چکیده

ظهور کرونا-‌ویروس جدید انسانی SARS-CoV-2، که باعث عفونت‌های شدید دستگاه تنفسی در انسان می‌شود، به یک نگرانی بهداشت جهانی تبدیل شده است. هدف ما، مرور اطلاعات در خصوص پایداری و ماندگاری کرونا- ویروس‌ها بر روی سطوح غیر زنده و میزان کارایی عوامل کشنده زیستی بود تا اطلاعات واضحی برای جلوگیری از گسترش انتشار بیماری COVID-19 ارائه نماییم. این مطالعه، یک بررسی نظام‌مند است که با مراجعه به سایت‌های بین المللی و داخلی با استفاده از کلید واژه‌های تخصصی در موتورهای جستجوی اصلی انجام و نتایج جستجو گردآوری شد. سپس منابع اصلی مرتبط با هدف این مقاله، شناسایی، استخراج و دسته‌بندی گردید و در نهایت مورد تجزیه و تحلیل قرار گرفت. ویروس SARS-CoV-2 توسط قطرات تنفسی، ذرات معلق در هوا و از طریق مدفوعی به سطوح و محیط منتقل شده و پس از لمس سطوح آلوده به‌صورت خود تلقیحی به بینی، دهان یا چشم‌ها منتقل می‌شود. این ویروس می‌تواند تا 9 روز بر روی سطوح فولاد ضد زنگ، شیشه و پلاستیک به‌صورت عفونت‌زا باقی بماند. برخی از عوامل رفع آلودگی کننده نظیر اتانول 71-62 درصد، پراکسید هیدروژن 5/0 درصد و هیپوکلریت سدیم 1/0 درصد می‌توانند به‌طور موثری در مدت 1 دقیقه میزان عفونت کورنا-ویروس را کاهش دهند. ولی سایر ترکیبات از جمله بنزالکونیوم کلرید 2/0 الی 05/0 درصد یا کلرهگزیدین دیگلوکونات 02/0 درصد اثر کمتری دارند. بیماری جدید COVID-19  نکات مبهم زیادی دارد و هنوز واکسن، دارو و درمان مناسبی برای آن وجود ندارد و برنامه‌های استاندارد مراقبت، پیشگیری و کنترل، نقش مهمی در مبازره با این ویروس دارد. گندزدایی و ضد‌عفونی کردن سطوح و محیط، بهترین اقدامات برای پیشگیری و جلوگیری از انتشار بیماری COVID-19 است.

چکیده [English]

The emergence of a novel human coronavirus, SARS-CoV-2, which causes severe respiratory infections in humans, has become a global health concern. Our objective is to review information about sustainability and persistence of coronavirus on non-living surfaces and the efficiency of lethal factors to provide clear information for preventing the spread of COVID-19 disease. Research Method: This study is a systematic review conducted by online browsing of national and international websites using the specialized keyword in the main search engines and collecting the results. Then the main sources related to the purpose of this article are identified, extracted and classified and finally analyzed. The SARS-CoV-2 virus is transmitted to the surfaces and the environment through respiratory droplets, suspended particulates in the air and the feces. After touching the contaminated surfaces, it is transmitted by self-inoculation in the nose, mouth, or eyes. It can remain infectious on stainless steel, glass and plastic surfaces for up 9 days. Some disinfectant agents like 62-71% ethanol, 0.5% hydrogen peroxide and 0.1% sodium hypochlorite significantly reduce the coronavirus infectivity within 1 min exposure time. In contrast, 0.2-0.05% benzalkonium or 0.02% chlorhexidine digluconate were less effective. The new COVID-19 disease has many vague points, and there is still no medicine and proper treatment for it. Standard surveillance, prevent and control plans have an important role in fighting the virus. The best way to prevent the spread of COVID-19 is disinfection of surfaces and the environment.
