How long does the novel pneumonia virus survive after leaving the body

After the new pneumonia virus leaves the human body, if it survives in the air for a short time, it will become inactive within 5 minutes. If it is attached to the surface of an object, it can usually remain active for 6 hours.

1. Air

The novel coronavirus is sensitive to ultraviolet rays and heat, is not resistant to high temperatures, and can be inactivated in 30 minutes at temperatures above 56°C. Heating at 100°C for 2-3 minutes can be completely inactivated. After the novel coronavirus leaves the human body, it quickly loses its activity in the air.

Second, the surface of the object

1. Hands: The novel coronavirus survives on the hands for a relatively long time, about 48 hours. Since the hands are one of the parts that have the most contact with the outside world, the novel coronavirus on the hands can easily be transmitted to others through contact;

2. Doorknobs: The new coronavirus can survive on doorknobs for about 7 days, so try not to touch public facilities such as elevator buttons during the epidemic. If it must be touched, it can be disinfected with alcohol or wiped with a chlorine-based disinfectant.

3. Tabletop: The novel coronavirus can survive on the tabletop for a few hours to a few days, so it is recommended to disinfect it frequently with alcohol, and you can also use a chlorine-based disinfectant to wipe down the table.

In addition to the above, the novel coronavirus can also exist on items such as mobile phones, computers, faucets, sinks, etc. In daily life, it is necessary to pay attention to protective measures to avoid infection with the new coronavirus.
