• A multicenter study presented the prevalence data and associated risk factors of post-COVID cough one year after hospital discharge among COVID-19 survivors.
• The study included patients who had recovered from COVID-19 at three public hospitals in Madrid, Spain. All the patients were scheduled for a telephonic interview.
• Patients were enquired about respiratory symptoms, including fatigue, dyspnea, chest pain, and cough after discharge from the hospital.
• Researchers obtained the clinical and hospitalization data from hospital records. 

Findings from the study - 

• A total of 1,950 patients were assessed at 11.2 months following hospital discharge.
• Only 367 of these (18.8%) were completely free of any respiratory post-COVID symptom.
• The prevalence of long-term cough, chest pain, dyspnea, and fatigue was 2.5%, 6.5%, 23.3%, and 61.2%, respectively (Fig.).
• Clinical and hospitalization factors did not appear to be associated with long-term post-COVID cough. 

To conclude -

• The prevalence of post-COVID cough a year after infection was found to be 2.5% in individuals who survived hospitalization.
• There were no apparent risk factors tied to long-term post-COVID cough.
