Luz ultravioleta C: una alternativa eficiente contra la pandemia

Jorge Homero Wilches Visba, Juan José Bandera Barros, Jorge Camilo Méndez Hernández

Resumen


La pandemia por COVID-19 ha generado un impacto negativo en los sistemas de salud y la economía mundial. El agente etiológico de la COVID-19, el SARS-CoV2, puede permanecer de horas a días en superficies y aerosoles, representando un desafío en la descontaminación de objetos y ambientes cerrados. Agentes químicos como el alcohol, peróxido de hidrógeno, hipoclorito de sodio se han empleado con éxito para erradicar al coronavirus de superficies. Dado que estos agentes pueden causar daños en elementos de protección personal (como las máscaras), son irritantes y no parecen ser efectivos para la descontaminación de aerosoles, la luz ultravioleta ha sido explorada como una medida de mitigación para el desconfinamiento seguro. En este trabajo se realiza una revisión acerca de los principios físicos de la irradiación con luz ultravioleta y su interacción con la materia biológica. También se esboza un esquema de irradiación que podría ser útil para eliminar al SARS-CoV2 de superficies y aerosoles en ambientes cerrados.

Palabras clave


ultravioleta; COVID-19, influencia, exposición, irradiación, SARS-CoV2.
