Abstract

Introduction: COVID-19 is a pandemic with a clinical spectrum ranging from mild to moderate respiratory infection to a fatal illness. Elucidating the epidemiology of such disease is important to understand and characterize its potential impact. Methods: This study is an epidemiological analysis of confirmed COVID-19 cases in Karnataka from 9th March to 7th June 2020 and aims to study patterns of the disease to provide useful analysis for measures that can be taken in the future. Results: The study concluded that young men were most infected while the mortality was higher among the elderly (Case fatality rate of 12.3% in patients for more than 60 years). The total case fatality rate of the state (1.11%) was lesser compared to the national rates (2.81%). In the zonal colour coding of the districts, the state capital was a hotspot and had the highest number of cases in the state until 1st June. After the first week of the lifting of the lockdown, the Udupi district recorded the highest number of cases. An increase in the number of cases in the state in the first week of June, can be attributed to the influx of passengers from other states. Conclusion: Regulation of activities involving crowd gathering and movement and active surveillance and contact tracing by the Government of Karnataka contained the spread of the virus to some extent in the state and had lower case fatality rates and deaths per 10 million, compared to national averages. Identification of risk factors operating in the hotspot areas and recognizing the health promotion factors that benefitted the recovered cases can help the government to plan strategies to overpower the evolving epidemic.
