How long does the novel pneumonia virus survive in these?

The novel coronavirus is sensitive to ultraviolet light and heat, and can be inactivated at a temperature of 56°C in 30 minutes. Lipid solvents such as 75% ethanol, chlorine-containing disinfectants, peracetic acid, and chloroform are all effective in inactivating the novel coronavirus.

1. Survival time in the natural environment

1. Air: The new coronavirus is mainly transmitted through respiratory droplets, but can also be transmitted by aerosols (through the droplets containing the virus suspended in the air to form an air nucleus, and then suspended in the air for a long time).The survival time of the novel coronavirus in the air is related to external environmental factors, such as humidity, wind speed, and the length of exposure to sunlight.

2. Surface of items: The novel coronavirus can exist on the surface of objects and can remain active for a period of time, but it is not clear how long it can survive, under normal circumstances, the new coronavirus can survive for about 48 hours on smooth objects and about 24 hours on cardboard objects.

2. Artificial environment

1. Low temperature environment: If the new coronavirus is placed in an environment below -70 °C, it can generally be stored for a long time and will not deteriorate for several years;

2. High temperature environment: If the new coronavirus is placed in boiling water for heat treatment, it may cause the new coronavirus to become inactive, so that it can no longer be transmitted to others.

People are advised to wear masks when going out and avoid going to crowded places to avoid infection. At the same time, pay attention to personal hygiene, wash hands frequently, and exercise appropriately to enhance physical fitness. If symptoms such as fever occur, you should go to the respiratory medicine department of the hospital in time to complete the blood routine examination, lung CT examination and other clear diagnosis.
