Post-COVID Syndrome and Severity of COVID-19: A Cross-Sectional Epidemiological Evaluation From North India

Abstract

BackgroundCOVID-19 has now lasted for more than two years as a pandemic and has had enduring effects on the health of people as the post-COVID syndrome. Recent literature has shown the long-term effects of COVID‐19 on various organ systems, including but not limited to respiratory, cardiovascular, neurological, musculoskeletal, and gastrointestinal systems.Methods and objectivesWe aimed to estimate the prevalence of post-acute COVID symptoms in a tertiary care center in northern India; observe the effects of the demographic profile of age, BMI, gender, and presence of comorbidities on the persistence of post-COVID syndrome, and explore any correlation between the severity of COVID-19 disease and the persistence of post-COVID symptoms. We designed a survey containing structured questions evaluating post-COVID symptoms beyond three weeks (post-acute COVID phase), six weeks (post-COVID phase), and 12 weeks of acute illness. It was administered online. ResultsPrevalence of post-COVID symptoms both after three and six weeks was reported to be 16.67% and 7.37%, respectively. The most common symptoms to persist were musculoskeletal symptoms (fatigue), followed by upper respiratory symptoms. Disease severity (p<0.05), BMI (p<0.05), and comorbidities were seen to affect post-COVID symptoms significantly, whereas gender and age of the patient had no significant effect. Disease severity significantly affected the persistence of post-COVID symptoms up to 12 weeks; however, this effect does not hold true in long COVID haulers. Also, the risk of developing persistent post-acute COVID symptoms was more in moderate to severe disease than in mild disease.ConclusionThe pandemic might be close to over, but it is not out of our lives yet, and the persistence of post-COVID symptoms is exigent.
