    • Abstract:
      Background: Healthcare Workers (HCW) are repeatedly exposed to SARS-CoV-2 infection. The aim of this study was to identify factors associated with SARS-CoV-2 infection among HCW in one of the largest cities in Colombia.
      Methods: We conducted a case-control study, where cases had a positive reverse transcription-polymerase chain reaction and controls had a negative result. Participants were randomly selected and interviewed by phone. Analyses were performed using logistic regression models.
      Results: A total of 110 cases and 113 controls were included. Men (AdjOR 4.13 95% CI 1.70-10.05), Nurses (AdjOR 11.24 95% CI 1.05-119.63), not using a high-performance filtering mask (AdjOR 2.27 95% CI 1.02-5.05) and inadequate use of personal protective equipment (AdjOR 4.82 95% CI 1.18-19.65) were identified as risk factors. Conversely, graduate (AdjOR 0.06 95% CI 0.01-0.53) and postgraduate (AdjOR 0.05 95% CI 0.005-0.7) education, feeling scared or nervous (AdjOR 0.45 95% CI 0.22-0.91), not always wearing any gloves, caps and goggles/face shields (AdjOR 0.10 95% CI 0.02-0.41), and the use of high-performance filtering or a combination of fabric plus surgical mask (AdjOR 0.27 95% CI 0.09-0.80) outside the workplace were protective factors.
      Conclusion: This study highlights the protection provided by high-performance filtering masks or double masking among HCW. Modifiable and non-modifiable factors and the difficulty of wearing other protective equipment needs to be considered in designing, implementing and monitoring COVID-19 biosafety protocols for HCW.
