The most likely place in the home where the coronavirus is left is the refrigerator. **The temperature in the refrigerator is 4-5℃, and the temperature in the freezer is -18℃, both of which are very suitable for the virus to survive. In an extreme scenario, if a positive infected person opens the refrigerator and sneezes or coughs, spraying sputum into the refrigerator, the refrigerator may be contaminated with the virus.

Li Dongzeng, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital and medical expert at Xiaotangshan Fangcang Hospital, suggested that infected people should try not to touch the refrigerator and cook for their families. If you cook for yourself, after you recover, it is best to turn off the power to the refrigerator and let it return to room temperature for about a day . "Generally, the new coronavirus has been eliminated in the environment within one day and is no longer contagious."

He said that the refrigerator may be the "most difficult place". In other places, when people stop excreting viruses, the viruses in the environment will lose their infectiousness after a day.

Some experts suggest that after recovering from a positive test, you can unplug the refrigerator and wipe it with alcohol wipes . Food that is not sealed in a refrigerator can be heated before eating to eliminate the virus.

Home disinfection, how to prevent the epidemic scientifically,

Avoid “over-prevention”?

If there are positive symptoms at home, many families will spray alcohol and disinfectant everywhere. Is this reasonable? Can alcohol spraying disinfection be used at home?

A: If a family member shows positive symptoms, it is best to move to a bedroom with a separate bathroom for isolation and symptomatic treatment. If conditions do not permit, they should also be isolated in the original bedroom. All family members should wear masks, wash hands frequently, and ventilate more as soon as possible. On the premise of keeping the patient's door closed, fully ventilate other bedrooms, living rooms, bathrooms, kitchens, etc., and wipe and disinfect environmental surfaces such as the ground and living room walls, as well as high-frequency contact surfaces such as countertops, sofa armrests, door handles, faucets, and flush buttons. It is best to use disinfectants such as 84 disinfectant or chlorine dioxide effervescent tablets on the surface of environmental items, and prepare and use them according to the instructions. Alcohol is not suitable for large-scale spraying and disinfection because it evaporates too quickly and has flammable risks. It is generally only used for hand and skin disinfection, as well as wiping and disinfection of remote controls and small electronic products. Tableware for positive people needs to be used separately and boiled for disinfection.

How should we disinfect our homes? Will the larger the spraying range and the more frequent the spraying, the better the disinfection effect? ​​What is the scientific spraying range and frequency?

Answer: Opening windows for ventilation, cleaning and disinfecting environmental surfaces are appropriate and effective ways to disinfect homes. Wet wiping is the main method for disinfecting the surfaces of the home environment. You can use disinfectant to mop the floor, or wipe with a rag dipped in disinfectant. If you prefer spraying disinfection, it is recommended to hold a small spray bottle in one hand and a rag in the other, spraying and wiping evenly. If there are no positive people in the home for the time being, wiping and disinfecting once a day is sufficient; if there are positive people, the frequency of disinfection can be appropriately increased, with a focus on the bathroom shared by patients, which needs to be disinfected once a patient uses it. The tableware of positive people needs to be boiled and disinfected once used.

Are there any virus residues on clothes and daily necessities during the infection period? Will it cause secondary infection? Is it necessary to disinfect these clothes and daily necessities?

A: There may be virus residues on clothes and daily necessities during the infection period, but the virus will not survive outside the body for too long and will not cause secondary infection if properly handled. It is recommended to pack and seal clothes and daily necessities during the infection period for about a week, and then wash or clean them as usual. For moisture-resistant and heat-resistant clothes, bedding, etc., they can also be washed at high temperature or soaked in special clothing disinfectants for disinfection.

Which areas or furniture in the home are the focus of disinfection?

A: The front door and bathroom are the key areas for home disinfection. Key areas are those that are frequently touched by hands, such as door handles, countertops, faucets, flush buttons, switches, remote controls, mobile phones, tablets, etc.

For families with positive patients at home, what are the must-do home disinfection? What is unnecessary? What should not be repeated?

Answer: Opening windows for ventilation and disinfecting shared areas are mandatory. Families with positive patients should open windows for ventilation at least twice a day for about 30 minutes each time. It is best to ventilate the patient's room at different times from other rooms. Shared areas such as shared toilets, storage counters at the door of the patient's bedroom, and domestic garbage should be disinfected. Environmental surfaces should be wiped and disinfected and mopped with disinfectant. Domestic garbage should be packed in double-layer garbage bags and the bags should be tied tightly, and the surface should be sprayed with disinfectant.

For families that do not have any positive patients, how should they carry out home disinfection under the current epidemic prevention and control situation?

Answer: Families with no positive test results should pay attention to opening windows for ventilation and cleaning and disinfecting the home environment. Family members should wash their hands or disinfect their hands immediately when they return home. The entrance area and bathroom can be wiped and disinfected every day.

In addition, it is important to remind you that the current epidemic situation is not yet time to relax. You need to continue to take personal protection measures, wear masks in public places, wash your hands frequently, keep your distance, ventilate your home environment frequently, and do a good job of cleaning and disinfection. If you are really infected, don't panic, rest at home and treat the symptoms, and wait for the virus to turn negative.

Preparation method of household disinfectant

1. Simple dilution method of 84 disinfectant:

The effective chlorine content of commercially available 84 disinfectant is generally around 5%. After dilution at 1:100, it can be used to disinfect the surface of objects in the home environment (500mg/L). Simple configuration tools: 84 disinfectant cap (generally 10ml), common mineral water empty bottle (select 500ml). The preparation method and steps are: wear a mask and plastic gloves, take a clean plastic basin and rag, add 1 cap of 84 stock solution to the basin, add 2 bottles of tap water, and mix well to make a 1:100 dilution.

2. Preparation method of chlorine dioxide disinfectant:

The effective content of commercially available chlorine dioxide effervescent tablets is generally about 10%, and the weight is 1g/tablet. For home disinfection, 200mg/L~300 mg/L concentration can be used. The preparation method is: open the bathroom window, prepare the disinfectant in the bathroom, wear a mask and plastic gloves, take a clean plastic basin and rag, add 2~3 effervescent tablets to the basin, and then add 2 bottles of tap water (500ml/bottle), dissolve and mix to obtain 200mg/L~300mg/L concentration of chlorine dioxide disinfectant.

Once they have fully recovered and are back to their daily home lives, "Yang Guo" and "Yang Kang" will no longer need to disinfect every day.
