The length of time that a new coronavirus can survive in vitro is related to the specific adherent material. 1. Floating in the air: the new coronavirus can generally only survive for about 3 hours when floating in the air, and once adhering to the material, it can prolong its life. 2. Surface of copper material: generally can survive for about 4 hours. Copper for the new crown virus has a relatively strong inhibition ability, with copper ions have a disinfection effect has something to do with. 3. Cardboard: on the cardboard similar to the express box, the new crown virus can generally survive for about 24 hours. 4. Stainless steel and plastic surfaces: in the relatively smooth stainless steel and plastic surfaces, the new crown virus may survive for 2 to 3 days. Especially in the narrow space of the elevator, it is easy to cause the spread of the new crown virus type. New coronavirus is highly contagious, you need to wear a mask when you go out, get vaccinated, and actively do related preventive work.
