Summary

This study looks at people who still feel sick after being treated for Lyme disease. Researchers want to find out if the Lyme bacteria are still alive in the body and causing these ongoing symptoms. Up to 700 participants, including those with chronic Lyme, recovered patients, and healthy volunteers, will undergo blood tests, spinal taps, and brain scans. The goal is to better understand the condition and develop better diagnostic tests.
