A. What should I do when I go home? If you are at home in an open environment, you can change your clothes, take off your mask and wash your hands normally when you get home. The pathogens of respiratory-related diseases are mainly spread by droplets, with a transmission range of about 1 meter. Wear a mask when you go out, cover your nose and mouth with a tissue when you sneeze or cough, wash your hands and change your clothes in time to meet the protection requirements, and there is no need to panic too much. If you return home from a crowded place, such as a train station or hospital, it is recommended that you disinfect your clothes. If the clothes are not contaminated by pollutants, spray the whole body with 75% alcohol, and then dry them on the balcony for ventilation. If it has been contaminated by pollutants, you can use 500mg/L chlorine disinfectant solution soaked for 30min, and then wash and dry with water. Second, the home environment disinfection? How to disinfect? Unless there is a suspected infected person at home, no special disinfection is needed. If you have not been in contact with confirmed or suspected cases, and have hardly been out and about recently, there is no need to be overly nervous about the new coronavirus, and your home environment is relatively safe. However, if you are concerned, disinfect areas of your home that are frequently touched, such as cell phones, doorknobs, floors, etc. One thing to keep in mind is that if the surface of the object to be disinfected is dirty, it needs to be cleaned first and then disinfected. You can use alcohol wipes with a concentration of 75%, or you can use diluted sodium hypochlorite, which is often referred to as 84 disinfectant. The general dilution ratio of 84 disinfectant and water is 1:100. Don’t forget to wear rubber gloves and a mask when configuring, and operate according to the product package instructions. Third, get takeaway or express, need to disinfect? Just wipe the outer packaging with alcohol. If you are worried about the indirect contact brought by the delivery, you can let the delivery boy put it at the door, and then take it into the house when he leaves (both sides are not in direct contact, relatively safe), then wipe the outer packaging with alcohol and wash your hands before opening it for consumption, which will also reduce the risk. As for the courier, different viruses have different survival times outside the human body, and the virus contaminated during the delivery process may have died long ago. But the recent delivery and distribution of the virus is still alive, you can also directly wipe the packaging with alcohol after receiving it to reduce the risk. Fourth, how to properly open the window ventilation? At present, there is no explicit provision for ventilation at home and abroad. Therefore, it is recommended that ventilation should be based on the indoor and outdoor environment. When the outdoor air quality is good, ventilation can be done in the morning, midday and evening, for 15-30 minutes each time; when the outdoor air quality is poor, the frequency and time of ventilation should be reduced appropriately. If there are elderly people and babies at home, pay attention to ventilation of the living room under the premise of keeping warm. V. How to disinfect dishes after meals? First of all, wash thoroughly to remove food residues adhering to the dishes. If you have a dish sterilizer at home, you can choose the high temperature sterilization mode directly, note that the temperature must be greater than 56℃ and the time lasts 30 minutes. If you do not have a sterilizer at home, you can boil the dishes directly after cleaning and disinfection, and the boiling time should last at least 15 minutes. Six, family members common cold, others need to wear a mask? Image source: Zhihu @ a little Tsubaki If someone in the family has a common cold, no one else needs to wear a mask. There is usually about 1L of fluid in the pleural cavity of a normal person, and when sneezing, it is like squeezing a mineral water bottle, turning this fluid into small drops that are dispersed outside the body, and each small drop contains a large number of bacteria and viruses. It is recommended that patients simply wear a mask, which serves to stop the spread of bacteria and viruses to others through droplet transmission. However, for health safety, it is still recommended to reduce contact with the patient and to disinfect the items used diligently. 7. What should I do if my neighbor or family member has a fever? Reduce communication, wear a mask if you must communicate, and keep a distance of more than 1 meter to avoid droplet transmission. Do not worry that it is impolite to wear a mask when you see your elders or friends. During special times, this behavior is the most knowledgeable and safer for everyone! If contact occurs accidentally, or indirectly, wipe with alcohol and wash your hands. If you have a fever or cough, nasal congestion, sneezing or other symptoms, please also consciously reduce contact with others and promptly go to the local prescribed designated hospital for testing. Wear a surgical mask when you go out, cover your mouth and nose with a tissue when coughing and sneezing, and wash your hands regularly when you return home. Eight, should I stock up on medication at home? First of all, for the new coronavirus infection, neither the existing flu vaccine nor the pneumonia vaccine has any preventive effect on this viral infection. Currently, professionals are intensifying their research on the viruses involved in this infection, but it will take some time. Second, some cold and flu medications taken indiscriminately can instead mask the symptoms of the new pneumonia and delay clinical judgment. Finally, others, such as antibiotics and hormones, are not easy for the general public to master the selection and usage of drug varieties, even if they are used by doctors in the treatment process, so it is not recommended to stock up on your own. What should I do if my family members have suspicious symptoms? 1.If there are suspicious symptoms of pneumonia caused by novel coronavirus infection (such as fever, cough, sore throat, chest tightness, dyspnea, fatigue, slightly poor mental health, nausea and vomiting, diarrhea, headache, panic, conjunctivitis, mild muscle pain in the limbs or lower back, etc.), you should seek medical attention according to your condition. 2.Avoid taking public transportation such as subway and bus, and avoid going to crowded places. 3.When visiting the doctor, you should take the initiative to tell the doctor your travel and residence history in the relevant disease endemic areas and what people you have contacted after the onset of the disease, and cooperate with the doctor in the relevant investigation. 4.Family members of the patient should wear masks, keep a distance from other family members who are asymptomatic, and avoid close contact. 5.If someone in the family is diagnosed with pneumonia due to novel coronavirus infection, other family members who are judged to be close contacts should be placed under medical observation for 14 days. 6. Disinfect areas and objects that are frequently touched by symptomatic family members. 10. What should I do if I go out to walk my dog? There is no evidence that this coronavirus can be transmitted to cats and dogs. However, it is still recommended that pets, like their owners, should go out less often. If you walk your dog, in addition to wearing a muzzle yourself, remember to bathe your pet when you get home, using commonly used bath products. The purpose of bathing is to clean, just like we wash our hands with soap, mainly to avoid pets carrying viruses that have infected people.
