Recently, pneumonia outbreaks of novel coronavirus infections have been occurring in several regions and countries, including Wuhan City, Hubei Province, and reports of pneumonia outbreaks of novel coronavirus infections have been dominating news headlines and even turning on cell phone domination mode. In response, Party and State leader General Secretary Xi Jinping also gave important instructions on novel coronavirus pneumonia, and the National Health and Wellness Commission decided to include novel coronavirus-infected pneumonia in the management of legal infectious diseases category B and take preventive and control measures for category A infectious diseases. With the joint efforts of health prevention departments, hospital medical staff and government agencies, the understanding of novel coronavirus-infected pneumonia is gradually deepening. Respiratory attending physician Hua Minglei reminded the public, in the face of this new coronavirus pneumonia do not panic, the most important thing is to take the right preventive measures, blocking droplet and contact transmission is the main way to prevent and control respiratory infections. A, preventive measures: 1, go to public places to wear a mask According to current information, the new coronavirus can be human-to-human transmission, so go out with a mask to protect themselves and protect others. The three types of masks commonly found in the market are as follows: medical surgical mask: can block 70% of bacteria, if you go to public places and do not contact with patients, wearing a medical surgical mask is enough; medical protective mask (N95 mask): can block 95% of bacteria, if you will contact with patients, you should wear an anti-biological N95 mask; ordinary cotton gauze mask: can block 36% of bacteria. The above data show that medical protective masks (N95 masks) block the highest proportion of bacteria, up to 95%, but the prevention of new coronavirus does not necessarily have to use such masks, general masks are also able to block most of the droplets with viruses into the respiratory tract, the prevention of new coronavirus, wearing a mask is still useful. 2, wash your hands often after meals, after going out to home, after touching garbage, after touching animals, remember to wash your hands. When washing your hands, be careful to wash your hands with running water and use soap (soap), rubbing for no less than 15 seconds. Pay attention to protection when you go out, try your hands not to touch your face, not to rub your eyes, and not to take food directly. Maintain basic hand hygiene and respiratory hygiene, avoid close contact with people who have fever and cough and sneeze. 3. Avoid contact with wild animals Cook meat and eggs thoroughly and avoid eating or drinking undercooked animal products. Try to avoid contact with wild animals or eating wild game, and avoid going to live poultry markets or farms. Pay attention to personal hygiene When sneezing or coughing, do not cover your mouth and nose directly with your hands. The proper way is to use tissues or bend your elbows to cover your mouth and nose. Used tissues should be discarded in the hazardous waste bin, and then wash your hands thoroughly. 4. Be alert to abnormal symptoms and seek prompt medical attention If you have the following symptoms, please seek prompt medical attention at a hospital fever clinic: coughing, coughing phlegm; fever (temperature ≥38℃); difficulty in breathing during daily activities or rest; pain when taking deep breaths; rapid heartbeat; sudden deterioration and chills after getting better from a cold or flu. Note that if you are unwell, please try to stay at home and do not go out to play. If you experience any of the above symptoms, please wear a mask and go to the hospital promptly. If it is not convenient to go to the hospital, you can contact the local regular public hospital and inform the doctor of the symptoms. Second, look at the epidemic rationally and do not be overly alarmed. From the current epidemic report, the number of people who have developed the disease is already quite high, and most of them are still mild or moderate patients. The number of deaths is still relatively small. At present, from the statistics, it has a lower death rate than H7N9 and SARS in 2002. From the current incidence, all people are susceptible, the elderly, immunocompromised, and those with chronic diseases are more likely to be infected, or become seriously ill. Therefore, poor immune function, the elderly, etc., should pay more attention to prevention. At present, there is no specific antiviral drug for novel coronavirus, treatment is mainly symptomatic, at least, there is no clinical evidence that the anti-influenza A drug oseltamivir is effective in the treatment of novel coronavirus, do not take it blindly. Although, the number of new cases is increasing every day, it is not the same as it was 17 years ago when SARS was introduced. Firstly, a comprehensive epidemic prevention and control system has been established from the central to the local governments (from the central to the local CDCs, which can realize epidemic network monitoring and direct reporting), which can effectively monitor and prevent the spread of the disease. Secondly, for the new coronavirus infection pneumonia, even for severe patients, we have experienced SARS, H7N9 avian influenza and H1N1 influenza A. We have accumulated a lot of experience in the treatment of viral infection-related pneumonia, including pharmacological treatment (more rational and rational application of hormones), mechanical ventilation respiratory support (clinical case studies have proved that for ARDS patients with small tidal volume, prone position Third, new technologies and new equipment are being promoted and applied (especially extracorporeal membrane oxygenation ECMO technology), and as long as patients are treated promptly and effectively, the morbidity and mortality rate will not be as high as before. In conclusion, the new coronavirus infection pneumonia is preventable and treatable, we should look at it rationally, do not believe in rumors and untrue information on the Internet, and blindly follow the trend. We believe that the relevant government agencies and departments will make specific countermeasures, believe in the efforts and dedication of medical personnel, face the information on the Internet rumors, handle them calmly, analyze them rationally, respond calmly, and believe that in the coming spring, the storm has passed and everything will be fine.
