Introduction: The lockdown was implemented nationally for six weeks, followed by another two weeks of graded lockdown in districts in India as a means to prevent spread of infection. During this period, there was restriction of movement of residents except for those engaged in providing essential services.
Aim: To find out socio-demographic profile of patients along with the impact of lockdown and spread of Coronavirus-19 (COVID-19) infection post-lockdown.
Materials and Methods: A prospective observational study conducted in Bairagarh, a suburban area of Bhopal. The study was conducted for three months i.e. from 9th April 2020 to 9th July 2020. A contact tracing questionnaire was used for data collection. The data was collected by actual visiting the patientâ€™s address. The data collected was compiled and analysed using Microsoft Excel 2020. The patients were instructed to inform the data collector of any post-viral symptoms after 15 days of diagnosis to find out any post-viral complaints. Percentages and proportions were derived using Epi info-7.0.
Results: During the study period of three months, in total 90 patients were interviewed. Almost 85.5% cases were found post-lockdown. Most common age group to be involved was 31-45 years. Males were more commonly infected. Only 14.44% patients who worked during lockdown were infected. Almost 26.6% patients were involved in cloth merchandise business which was closed during lockdown and had a sudden upsurge in business during unlock. In total 47.7% patients were asymptomatic when tested. Relative Risk (RR) of acquiring infection post-lockdown was 1.13. Doubling rate of infection among study population during lockdown was found to be 14.05 days compared to 5.35 days post-lockdown. Almost 80% patients did not have any postviral symptoms. The most common symptom seen was nose block.
Conclusion: The lockdown was found to be effective strategy in controlling spread of COVID-19 infection as post-lockdown there was sudden increase in number positive cases.
