Covid-19 has become a public health issue since its discovery in China in 2019. This pandemic has had significant consequences on the physical, mental and social health of affected individuals. The aim of this research was to determine the impact of coronavirus infection on the Algerian population through a retrospective descriptive survey, and to identify the organic and psychosocial sequelae caused by the infection, known as Covid long. The results showed that half of the respondents (52%) had symptoms of Covid long, including a variety of symptoms, the most frequent of which were joint pain (72%), fatigue (70%), diabetes (67%), dyspnoea (52%), arterial hypertension (44%) and arrhythmia (37%). Anxiety was the most marked psychological symptom, followed by depression. Although recourse to hospitalization is rare, these prolonged forms will have a major social impact, necessitating the implementation of appropriate preventive and public measures.
