Episode notes
Lyme Disease Spread Became A National Problem
- Josh Clark says Lyme disease has spread far beyond its old Northeastern niche and now appears in all 48 contiguous states.
- He calls it the top U.S. vector-borne disease, with high-risk counties reaching about half the country.
Why The Lyme Bacterium Is So Hard To Defeat
- Borrelia burgdorferi excels at infecting humans by moving through blood, grabbing vessel walls, and exiting into tissues.
- Josh Clark says it also changes protein expression unusually fast, helping it evade antibodies before the immune system catches up.
The Bullseye Rash Misses Too Many Cases
- The classic bullseye rash is a strong Lyme clue, but it appears in only about 70 to 80 percent of cases.
- That leaves many patients with vague flu-like symptoms, headaches, weakness, and joint pain that get missed or misdiagnosed.
