Latest research: Plastic and stainless steel surfaces are most conducive to the survival of new coronavirus

An important paper has been submitted to NEJM to directly detect the survival time of the new coronavirus outside the human body for the first time: plastic and stainless steel surfaces are most conducive to the survival of the new coronavirus, which can survive up to 3 days. Followed by cardboard, the survival time is up to 24 hours. The shortest survival time is the copper surface, only 4 hours. In aerosols, the new coronavirus can survive for up to 3 hours.

The above results were made under the conditions of relative humidity 40% ~ 65% and temperature 21 ℃ -23 ℃. The survival time of the new crown virus on the surface of objects of different materials can be more than ten times different. The previous judgments mostly refer to the data of other viruses, but this time the direct detection also shows that the survival time of the new coronavirus and SARS virus is basically the same.

In short, under the current weather conditions, the new coronavirus can survive up to 2 to 3 days away from the human body. Combined with the previous sample test results of various wards, the most important places to pay attention to in daily life include public handrails, door handles, switches, tables and chairs, toilets, etc., and wash hands in time after contact. Try not to gather in a confined space, often ventilated indoors.
