چکیده

زمینه وهدف:
COVID-19 می تواند مستقیماً از طریق قطرات تنفسی یا غیرمستقیم از طریق وسایل که باعث انتقال عفونت می شوند منتقل شود .این تحقیق با هدف شناسایی ویروس در محل های تماس بیماران مبتلا با سطوح مختلف آلوده به ویروس از قبیل آمبولانس حمل بیماران، محل های نمونه گیری ، اتاق های معاینه ، اتاق های بستری و آزمایشگاه به انجام رسید
مواد وروشها:
نمونه برداری ها بر اساس دستور العمل سازمان جهانی بهداشت انجام شد، نمونه های محیطی با استفاده از یک سواب و با نوک مصنوعی و یک شافت پلاستیکی انجام گرفت در این مطالعه سعی شد نمونه برداری در ساعت های شلوغ بیمارستان انجام گیرد و تعداد کل نمونه ها 48 نمونه برداشت گردید و در نهایت نمونه ها توسط روش واکنش زنجیره‌ای پلیمراز-رونویسی معکوس (RT-PCR)مورد سنجش قرار گرفت.
یافته ها:
نتایج نشان داد که داخل 36 نمونه بیمارستان 8 نمونه مثبت بوده و در 10 نمونه آزمایشگاه جامع نیز دو نمونه مثبت گزارش شده است با توجه به غیر نرمال بودن داده ها برای مقایسه مجموعه های داده های سطوح مختلف از قبیل (پلاستیکی،فلزی، چوبی،شیشه، الیاف و جسم زنده) از آزمون Kruskal-Wallis استفاده شد. طبق نتایج بدست آمده بین سطوح با جنس ها مختلف و میزان مثبت بودن تستها ارتباط معنی داری مشاهده نگردیدpvalue=0.341) ).
نتیجه گیری:
قطرات تنفسی آلوده می توانند توسط جریان هوا جابجا شده و روی سطوح رسوب کنند. با توجه به نوع سطوح و ماندگاری بالاتر این ویروس ها بر روی این سطوح لزوم ضدعفونی مرتب و روزانه قبل و بعد شیفت و در مواقع مواجهه با آلودگی با ویروس حتما باید با ترکیبات ضد ویروسی مناسب با سطح، گندزدایی گردند. در مورد بقیه سطوح مانند پارچه و الیاف آلودگی دیده نشده است ولی با توجه به سرایت این ویروس باید احتیاط های لازم در نظر گرفته شود.

چکیده [English]

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.
