Post COVID-19 clinical manifestations and its risk factors among patients in a Northern District in Kerala, India.

Background: The novel virus SARS-CoV-2 has caused a pandemic of coronavirus disease 2019 (COVID-19). There is emerging evidence of post-COVID-19 manifestations among patients who sustain acute COVID-19. Most studies report fatigue, dyspnea, and myalgia as the common symptoms; however, currently, there is limited knowledge of these post-COVID manifestations and their risk factors, especially in India. Methods: A descriptive cross-sectional study was conducted among patients who had attended the district post-COVID clinic, Wayanad district, Kerala, from October 2020 to June 2021. Data were collected by direct/telephonic patient interviews and from their existing case records, using a pretested semi-structured proforma. Results: The sample size was 667. The mean age of the study population was 45 years (standard deviation [SD]: 14.55). The majority of the population presented with dyspnea (48%), fatigue (32%), and cough (25.6%). Mental health problems were also reported in 6% of participants. The respiratory system was commonly involved (61.2%). Around one-third of the patients (36.4%) had dyspnea on exertion and 11.8% had dyspnea at rest. One-fifth of the population reported aggravation of pre-existing co-morbidity and half of the respondents had persistence of at least one symptom after 6 months. There exist statistically significant associations between identified risk factors, especially gender, increasing age, the severity of COVID-19 infection, history of tobacco/alcohol use, and co-morbidities with outcomes. Conclusion: As post-COVID syndrome is a multisystem disease, integrated rehabilitation is required with targeted intervention for survivors based on their symptoms and needs.
