In order to deepen the public's understanding of New Coronavirus, we should better promote preventive measures to let everyone know what health means to people. We need to let our children know what is happening around us! It is necessary to produce handwritten copies of knowledge about New Coronavirus pneumonia.
1、 What is coronavirus
Coronavirus is a kind of virus widely existing in nature. It is named because its morphology is similar to the crown under electron microscope. The discovery of New Coronavirus (WHO named 2019-nCoV, or 2019 New Coronavirus) is very different from SARS coronavirus and MERS coronavirus. Although New Coronavirus is a close relative of SARS, it has not shown the terrible character of SARS. Therefore, there is no need to panic.
Two, how to effectively prevent New Coronavirus
（1） Pay attention to cold protection and warmth, maintain indoor air circulation, and open windows for ventilation every day.
1. It can be ventilated in the morning, noon and evening, and each time is about 20 minutes. When the outdoor air quality is poor, the ventilation frequency and time shall be appropriately reduced;
2. When using the air conditioner, do not let the room temperature be lower than 16 ℃, otherwise it is easy to catch a cold. Keep the indoor humidity between 40% - 60%. Professional cleaning companies are regularly invited to clean and disinfect the filter screen, pipeline, fire damper and condenser.
（2） Frequent hand washing is an important way to protect yourself and others from diseases recommended by the World Health Organization.
1. Remember the seven step washing technique, and the time for hand washing and rubbing shall not be less than 15 seconds;
2. When there is visible dirt on the hands, washing hands with soap and running water can effectively reduce the contact and transmission of viruses;
3. If the dirt on your hands is not visible, you can wash your hands with soap and water or use alcohol containing hand sanitizer;
4. Wash hands immediately after coughing or sneezing, when caring for patients, before, during and after food preparation, before meals, after defecation, when hands are dirty, and after contacting or handling animals or animal excreta.
（3） Keep away from diseases and take protective measures
1. Go to less crowded places to reduce the possibility of exposure to viruses;
2. Wear effective protective masks when going out when necessary: when going to general open public places and not contacting patients, you can choose to wear medical surgical masks without excessive protection. If you contact a patient with suspected respiratory tract infection, you need to wear N95 mask. Wash hands before wearing the mask, or avoid touching the inner side of the mask during wearing the mask, so as to reduce the possibility of mask contamination. When wearing a disposable medical mask, distinguish the inside and outside, up and down of the mask. The light color side is the inside. It should be close to the mouth and nose, and the dark side faces outward; One end of the metal strip (nose clip) is above the mask. Fully unfold the folded surface, completely wrap the mouth, nose and jaw, and then press the nose clip to make the mask fully fit the face. The disposable mask needs to be replaced within 4 hours at most, or it also needs to be replaced when it is soaked by water vapor and loses its protective effect;
3. Avoid close contact with any person with cold or flu like symptoms without protection (including spitting in public places, touching eyes, nose or mouth), and avoid people spitting and sneezing everywhere;;
4. Avoid unprotected contact with farm livestock or wildlife. Pay attention to food safety. Cook the meat and eggs thoroughly. Separate the cutting board and knife for raw and cooked food. Wash hands between handling raw and cooked food;
5. When purchasing in the fresh market, wash hands with soap and water after contacting animals and animal products, and avoid touching eyes, nose and mouth. Avoid contact with sick animals and spoiled meat. Avoid contact with stray animals, garbage and wastewater in the market;
6. Sneeze in the right way: Note: it is wrong to cover your mouth with both hands to avoid the sneezing of droplet bacteria, because the droplets will remain on your hands. If you don't wash your hands and disinfect immediately, the bacteria will transfer to other items with your hands. After sneezing, touch the door handle, bus bracelet and office tables and chairs, In this way, viruses and bacteria are left and spread. The correct way to sneeze is to cover your mouth and nose with a paper towel, or bend your elbow to cover your mouth and nose.
3、 If you feel unwell, get medical attention in time
1. The symptoms of patients with this infection include: general symptoms: fever, fatigue, dry cough, gradual dyspnea, and some patients have mild onset symptoms without fever; Severe cases: acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis, bleeding and coagulation dysfunction. Most patients are moderate and mild, which can be prevented, controlled and treated.
2. In case of the above clinical manifestations, the nearest hospital fever clinic should be selected for medical treatment, wear a mask, and inform the doctor whether there is a similar patient or animal contact history, travel history, etc.
4、 Other precautions
If there are no special circumstances during the holiday, try not to go to the area where the epidemic has been found. If you have to go, take preventive measures and truthfully inform the counselor before the school starts. Before returning to school, if you have symptoms of respiratory tract infection such as fever and cough at home, please report to the counselor for leave, rest and treatment at home. You can return to school only after you recover.
