Background and Objectives:The present study aimed to determine the prevalence of post-traumatic stress disorder (PTSD) and its related factors in the survivors of Covid-19. Materials and Methods:In this descriptive study 413 patients who had a history of hospitalization due to covid-19 disease were selected using the convenience sampling method. Data were collected using a questionnaire and analyzed by binary logistic regression.Results: Out of 402 participants, 148 participants (36.8%) had PTSD. In addition, suffering from coronary heart disease (OR=1.80, p<0.001) and adverse mental health status (OR=1.21, p<0.001) increased the odds ratio of PTSD by 80% and 21%, respectively. Conclusion:This study showed that more than one-third of the survivors of Covid-19 have PTSD. Therefore, it is recommended mental health status screening be integrated into the discharge plans of these patients.
