HEPA filters of portable air cleaners as a tool for the surveillance of SARS-CoV-2

Studies about the identification of SARS-CoV-2 in indoor aerosols have been conducted in hospital patient rooms and to a lesser extent in nonhealthcare environments. In these studies, people were already infected with SARS-CoV-2. However, in the present study, we investigated the presence of SARS-Co...

description Studies about the identification of SARS-CoV-2 in indoor aerosols have been conducted in hospital patient rooms and to a lesser extent in nonhealthcare environments. In these studies, people were already infected with SARS-CoV-2. However, in the present study, we investigated the presence of SARS-CoV-2 in HEPA filters housed in portable air cleaners (PACs) located in places with apparently healthy people to prevent possible outbreaks. A method for detecting the presence of SARS-CoV-2 RNA in HEPA filters was developed and validated. The study was conducted for 13 weeks in three indoor environments: school, nursery, and a household of a social health center, all in Ciudad Real, Spain. The environmental monitoring of the presence of SARS-CoV-2 was conducted in HEPA filters and other surfaces of these indoor spaces for a selective screening in asymptomatic population groups. The objective was to limit outbreaks at an early stage. One HEPA filter tested positive in the social health center. After analysis by RT-PCR of SARS-CoV-2 in residents and healthcare workers, one worker tested positive. Therefore, this study provides direct evidence of virus-containing aerosols trapped in HEPA filters and the possibility of using these PACs for environmental monitoring of SARS-CoV-2 while they remove airborne aerosols and trap the virus.

En estos estudios, las personas ya estaban infectadas con SARS-CoV-2. Sin embargo, en el presente estudio investigamos la presencia de SARS-CoV-2 en filtros HEPA alojados en purificadores de aire portátiles (PAC) ubicados en lugares con personas aparentemente sanas para prevenir posibles brotes. Se desarrolló y validó un método para detectar la presencia de ARN del SARS-CoV-2 en filtros HEPA. El estudio se llevó a cabo durante 13 semanas en tres entornos interiores: escuela, guardería y una vivienda de un centro sociosanitario, todos en Ciudad Real, España. El monitoreo ambiental de la presencia de SARS-CoV-2 se realizó en filtros HEPA y otras superficies de estos espacios interiores para un tamizaje selectivo en grupos de población asintomáticos. El objetivo era limitar los brotes en una etapa temprana. Un filtro HEPA dio positivo en el centro sociosanitario. Después del análisis por RT-PCR de SARS-CoV-2 en residentes y trabajadores de la salud, un trabajador dio positivo. Por lo tanto, este estudio proporciona evidencia directa de aerosoles que contienen virus atrapados en filtros HEPA y la posibilidad de usar estos PAC para el monitoreo ambiental del SARS-CoV-2 mientras eliminan los aerosoles en el aire y atrapan el virus.
