Introduction: Healthcare workers (HCWs) are at increased risk of acquiring the COVID-19 disease, if there is a breach in the personal protection while managing patients.
Objectives: 1. To estimate the pattern of risk exposure among healthcare workers exposed to confirmed cases of COVID-19 working in non-COVID zones of a Teaching Hospital, North-East India. 2. To determine the association between pattern of exposure with their COVID-19 status.
Materials and method: This was a hospital-based cross-sectional study conducted among all HCWs who had occupational exposure to laboratory confirmed COVID-19 cases between July and September 2020 in-non COVID zones of a major tertiary care hospital in Tripura.
Results: The present study showed that 215 HCWs were exposed to confirmed cases of COVID-19 while working in non-COVID zones of the hospital. Among the exposed, 39.5% of HCWs had high-risk exposure and 8.8% of HCWs were detected as COVID-19 positive. A majority of the study subjects experienced exposure in the hospital wards (66.0%), in surgical departments (19.5%), had close contact (less than one meter distance) with positive COVID-19 cases (73.5%), and had an exposure of more than 15 minutes (51.2%). The COVID status of the exposed HCWs was significantly associated with no source control (P = 0.016), close contact with COVID-19 positive cases (P = 0.026), more duration of exposure (P < 0.05), use of any PPE (P = 0.000). COVID status was also significantly associated with the high-risk exposure of the participants (P = 0.000).
Conclusion: Strict enforcement of the infection control measures like universal precautions should be practiced by HCWs to prevent hospital-acquired infections.
