[Patient experience, epistemic authority and health challenges: the example of long COVID].

Since February 2020, hundreds of thousands of patients have been left with persistant symptoms after their infection. Along with their clinicians, these patients are exposed to a high degree of uncertainty and the urgent need to produce conceptual frameworks aimed at recognising, treating and validating their experience as patients suffering from new and protracted symptoms and witnessing debates as to how these symptoms should be qualified. In this respect, long covid illustrates the need to combine the collective experiential knowledge of patients and scientific knowledge for the benefit of the patients, clinicians and research.
