Quarantine for suspected patients of being infected by the COVID-19 can lead to negative consequences for mental health and the appearance of depressive symptoms.

To assess the prevalence of depression in quarantined patients, and to analyze the associated factors.

This was a descriptive and analytical survey, carried out from April 4 to May 30, 2020, with 149 patients consulting the COVID-19 sorting box at the Hedi Chaker CHU in Sfax. Suspected COVID-19 patients were contacted by phone during their quarantine and invited to participate in our study. The Patient Health Questionnaire (PHQ-9) scale was used to assess the severity of depression. Cutoffs of 5, 10, 15, and 20 represent minimal, mild, moderate, moderately severe, and severe levels of depression based on PHQ-9 scores. A cutoff score of 10 determines major depression.

The results showed a prevalence of major depression of 10.7%. Of all patients, 89.3% had minimal to mild depression; 10% had moderate to moderately severe depression and 0.7% had severe depression. The PHQ-9 score was statistically correlated with travel to a suspect area during the 14 days preceding the consultation (p = 0.008), contact with a subject confirmed COVID-19 (p = 0.01), previous follow-up in psychiatry (p = 0.047), the change of residence during quarantine (p = 0.045), the fear of transmitting the disease to relatives (p = 0.00) and the positive result of the nasopharyngeal swab (p = 0.00).

Psychological distress was felt in our patients. We recommend that necessary measures should be taken to combat depression.
