Popis: Introduction: India has experienced many phases of the rise and fall of Coronavirus Disease-2019 (COVID-19) cases from the first quarter of 2020 to the present date. It is important to periodically assess the clinicoepidemiology and local factors affecting the pandemic in each geographical area. Emerging Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variants {Variants of Concern (VOC) and Variants of Interest (VOI)} are contributing to ongoing unprecedented outbreaks, posing new challenges. Continuous surveillance is essential to keep track of currently circulating lineages. Aim: To study the clinicoepidemiological trends of COVID-19 disease in patients. Materials and Methods: A cross-sectional descriptive study was conducted on 53,311 suspected COVID-19 patients attending Jaipur National University of Medical Sciences and Research (JNUIMSRC), Jaipur, Rajasthan, India. Socio-demographic variables, clinical signs and symptoms, details of hospitalisation, and mortality data were collected between May 2020 and April 2022. All patients with Influenza-like illness and suspected COVID-19 were included in the study. Ribonucleic Acid (RNA) extraction and Polymerase Chain Reaction (PCR) were performed using Indian Council of Medical Research (ICMR) approved kits. Mean, median, and “p-values” were calculated using Microsoft Excel and Statistical Package for Social Sciences (SPSS) version 21.0 software. Results: A total of 15.77% (8410/53,311) of patients tested positive for SARS-CoV-2 by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The median age of the patient population was 43±18.44 years, with a male-to-female ratio of 1.86, 33.21% (2793/8410) of patients were asymptomatic. Cough (56.74%; 4772/8410) was the most common symptom, followed by fever (56.48%; 4750/8410) and sore throat (50.31%; 4231/8410). The surge in the number of COVID-19 positive cases varied month-wise during the study period. The case fatality rate was 3.19%. Conclusion: Asymptomatic cases have contributed to the widespread distribution of COVID-19 disease. Periodic remodeling of testing and mitigation strategies is required, given the early detection of asymptomatic infections in co-morbid and elderly patients for the management of the COVID-19 pandemic.
