    Snippet: Objective: To evaluate the occupational safety and health management of COVID-19 at a company in the Peruvian fishing sector Methods: The independent variable was occupational safety and health management, defined as the implementation of preventive and control measures in response to COVID-19. The dependent variable was defined as the number of detected COVID-19 cases and test positivity rate. We used a pre-(implementation phase) and post-test (following the implementation phase) study design.
    Document: Objective: To evaluate the occupational safety and health management of COVID-19 at a company in the Peruvian fishing sector Methods: The independent variable was occupational safety and health management, defined as the implementation of preventive and control measures in response to COVID-19. The dependent variable was defined as the number of detected COVID-19 cases and test positivity rate. We used a pre-(implementation phase) and post-test (following the implementation phase) study design. We performed a non-parametric inferential analysis to identify any significant pre-and post-test differences and any associations between the variables. Results: The company initiated a strategy to detect positive cases through the use of serological tests. During the first stage, 2329 tests were conducted, yielding a positivity rate of 71%. Once prevention and control actions were implemented, the positivity rate in August 2020 had decreased to 15.65%,, a statistically significant decrease (p<0.05), as well as its relationship to the measures implemented. Conclusions: This occupational safety and health intervention significantly reduced the number of COVID-19 cases and positivity rate in this group of workers in the Peruvian fishing sector.

La variable dependiente se midió a través del número de casos detectados y la tasa de positividad de Covid-19. Se utilizó un diseño preexperimental con una preprueba, durante la implementación en proceso y una post prueba, con información recopilada al finalizar las acciones preventivas y de control. Se realizó un análisis inferencial no paramétrico para establecer diferencias significativas entre la preprueba y la post prueba y el grado de asociación entre las variables. Resultados: La empresa inició una estrategia de detección de casos positivos a través del uso de pruebas serológicas. Durante la primera etapa, se realizaron 2329 pruebas que arrojaron un 71% de positividad. Una vez que se implementaron las acciones de prevención y control la tasa de positividad se redujo a un 15.65% durante agosto del 2020. Las pruebas inferenciales mostraron un nivel de significación (p<0.05) en la reducción obtenida, así como en la relación de esta con las medidas adoptadas. Conclusiones: Una adecuada gestión de seguridad y salud en el trabajo frente al Covid-19 redujo de manera significativa el número de casos detectados y la tasa de positividad del Covid-19 en trabajadores del sector pesquero peruano.
