Prevalence, duration, and factors influencing post-COVID conditions among patients at several public hospitals, Alexandria governorate, Egypt 2022–2023
Abstract
Background: Post-COVID conditions (PCC), characterized by persistent symptoms following acute infection, represent an emerging chronic illness that potentially affects millions of people worldwide. SARS-CoV-2 infection has resulted in a PCC incidence ranging from 10 to 30 % in non-hospitalized individuals to 50–70 % in hospitalized patients. Most PCC patients experience mild symptoms, while a minority report severe manifestations. We aimed to estimate the prevalence of PCC among COVID-19 patients who attended three public hospitals in Alexandria, Egypt between June 2022 and February 2023, and to investigate its risk factors. Methods: All COVID-19-confirmed patients aged >18 years attended the selected hospitals, and their household contacts were contacted. Data were collected through telephone interviews using a questionnaire adapted from World Health Organization (WHO) and Penn Medicine tools, covering demographics, COVID-19 history, and PCC symptoms. PCC was defined as symptoms starting three months after the post-acute infection and lasting for at least two months beyond. Statistical analyses employed descriptive statistics, chi-square tests, and a logistic regression model, with a significance level of p < 0.05. Results: A total of 1546 patients were enrolled. Their mean age was 39.7 ± 15.9 years, 46.0 % were males, and 13.9 % had comorbidities. Of them, 760 patients (49.2 %) reported PCC symptoms including, 52.6 % seen at outpatients, 26.7 % were admitted, and 0.5 % required admission to ICU. PCC symptoms included shortness of breath (94.2 %), mood changes (13.9 %), cough (13.0 %), and fatigue (8.8 %). PCC was associated with older age, hospitalization during acute COVID-19, comorbidities including asthma, hypertension, and diabetes, as well as treatment with different COVID-19 medications. Logistic regression shows that asthma, male gender, and treatment with medicines at the hospital remained significant in the model (ORs: 6.85, 0.36, and 0.88, p < 0.001). Conclusion: This study sheds light on PCC's prevalence and influencing factors following infection in Alexandria, Egypt. Common PCC symptoms included difficulty in breathing, fatigue, and psychological manifestations. The findings emphasize the critical need for early intervention and targeted management strategies, especially for high-risk groups such as asthma patients, to alleviate the long-term health consequences of COVID-19. Study results could guide the prevention of PCC e.g., through vaccination, management of long-term sequelae of PCC e.g., rehabilitation, and psychological support initiatives.
