<dim:field element="description" qualifier="abstract" language="es-ES" mdschema="dc">La sala donde se admitieron los pacientes con síntomas leves tenía una mayor ocupación, tránsito de personas&#13;
en el pasillo y niveles de CO2, pero no hubo diferencias significativas en la detección de SARS-CoV&#13;
2 entre las salas. La concentración media de CO2 en las muestras positivas fue de&#13;
&#13;
569 ± 35,6 ppm. Considerando todas las muestras, los niveles de CO2 en el pasillo se correlacionaron positivamente&#13;
con las aperturas de las puertas de los pacientes, pero inversamente con los niveles de SARS-CoV-2. En&#13;
conclusión, el SARS-CoV-2 en el aire puede detectarse en interiores con una ventilación óptima, y ​​sus&#13;
niveles no se correlacionan con la concentración de CO2 en los pasillos del hospital. Por lo tanto, la evaluación de CO2&#13;
no debe interpretarse como un indicador de la presencia viral en el aire en todos los espacios interiores.</dim:field>
<dim:field element="description" qualifier="abstract" language="en-GB" mdschema="dc">Indoors, the infection risk of diseases transmitted through the airborne route is estimated&#13;
 from indoor carbon dioxide (CO2) levels. However, the approaches to assess this risk do not&#13;
 account for the airborne concentration of pathogens, among other limitations. In this study,&#13;
 we analyzed the relationship between airborne SARS-CoV-2 levels and environmental&#13;
 parameters. Bioaerosols were sampled (n = 40) in hospital corridors of two wards differing&#13;
 in the COVID-19 severity of the admitted patients. SARS-CoV-2 levels were quantified&#13;
 using droplet digital PCR. SARS-CoV-2 was detected in 60% of the total air samples. The ward where the mildly ill patients were admitted had a higher occupancy, transit of people&#13;
 in the corridor, and CO2 levels, but there were no significant differences in SARS-CoV&#13;
2 detection between wards. The mean CO2 concentration in the positive samples was&#13;
 569 ± 35.6 ppm. Considering all samples, the CO2 levels in the corridor were positively&#13;
 correlated with patient door openings but inversely correlated with SARS-CoV-2 levels. In&#13;
 conclusion, airborne SARS-CoV-2 can be detected indoors with optimal ventilation, and its&#13;
 levels do not scale with CO2 concentration in hospital corridors. Therefore, CO2 assessment&#13;
 should not be interpreted as a surrogate of airborne viral presence in all indoor spaces.</dim:field>
