Science Brief: SARS-CoV-2 and surface (fomite) transmission for indoor community environments. ; CDC Director Dr. Rochelle Walensky said "disinfection is only recommended in indoor . Investigators in the NEJM article also assessed viral stability on copper surfaces. Keep in mind: Although SARS-CoV-2 can be detected on these surfaces for a particular length of time, the viability of the virus, due to environmental and other conditions, is not known. The COVID-19 virus can spread via direct contact, airborne transmission, or through droplets. For the study, scientists purposely put the COVID virus on food packaging for drinks, pastries, fruit, canned goods, drink cartons and other items. Examples include: While the NEJM article found that no viable virus could be detected on stainless steel after 3 days, researchers for the Lancet article detected viable virus on stainless steel surfaces for up to 7 days. (2020). We may be able to find some viable virus after a few days, but its thousands of times less than what was originally deposited by the cough. This is called airborne transmission. Coronavirus also doesnt particularly like to be out in the elements. Here's what we know On plastic, the original Wuhan strain survived for about 56 hours. Scrubbing hands together for 20 or more seconds is enough to, The novel coronavirus can spread through the air as well as contact with contaminated surfaces, such as plastic and stainless steel, where the virus.
