Abstract Introduction SARS-CoV-2 infection in some cases is complicated by clinical sequelae known as post-Covid syndrome (PCS). Given the lack of a shared nosographic criterion, it is important to know the distribution of clinical pictures and the relationship of PCS with occupational factors. Methods PCS symptoms were collected during health surveillance in the workplace. Stress was studied with the effort/reward imbalance model. Work ability was measured with the Work Ability Index, sleep was studied with the Pittsburgh Sleep Quality Inventory, and mental health with Goldberg’s anxiety and depression scales. The distribution of symptoms was studied by cluster analysis. Results In a population of 1378 workers under health surveillance, 164 COVID-19 cases occurred by 2021 and 115 of them (70%) had PCS. Three main clinical pictures were recognized: anosmia/dysgeusia (41% of cases); weakness/tiredness/fatigability (38%); and complex pictures including, in addition to the previous ones, muscle aches, headache, insomnia, dyspnea, tachycardia, and neuropsychological disorders (21%). PCS cases had a significant reduction in work capacity compared with colleagues healed without relics (p0,05). The occurrence of PCS was significantly associated with poor sleep quality (p0.05), anxiety (p0.01) and depression (p0.01). Work-related stress was not significantly associated with PCS. Discussion Although less severe than observed in severe cases of COVID-19 admitted to intensive care unit, PCS in a significant proportion of previously healthy workers may require supportive interventions to regain full work capacity. Conclusion Recognizing PCS in workplaces is very important to put in place the necessary measures to protect workers and limit the impact on productivity and health.
