    AbstractThe present study describes the epidemiological characteristics of 3,08,259 suspected cases of COVID-19 from the Pune district, India. The samples were referred for COVID-19 testing between January 24, 2020 and April 30, 2021. Demographic and clinical data were extracted from the ICMR-portal as a single dataset and analyzed. Of the 3,08,259 samples tested, 2,63,833 (85.6%) were asymptomatic. Symptomatic cases ratio in the first and the second COVID-19 wave was 1:2. Among symptomatic cases, cough was the most common complaint, followed by fever. Among the COVID-19 positives, one-fifth were asymptomatic, highlighting the necessity for close contact tracing even among apparently healthy contacts. The second wave of COVID-19 had double the per cent of symptomatic individuals as compared to the first wave.
