To be careful
Fight against the new crown epidemic and safeguard health and safety
Novel coronavirus, the characteristics of the new coronavirus, the process of epidemic spreading, and the clinical manifestation of the patient are introduced, and suggestions are made for individuals to do well in their own protection.

Academician of Chinese Academy of engineering, President of Nanjing Medical University, Professor of epidemiology, School of public health, Nanjing Medical University.
After listening to academician Shen Hongbing's explanation
Do you know how to take precautions?
Education microenterprises also sorted out several problems
Help you consolidate the knowledge of today's war "epidemic"
To be careful
Classroom knowledge
01
Where does this aggressive novel coronavirus come from?
A: the novel coronavirus gene sequence was analyzed and found that its homology with bat SARS like coronavirus was as high as 85%. It is speculated that, like SARS coronavirus, it may also come from natural host bat. However, the novel coronavirus's natural host and intermediate host are not yet conclusive.
02
What symptoms will novel coronavirus infection occur?
Answer: after the novel coronavirus is infected, the patients usually suffer from latent period of 3~7 days and no more than 14 days. The main symptoms are fever, fatigue, dry cough, and a few patients have nasal congestion, runny nose, diarrhea and other symptoms.
Most of the severe cases developed dyspnea one week later. The severe cases developed rapidly into acute respiratory distress syndrome, septic shock, metabolic acidosis and coagulation dysfunction.
From the current situation of the cases, most patients have a good prognosis, a few patients are in critical condition, and the death cases are mostly seen in the elderly and patients with chronic basic diseases. Of course, there are also some mild cases, fever is not obvious, occasional dry cough or asthenia, clinical symptoms are mild, no obvious pneumonia, easy to be ignored. In particular, asymptomatic infections bring challenges to the prevention and control work.
03
What are the basic links in the epidemic of infectious diseases?
A: infectious source, transmission route and susceptible population are the basic conditions for the epidemic of infectious diseases. Only these three links exist at the same time and are interrelated can the epidemic process of infectious diseases be formed. Controlling the source of infection, cutting off the route of transmission and protecting the susceptible population are the basic and effective measures to control the epidemic of infectious diseases.
04
Novel coronavirus is the main transmission route of droplet transmission, and also can be transmitted through contact. How can we effectively prevent infection?
A: during the epidemic period, when going out (especially to densely populated public places), we must choose and wear masks correctly; when greeting, we should avoid physical contact such as hugging and shaking hands, and try to keep a distance of more than 1 meter from others; when coughing or sneezing, we should cover our mouth and nose with paper towels or sleeves; we should wash hands frequently and keep hands clean, which is to prevent and control the spread of pathogens The most basic, simple and effective means of broadcasting.
Novel coronavirus pneumonia patients have diarrhea and other gastrointestinal symptoms. The virus can also be detected in feces. It can lead to the existence of fecal oral transmission pathway, and further suggests that strengthening personal hygiene is an important measure to cut off the transmission route.
05
At present, novel coronavirus pneumonia is not effective. What healthy habits can help us prevent it?
A: first of all, we should enhance the awareness of health, maintain good living habits, balance diet, and maintain the normal immune function of the body.
Secondly, we should take the initiative to do a good job of health monitoring for individuals and family members. In case of fever and other suspicious symptoms, we should seek the help of professionals in time according to the condition of the disease, and under the guidance of them, we should conduct isolation observation or go to medical institutions for treatment.
In addition, we should correctly understand all kinds of emotional, physiological, thinking and behavioral stress reactions when major epidemics occur, accept information from credible sources, and establish effective psychological epidemic prevention. If there is psychological trauma that cannot be adjusted, we should accept the emergency psychological crisis intervention and psychological counseling in time.
06
If I am a student, what should I do after returning to school?
A: if you need to go back to school, you can't relax your vigilance. I suggest:
1. Before returning to school, students who have lived or traveled in high epidemic areas (such as Wuhan) are recommended to return to school after 14 days of home observation.
2. When returning to school by public transport, it is recommended that students wear masks throughout the course to reduce exposure to public goods and keep hands clean at all times.
3. After returning to school, students should monitor their body temperature and health status every day, measure their body temperature twice a day, try to reduce going out and avoid contact with other personnel; in case of close contact, they should wear masks correctly, and try to narrow the scope of activity.
07
Faced with the return of teachers and students, how should schools do a good job in prevention?
A: 1. The school should record the absence, early leave and leave of students, set up epidemic management personnel and epidemic reporting system, closely monitor the health status of students, timely identify and find suspicious symptoms among teachers and students, and cooperate with medical and health institutions to manage and disinfect close contacts.
2. Schools should try to avoid organizing large-scale collective activities. Classroom, dormitory, library, activity center, canteen, auditorium, teacher's office, toilet and other public activity areas shall be cleaned and disinfected, ventilation shall be strengthened, and necessary hand sanitizer and other sanitary articles shall be provided.
3. Strengthen the management of personnel and vehicles entering and leaving the campus, set up temporary observation points at the school gate, and monitor the temperature and symptoms of personnel entering the campus.
4. Set up a medical isolation observation point near the school, a single room for temporary placement of suspected personnel with fever, cough and epidemiological history. Pay attention to disinfection at any time and terminal disinfection.
In this vigorous battle of prevention and control of the epidemic
Everyone is a participant
As long as we master the correct protection knowledge
Practically implement all joint prevention and control measures
Strengthen confidence and work together in the same boat
Scientific prevention and control, precise policy implementation
We are sure to win the prevention and control of the epidemic
