| Abstract: | "OBJECTIVES: To evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread inside the healthcare setting using environmental sampling and indoor air quality (IAQ) parameters. METHODS: Ward/ICU rooms had IAQ parameters monitored in real-time, including volatile organic compounds and particulate matter. Surface and three air samples with different exposure times were collected in each room and tested for SARS-CoV-2 using quantitative Rt-PCR. Environmental sampling and IAQ data were compared to provide information about viral spread. RESULTS: SARS-CoV-2 RNA was detected in 6/10 rooms and 9/30 air samples, which is proportionally higher than previous studies. Sampling time confirmed to be crucial to viral detection. No correlations between IAQ parameters could be associated with positive/negative samples even when aerosol-generating procedures were performed. CONCLUSION: Environmental sampling of SARS-CoV-2 RNA may be used as an indicator of occupational safety. IAQ is also a potential tool but requires further research" |
