There are several places in the home that should be disinfected the most
Some suspected patients with mild symptoms or asymptomatic people with a clear history of exposure can self-isolate and observe to ensure the safety of themselves, their families and friends.
What do you do when you're self-isolating?
Ke Huixing, chief physician of the Department of Respiratory and Critical Care Medicine of Beijing Hospital, suggested:
Patients are best left alone, and living with others requires a well-ventilated room with less frontal contact with other members.
Try to wear a mask, disposable gloves, and protective clothing (such as a plastic apron); before wearing gloves, clean your hands after removing gloves and masks.
Make sure the shared areas (kitchen, bathroom, etc.) are well ventilated (keep the windows open).
Limit activities to minimize areas where quarantiners and family members can share activities.
On the basis of self-isolation, Wu Anhua, chief physician of the Infection Control Center of Xiangya Hospital of Central South University, recommends disinfecting the following places every day.
Air disinfection
Ventilate frequently
Open the doors and windows for ventilation 2 to 3 times a day, each time not less than 30 minutes, which is the best way. Families with conditions can use the circulating air disinfection machine, pay attention to strictly follow the instructions.
Disinfection of common goods
Alcohol wipe
Patients are easy to touch frequently every day, but also pay attention to daily disinfection, such as light switches, door handles, faucet handles, etc., can be wiped with 84 disinfectant or alcohol; tableware can be cleaned with detergent, or disinfected with high temperature.
Hand and skin disinfection
Wash with soapy water
Wash your hands with hand sanitizer or soap under running water, and if necessary, you can use disinfectants such as alcohol, chlorheptyl alcohol solution, and iodine.
toilet
Flush toilets should be covered with toilet lids
The novel coronavirus has the potential to spread through "fecal-oral", and sewers and toilets are at risk of spreading the new coronavirus.
Toilets and toilets should be disinfected, and toilets should be covered with toilet covers; for communities where sewers are not tightly closed, if reverse seepage or leakage is found, the sealing of toilets or toilets should be strengthened.
Personal belongings
Wash separately
Personal clothing, bed sheets, towels and other daily necessities are stored separately and washed separately from others. Refer to the recommendations of the World Health Organization, put it in a laundry bag, wash it with clean water, or use a washing machine to add ordinary household laundry detergent to the water temperature of 60 to 90 degrees Celsius, and then completely dry the above items.
The use of disinfectants is contraindicated
Since the outbreak of the epidemic, alcohol and 84 disinfectant have become common disinfection supplies in people's homes, but improper use may bring new problems.
alcohol
Pay attention to fire prevention
Alcohol is flammable, Beijing Tongzhou District Fire Brigade fire propagandist Qi Xinglong reminded that with alcohol disinfection should pay attention to fire prevention.
Do not spray large areas of the body or the surface of the object, after the body sprays alcohol locally, make sure that the alcohol is away from the source of fire before it volatilizes.
Do not spray alcohol when taking buses, planes, high-speed rail and other means of transport to avoid increasing the risk of accidents.
Do not spray alcohol in the kitchen, especially near the stove, near the gas station, and near the oven and other high-power appliances.
In the summer, the temperature of the car dashboard can reach more than 80 ° C after being exposed to the sun, and it is easy to explode and burn when alcohol is released. It is best to wipe and disinfect before getting on the bus, and then get on the bus after confirming that the alcohol has evaporated.
84 disinfectant
Avoid other cleaning agents
84 disinfectant is a chlorine-containing disinfectant, mainly suitable for scrubbing the surface of objects. Li Chunhui, deputy chief physician of the Infection Control Center of Xiangya Hospital of Central South University, reminded that the use of 84 disinfectant should avoid the following misunderstandings:
The addition of "84" in laundry detergent will have a chemical reaction, weakening their respective effects, and will also lead to the production of chlorine gas, which stimulates people's eyes, nose, throat and other organs.
84 Disinfectant and toilet cleaner mixed will also produce chlorine gas. After cleaning with toilet cleaners, be sure to use 84 disinfectant at intervals of more than half an hour.
Do not dilute with the effect. 84 disinfectant is usually diluted with water and then used, the concentration of 300 ~ 500 mg / liter of 84 disinfectant water, dilution method is to find a capacity of 550 ml mineral water bottle, two caps of 84 disinfectant and 3 bottles of water mixed, stir evenly. ▲
