At present, the resumption of work and production in various places is on the verge of onset. During this period, many positive COVID-19 infections have gradually recovered after home treatment. But the "sunny" people are really worried: Will the quilts and sheets at home hide virus and become infected again? How should the "yang Kang" be disinfected at home that is "yang Kang"? When will you return to work and not cause new infections? Beijing News Broadcast reporter interviewed Lu Lian, director of the Hospital Infection Management Department of Beijing Ditan Hospital, and Li Dongzeng, chief physician of the Comprehensive Infection Department of Beijing You'an Hospital and medical expert of Xiaotangshan Fangcai Hospital. Please accept this "Yangkang" guide!
Residual "favorites" of the new coronavirus
Many "sunshine" have experienced about 7 days of "fighting the epidemic at home" and are now gradually recovering. Are there any virus residues on clothing and daily necessities during the infection? Will it cause to secondary infection with ? Lu Lian, director of the Hospital Infection Management Office of Beijing Ditan Hospital, said that the risk of being infected by items at home after "Yang Guo" is very small. This is related to the characteristics of the virus:
1. The new coronavirus is transmitted through the respiratory tract and the possibility of spreading from the surface of the object is very small, and it is not the main transmission route. The new coronavirus has a limited survival time on smooth objects, such as metal surfaces and hard desktop surfaces.
2. The virus needs to survive in the human body. Studies have shown that when the virus leaves the human body, it will lose its activity within 2 to 3 hours at room temperature, dry and hard surfaces, and it will no longer be contagious.
3. The new coronavirus is not afraid of cold or heat. In a conventional laboratory, it loses activity at a temperature of 56°C for 30 minutes. The bath water will definitely be inactivated for about 50℃ for 30 minutes. The higher the temperature, the more effective it is. In theory, it can kill the virus in just 1 minute at a high temperature of 90℃.
4. Sputum is the "hotbed" of viruses. Because sputum can maintain a certain temperature and humidity, viruses are included, especially when the temperature is low in winter. If it is still in a water environment, it is possible to survive for more than ten days.
"Yang Kang"Home Disinfection Guide
After recovering, I hope to undergo a "terminal disinfection" at home from the inside out. Lu Lian, director of the Hospital Infection Management Office of Beijing Ditan Hospital, said that the so-called "terminal disinfection" in the hospital is due to a large number of virus cross-infection, and it is necessary to avoid infection of immunodeficiency patients who come to the hospital. Disinfection is only required in special areas, such as toilets and refrigerators. Just do daily cleaning of the home without terminal disinfection. "Yangyu" can be classified and cleaned according to the following materials:
1. Key part 1: Refrigerator - Alcohol wipes or chlorine-containing disinfectant wipes
The most likely place in the family to remain in the new coronavirus is the refrigerator. The refrigerator compartment is 4-5℃ and the freezer compartment is 18℃, which are both very suitable for virus survival. Extremely hypothesis: a person with positive infection sneezes or coughs while opening the refrigerator, and sprays sputum into the refrigerator, which may be infected with the virus. Experts suggest that after recovering from "sunday", you can unplug the refrigerator and wipe the refrigerator with a wet wipe containing alcohol. Foods without airtight packaging in the refrigerator can be heated and then eaten to eliminate the virus.
2. Key parts 2: Toilet - wipe alcohol wipes or chlorine-containing disinfectant
The bathroom sink and toilet in the home may retain respiratory secretions of infected people during the illness. After recovery from "positive" rehabilitation, you can wipe them with alcohol wipes or chlorine-containing disinfectant for disinfection.
3. Desktop, cabinet and other hard surfaces - wipe alcohol wipes or chlorine-containing disinfectant
The survival time of the virus on the hard surface is limited, just wipe with alcohol or chlorine-containing disinfectant. At the same time, pay attention to opening the windows for ventilation. Special reminder: Never use spray containing alcohol. Alcohol can easily explode when you see fire in the air.
4. Clothing, bedding, bedding and other cotton items - drying and heating viruses can lose their activity.
Cotton items can be washed normally in the washing machine, and can also remove pathogens while washing and removing dirt. Take the quilt to the sun and bask in it. If a washing machine has heating and disinfection function, the virus will be inactivated in theory at a temperature of 56℃ for 30 minutes.
5. Home disinfection should be mainly clean and disinfection should be supplemented.
Preferring priority to using physical disinfection methods such as sun exposure and heat at home. It is recommended to ventilate 2-3 times a day, each time at least 30 minutes. Home disinfection should be mainly cleanliness and chemical disinfection should be supplemented.
"Yang Kang" return to work guide
As the "Yang Zhu" gradually recovered, many places have also pressed the "fast forward key" to resume work and production. According to the "Diagnosis and Treatment Plan for the New Coronavirus Pneumonia" (Ninth Edition), the standards for patients to recover and discharge are: First, body temperature returns to normal for more than 3 days; Second, respiratory symptoms improve significantly; Third, lung imaging shows that acute exudative lesions have improved significantly; Fourth, two consecutive nucleic acid tests were negative, and the Ct value is ≥35.
Nowadays, many asymptomatic infected patients with and mild patients choose to recover at home. How long will it take to return to work after the fever is reduced and it will not cause virus infection? What should “Yangkang” pay attention to when it comes to contact with people? Li Tong, chief physician of the Comprehensive Infection Department of Beijing You'an Hospital and a medical expert at Xiaotangshan Fangcang Hospital, said:
Return to work Reference 1: After 7 days of onset of the disease, nucleic acid gradually turned negative and was less contagious.
3 days after the onset of the disease, the body temperature of young and middle-aged people gradually returned to normal, but the cough and sore throat were still serious. From a clinical point of view, most patients with mild symptoms began to turn negative nucleic acid 7 days after onset, and the amount of virus is also very low, which is basically not contagious.
Return to work Reference 2: After the body temperature returns to normal, rest for another 3 days.
Usually, after 3 days after the body temperature is normal, the symptoms of cough, nasal congestion, runny nose and sore throat may be significantly relieved. When your sore throat and cough no longer affects your sleep, it means that your body has basically recovered and is suitable for returning to work!
Return to work reminder: "Yangkang" returns to work and recommends wearing masks and not lowering prevention and control standards.
is currently in the high incidence of respiratory infections in winter. In addition to , the new crown , there are other infectious diseases. It is strongly recommended that respiratory protection should be taken after the recovery from the new crown and do not lower the prevention and control standards. After returning to work, he insists on wearing a mask in public places with many people, pay attention to hand hygiene, coughing, sneezing and other etiquettes. Don't eat face to face in the cafeteria.
Return to work expects: "Yangkang" may be extremely low in the "Double Ninth Festival" within half a year, and the body will maintain a high antibody level.
Generally, young people are unlikely to be infected with the new coronavirus twice within half a year. Especially in the 3 to 6 months after infection, the antibodies in the body remain at a very high level, and have cross-protective effects on the small virus mutation . Li Tongzeng suggested that one more dose of vaccine will strengthen immunization after half a year, and will obtain a higher level of protection.
