The risk of infection by biological agents is recognized as one of the most important, especially in nursing professionals. Objective: To identify the perception of nursing personnel on biological risk, in the Vicente Corral Moscoso Hospital, Cuenca-Ecuador. Methodology: Cross-sectional, descriptive observational research with a quantitative approach. The sample was 164 nurses. A questionnaire validated in Cuba was used for data collection, and the processing and analysis of the results was carried out in the SPSS v25 programme. Results: 59% were between 20 and 30 years old, 92% were female, 50% were single and 44% were nursing professionals. In relation to the individual, 60% have received little training on biological risk, 59% have received protective measures. In the nature of the risks, 92% do consider the consequences of biological risks, 79% report little information on accidents and incidents in the institution. In risk management, 68 per cent report that few managers and supervisors are aware of current biosecurity resolutions. Conclusion: Nurses have received little biohazard training, are unaware of some of the protective measures and accidents and incidents in the facility.
