Prevalence and clinical correlates of COVID-19 outbreak among health care workers in a tertiary level hospital in Delhi

In this study, we summarize the epidemiological characteristics of COVID-19 outbreak among Healthcare workers (HCWs) in a tertiary care hospital and compared various parameters and preventive measures taken by positive HCWs to a comparable cohort of COVID negative HCWs. 52.1% of COVID-19 positive HCWs showed symptoms of which only three needed hospitalization possibly due to a younger cohort of HCWs who got infected (35.9 ± 9.3 years). Findings of present study found some protective role of full course prophylactic hydroxychloroquine as compared to a control group (p=0.021) and use of N95 masks over others (p<0.001). Our results did not show any added protection with the use of prophylactic Vitamin C, D, Zinc, or betadine gargles. We also observed outbreak control with increased awareness, near universal testing, PPE provision, sanitization drive, and promoting social distancing among HCWs.
