09/lyme-disease-symptoms-diagnosis-treat.html
