about 31 minutes.
Generally, the contaminated dishes and chopsticks in novel coronavirus should be boiled in water with a temperature of 56℃ or above for about 31 minutes, so as to effectively kill novel coronavirus and prevent others from infecting novel coronavirus after touching the contaminated dishes and chopsticks.
novel coronavirus is sensitive to ultraviolet rays and heat. Boiling in water at 56℃ or above for about 31 minutes, or using fat solvents such as ether, 75% ethanol, chlorine-containing disinfectant, peracetic acid and chloroform can effectively inactivate novel coronavirus. It should be noted that chlorhexidine cannot effectively inactivate novel coronavirus.
Therefore, the bowls and chopsticks used by infected people in novel coronavirus need to be boiled in water at a temperature of 56℃ or above for about 31 minutes to kill the novel coronavirus in the bowls and chopsticks and reduce the possibility of others being infected with novel coronavirus.
Precautions
When disinfecting tableware, you need to pay attention to your own safety to avoid scalding. Generally, after 31 minutes of high-temperature disinfection, novel coronavirus on tableware will be basically killed. If you feel uneasy, you can appropriately extend the disinfection time or increase the disinfection frequency to ensure the safety of using tableware. You can also use ultraviolet rays for disinfection: ultraviolet rays have the efficacy of sterilization and disinfection, and novel coronavirus is highly sensitive to ultraviolet rays. Placing the tableware of patients infected with novel coronavirus in an ultraviolet disinfection cabinet can also play a role in disinfection.
After being infected with novel coronavirus, it is necessary to keep indoor air circulation. When there are mild symptoms, such as cough, low fever, headache, etc., it is enough to isolate at home. During the treatment, it is necessary to drink more water and eat more fresh vegetables and fruits, such as lettuce, cucumber, apples, etc., which is helpful to enhance your immunity.
