Abstract
Context: Health-care workers (HCWs), being the front-line warriors, have been at increased risk for COVID-19 throughout the pandemic. However, the current extent of SARS-CoV-2 transmission and associated risk factors is still unclear in low- and middle-income countries, like India, especially in the department of obstetrics and gynaecology, which propelled this study. Aims: (i) Frequency of infection among HCWs among OBGYN department and cycle threshold value (Ctv) of SARS-COV-2 on RT-PCR. (ii) Clinical presentation, assessment of risk factors, and its impact on HCWs. Settings and Design: This was a prospective study conducted at the Department of Obstetrics and Gynaecology, VMMC and Safdarjung Hospital, New Delhi for the duration of 6 months. Methods and Material: All SARS-CoV-2-positive HCWs in the department were interviewed verbatim after recovery, through a self-formulated, validated questionnaire, and answers recorded on pre-designed proforma. Statistical Analysis Used: Categorical variables were presented as number and percentage (%), whereas continuous variables as mean ± standard deviation (SD) and median values. Data were transferred on Microsoft Excel spreadsheet and analysed using SPSS v 27.0.Entities:
