We are on the sixth floor of the Clinique du parc, in Castelnau-le-Lez (Hérault), in the suburbs of Montpellier. The private site is located in a bucolic and upscale area, among trees and along the Lez river. Here, patients parade every week who suspect they are suffering from long Covid. Symptoms, which could be explained by the persistence of viruses in the body, linger for months and sometimes years after infection with SARS-CoV-2. Claudine arrived the same morning, this Thursday, November 7. Like around a hundred people this year, she will hold consultations throughout the day.
