RESUMO
Introducción: Al inicio de la pandemia de COVID-19, las empresas mineras, debieron implementar sistemas de gestión para prevenir transmisión de SARS-CoV-2. Objetivo: Describir los resultados iniciales de la estrategia multimodal para la prevención de COVID-19, en una faena minera. Materiales y Métodos: Estudio descriptivo, de corte transversal. Se estructuró un sistema de gestión que consideró medidas administrativas, ambientales, tamizaje de riesgos y gestión de casos de riesgo al interior de la empresa. Análisis de datos con estadística descriptiva. Resultados: Las medidas administrativas se tradujeron en que 8.116 (34%) trabajadores de la faena fueron suspendidos de sus labores habituales. El tamizaje de riesgo antes del ingreso a la faena identificó 450 casos sospechosos que fueron derivados a su domicilio. En el procedimiento de gestión de casos 1.073 personas fueron clasificadas en algunos de los grupos de riesgo. Se detectaron 10 casos de trabajadores con RPC positiva, siendo que 50% fue asintomático; en los sintomáticos, los síntomas más frecuentes fueron: tos (60%) y cefalea (40%). Conclusiones: Estos resultados, dan luces sobre la importancia de implementar una estrategia multimodal, adaptada a la realidad local de una empresa de la gran minería, para prevenir la transmisión de SARS-CoV-2.
Background: Mining companies must implement management systems dedicated to health and safety at work to prevent the transmission of SARS-CoV-2 among their workers, however, the literature on this is scarce. Aim: To describe a multimodal strategy for the management of health and safety at work, to address the risk of COVID-19 in large mining. Methods: Descriptive cross-sectional study, carried out in a large mining company. A management system was structured that considered administrative measures, of an environmental nature, risk screening, and management of risk cases within the company. The data analysis was done using descriptive statistics. Results: The administrative measures resulted in 8,116 (34%) workers at the site being suspended from their usual work. Risk screening before entering the site identified 450 suspected cases that were referred to their home. In the case management procedure, 1,073 people were classified in some of the risk groups. 10 cases of workers with PCR were detected in the follow-up period. Environmental measures were not very sensitive. Conclusions: These results shed light on the importance of implementing a multimodal strategy, adapted to the local reality, in preventing the spread of SARS-CoV-2 in the period under study, at the mining site intervened.
