Severe and sometimes irreversible sequelae are observed in people who have developed asevere form of COVID-19 (pulmonary, cardiovascular, renal, neurological sequelae amongothers). More than 10% of individuals who contracted the disease, even in a mild form,still have at least one of the initial symptoms at six months, also known as prolongedsymptoms or long COVID syndrome. The most frequently observed symptoms are asthenia,neurological disorders (headache, anosmia, ageusia, etc.), cardio-thoracic disorders,pain, digestive or skin disorders. Very recently, the first results of a Britishprospective cohort study (PHOSPCovid) indicate that more than half of the COVID-19survivors who were hospitalised experienced a very severe to moderate deterioration intheir mental and/or physical health five months after hospitalisation. Women areparticularly affected. Another American study shows that 85% of non-hospitalised COVID-19patients developed at least 4 neurological symptoms impacting their quality of life. Themost common are: "brain fog" (81%), headaches (68%), numbness or tingling (60%), tasteimpairment (59%) and loss of smell (55%).These disabling symptoms may persist for weeks or months, deteriorating the quality oflife of patients and making it difficult for some to return to a normal life. On thebasis of current knowledge concerning the long-term sequelae of SARS-CoV-2 infection, itseems necessary to offer these subjects a specific care pathway and to adapt their livingand working conditions beyond their medical care.The present study is aimed at measuring the impact of long COVID on the health andquality of life of the defence community (military personnel and their families).
