In April 2020, a meta-analysis on the long-term sequelae of respiratory syndromes related to seasonal coronaviruses (SARS and MERS) showed a significant alteration in quality of life, with in particular a decrease in physical and emotional capacities and a deterioration of social life. An improvement of the quality of life is evidenced after 6 months but without reaching the level usually observed in healthy people. The impact of SARS-CoV-2 infection on quality of life can be explained by the persistence of pleomorphic symptoms in the medium to long term. In the military population, the majority of SARS-CoV-2 cases present minor to moderate forms of the disease. Military personnel have living conditions that differ from those of the general population, in particular because of their geographic mobility, which may be responsible for isolation from the family. This isolation can be regular (we speak of "geographical celibacy" when the soldier is posted in a geographical area far from the family unit) and/or occasional, during missions on the national territory or outside. This singularity justifies a study on the impact of SARS-CoV-2 (COVID-19) infection on the quality of life in this specific population.

Inclusion Criteria:

• Military personnel
• COVID+: diagnosed with COVID-19 and managed in ambulatory care since March 14th, 2020
• COVID-: not having been infected with SARS-CoV-2

Exclusion Criteria:

• Hospitalized for COVID-19
• Having received a treatment against COVID-19 (other than paracetamol)

The study population is composed of military staff followed at the 1st Centre Médical des Armées (Paris, France) who have suffered from COVID-19 and were managed in ambulatory care (COVID+ group) and who have not been infected by SARS-CoV-2 (COVID- group).
