Dr. Ronan Glynn:

It is important to put the WHO's international classification of diseases, ICD, language in context. The WHO did not produce guidance but a list of categories of Lyme disease. It is essentially a dictionary. It is very important to distinguish between it and clinical guidance which is used in clinical practice. The WHO has stated that, just because a particular entity is included in or excluded from the dictionary, it is not a judgment on whether a condition is valid or that a particular treatment works. It should not be seen as an indication of efficacy or a validation of a particular condition.
