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