“Chronic” Lyme disease is a fertile hunting ground for quacks in the US, and increasingly elsewhere. It has been extensively studied, and there is no credible evidence to support it. That doesn’t stop people from claiming it as the cause of a variety of conditions including – naturally! – autism, and pursuing quack treatments, the most common of which are long-term antibiotics.
Self-diagnosed “sufferers” circulate details of “Lyme-literate” doctors who will prescribe these treatments. And in some places they cannot be stopped, because they successfully lobbied for legal protection.
All this is apparently fine, because it’s alternative.
