Some of the symptoms of long COVID-19:

– Fatigue

– Joint or chest pain

Description of the Study:

  • Title: Cocolate.
  • Principal Investigator: Olivier Robineau.
  • Centres of Implementation: It is coordinated by the Tourcoing hospital centre and the idea is to gradually extend the study to at least 20 hospitals.
  • Study population: It aims to reach 1000 patients from all over France who have not experienced a very severe form of Covid-19 and have not been hospitalised in intensive care. However, they will need to have experienced at least one persistent symptom two months after the acute episode of the disease.
  • Type of study: Observational.
  • Design: Patients will be referred by their general practitioners to the hospitals, who will offer them a coordinated pathway to explore their symptoms and may include them in the study.

Objectives of the Study:

Principal Objectives:
(1) To understand long COVID-19 and define which symptoms can actually be associated with it.
(2) To identify the causes of the persistence of symptoms in some patients, sometimes months after the acute phase of COVID-19 disease.
