How long the new coronavirus can survive on the express depends on two points, the first is whether the environment for transporting and storing the express is suitable for the survival of the new coronavirus, and the second point is the express material. New coronavirus in the normal environment can survive 1-3 days, from the epidemic epidemic, the new crown outbreak in winter and spring, indicating that in the cold, humid climate is more suitable for the survival of the new crown virus, while the hot and dry summer may affect the survival time and activity of the virus. Therefore, if the location of the transport courier or storage courier is colder and more humid, the survival time of the new coronavirus on the courier may be extended, possibly up to 2-4 days. In addition to the environmental impact, the material of the courier will also affect the survival time of the new coronavirus. Generally speaking, common couriers include materials such as paper shells and plastics. From the available studies, the survival time of New Coronavirus on plastic products is longer than that on paper products. Combined with the above two points, if your courier is plastic packaging, transport and storage environment and more wet and cold, survival time may reach 2-4 days, if your courier is paper packaging, transport and storage environment is dry, survival time may also be 1-2 days. To reduce the spread of the new coronavirus caused by the residue on the surface of the courier, the courier can be received in the sun, but also apply disinfectants such as 75% alcohol, chlorine disinfectant, 84 disinfectant, etc. to disinfect its surface, while contact with the courier, to promptly clean and disinfect the hands, etc. In addition, the new coronavirus can also be spread through droplet transmission and aerosol transmission, so attention should be paid to wearing masks properly in public places, washing hands regularly and ventilating more often on a daily basis to reduce the risk of virus transmission.
