<unk>  (CLD) is the name used by some people with "a broad array of illnesses or symptom complexes for which there is no reproducible or convincing scientific evidence of any relationship to Borrelia burgdorferi infection" to describe their condition and their beliefs about its cause. Both the label and the belief that these people's symptoms are caused by this particular infection are generally rejected by medical professionals, and the promotion of<unk>  is an example of health fraud.<unk>  in this context should not be confused with genuine<unk><unk> , a known medical disorder caused by infection with Borrelia burgdorferi, or with post-treatment<unk><unk>  syndrome, a set of lingering symptoms which may persist after successful treatment of infection with<unk>  bacteria. Despite numerous studies, there is no evidence that symptoms associated with CLD are caused by any persistent infection. The symptoms attributed to<unk> <unk>  are generic and non-specific symptoms, such as fatigue and muscle pain, and in many cases are likely due to fibromyalgia or<unk>  fatigue syndrome. Fibromyalgia can be triggered by an infection, and antibiotics are not a safe or effective treatment for post-infectious fibromyalgia. A number of alternative health products are promoted for<unk> , of which possibly the most controversial and harmful is long-term antibiotic therapy, particularly intravenous antibiotics. Recognised authorities advise against long-term antibiotic treatment for<unk><unk> , even where some symptoms persist post-treatment. Following disciplinary proceedings by state medical licensing boards in the United States, a subculture of "Lyme literate" physicians has successfully lobbied for specific legal protections, exempting them from the standard of care and science-based treatment guidelines. Such legislation has been criticised as an example of "legislative alchemy", the process whereby pseudomedicine is legislated into practice.
