People with positive infections of the new coronavirus
After home treatment and recovery, many people are still worried:
quilts and bed sheets at home
Will hiding virus be infected again?
How to disinfect the home where "yanghe" is "yanghe"?
When will you return to work and not cause new infections?
These questions, one article answers
Are there any virus residues on clothing and daily necessities? After the
positive infected person recovers, are there any virus residues on the 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:
01
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.
02
viruses need 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.
03
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℃.
04
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.
viruses need to be replicated in living cells, and clothing cannot provide this environment. The virus survives for a long time at low temperatures, shorter survival time at high temperatures, and very shorter survival time at 56℃ or above. It can be solved by washing clothes normally or soaking them in hot water.
How to disinfect at home?
Pay attention to these key parts!
Many "sunrise" have been recovered and hope to undergo a "terminal disinfection" from the inside out at home. 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 the cross-infection of a large number of viruses, 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 parts 1: Refrigerator - Alcohol wipes or chlorine-containing disinfectant wipes
The most likely place to remain in the family 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 positively infected person sneezes or coughs while opening the refrigerator and sprays sputum into the refrigerator, which may cause the refrigerator to 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
Home wash basin and toilets may retain respiratory tract secretions during the illness of infected people. After recovery from "positive" recovery, you can use alcohol wipes or chlorine-containing disinfectant to wipe 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, cotton items such as clothing, bedding, etc. - drying and heating viruses can lose their activity.
cotton items can be cleaned 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 based on cleaning and supplemented by disinfection.
Preferential use of 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.
Home disinfection guide
One picture to understand
Return to work guide
According to the "Diagnosis and Treatment Plan for 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.
How long does 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 Tongzhang, 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, take another 3 days of rest.
Usually, after 3 days after normal body temperature, 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" is recommended to wear masks and not lower the prevention and control standards after returning to work.
is currently in the high incidence of respiratory infections in winter. In addition to , 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.
