Background and Purpose: COVID-19 can be transmitted directly throughrespiratory droplets or indirectly through devices that transmit infection.SARS-CoV 2 has been identified on various environmental levels in hospitalsand communities.Material and Methods: Sampling was done according to the instructions ofthe World Health Organization; environmental samples were taken using aswab with an artificial tip and a plastic shaft. In this study, sampling was doneduring the busy hours of the hospital and the total numbers of samples 48samples were collected and finally the samples were analyzed by polymerasechain reaction-reverse transcription (RT-PCR) method.Results: The results showed that within 36 samples of the hospital, 8 sampleswere positive and in 10 samples of the comprehensive laboratory, two positivesamples were reported. Due to the abnormality of the data, the Kruskal-Wallistest was used to compare datasets of different levels such as (plastic, metal,wood, glass, fibers and living body). According to the results, no significantrelationship was observed between levels with different genders and thedegree of positive tests (P value = 0.341)Conclusion: Contaminated airborne droplets can be displaced by air currentsand deposited on surfaces. Due to the type of surfaces and higher durabilityof these viruses on these surfaces, the need for regular and daily disinfectionbefore and after shifts, and in case of exposure to virus infection, must bedisinfected with appropriate antiviral compounds with the surface. Nocontamination has been observed on other surfaces such as fabrics and fibers,but due to the spread of this virus, necessary precautions should be taken.
