To identify the presence of viruses in dust samples collected from various public spaces.
Key Findings:
Identified viruses include SARS-CoV-2, influenza A, RSV, norovirus, adenovirus, Epstein-Barr virus, and multiple rhinoviruses.
Rhinoviruses were detected in 85% of samples.
Child-focused buildings exhibited different viral profiles compared to adult spaces, with higher detection of specific polyomaviruses and cytomegalovirus.
Sequencing results showed correlation with qPCR testing for SARS-CoV-2 and influenza A.
Interpretation:
The study indicates that vacuum dust can serve as a noninvasive method for monitoring viral circulation in buildings, which may enhance public health surveillance efforts.
Limitations:
The method identifies viral genetic material rather than live infectious viruses, which limits its applicability.
The study does not determine the source of the detected viruses.
Conclusion:
Dust samples may provide critical insights into viral presence in public spaces, underscoring the necessity for further research in environmental virology.
Amoxicillin-clavulanate was not linked to lower treatment failure but was associated with a slightly higher risk of secondary infections compared with amoxicillin in adults with uncomplicated acute sinusitis.
