Air and Surface Contamination with SARS-CoV-2 in COVID-19 Admitting Wards in Shahrekord Hajar Hospital, Iran

Background and purpose: Coronavirus disease (COVID-19) is an infectious disease caused by severe acute respiratory syndrome (SARS-CoV-2). Rapid spread of the virus around the world shows that identification of transmission routes and preventing environmental contamination, especially in healthcare settings plays a vital role in controlling the disease. In this study, air and surface contamination with SARS-CoV-2 were evaluated in different wards of Hajar Hospital in Shahrekord. Materials and methods: In current study, 13 samples of different surfaces and 15 air samples were taken using sterile swabs impregnated with VTM and standard impinger, respectively. Detection of SARS-CoV-2 was performed using RT-PCR. Results: Findings showed that 46.15% of surface samples and 26.66% of air samples were positive for SARS-CoV-2 RNA. These contaminations were detected only in areas which were in close contact with COVID-19 patients. Conclusion: This study confirmed the contamination of air and surface with SARS-CoV-2 in COVID-19 admitting wards. Therefore, personal precautionary measures, including frequent hand-washing, timely changing of face mask, and using more protective equipment are highly recommended in healthcare settings. Moreover, cleaning and regular disinfection of surfaces and equipment and appropriate ventilation of wards are crucial for preventing the disease transmission.
