1. What are the symptoms that may be infected with the new coronavirus?

The general symptoms of the new coronavirus infection are fever, fatigue, dry cough, and gradually dyspnea; some patients have mild onset symptoms, even no obvious fever.

Severe symptoms include: acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction. From the current situation of the cases, most of the patients have a good prognosis, and a few of them are critically ill or even dead.

In addition to the above symptoms, there may be "atypical" symptoms, such as:

(1) The first symptoms were digestive system symptoms, such as mild anorexia, asthenia, poor spirit, nausea and vomiting, diarrhea, etc;

(2) The first manifestation was nervous system symptoms, such as headache;

(3) The first manifestation was cardiovascular system symptoms, such as palpitation, chest distress, etc;

(4) The first manifestation was ophthalmic symptoms, such as conjunctivitis;

(5) Only mild muscle soreness in the extremities or back.

2. If there are fever, fatigue, dry cough and other clinical manifestations, does it mean infection?

Many respiratory diseases are characterized by fever, fatigue, dry cough and other symptoms. It is necessary for doctors to make a comprehensive judgment on whether they have been to the epidemic area before the onset of the disease, whether they have contacted suspected or confirmed cases, and the results of laboratory tests.

3. Dry cough is one of the symptoms. What's the difference between dry cough and cough?

The main difference between dry cough and cough is whether there is phlegm.

Dry cough refers to a cough without phlegm or with little amount of phlegm. Common cold and acute bronchitis can also cause dry cough, and some respiratory infectious diseases are also common, such as acute sinusitis, acute rhinitis, acute tonsillitis, acute pharyngitis, and acute attack of chronic bronchitis. In addition, inhalation of some irritant gases, dust, etc. can also induce acute dry cough.

Cough is a protective reaction mechanism of respiratory tract, through which secretion and harmful factors in respiratory tract can be removed. Expectoration occurs when secretions or harmful factors in the airway are expelled with the cough. Coughing and expectoration usually means that the respiratory tract is stimulated or has some disease.

4. What symptoms need to be treated in time?

In case of fever, fatigue, muscle ache, cough, expectoration, shortness of breath, diarrhea, conjunctival congestion and other symptoms, the doctor should be timely consulted, and the travel history of two weeks before the onset of the disease should be informed so that the doctor can make a quick judgment.

5. What department do you go to see when you have symptoms?

For the patients with fever, fatigue and cough, after arriving at the hospital, the nurse will first measure the temperature and guide them to the fever clinic. The clinic doctor will ask if you have been to the epidemic area within 2 weeks and if you have been exposed to suspected or confirmed cases. In case of suspected pneumonia, the doctor will send your throat swab, sputum and other samples to the Centers for Disease Control and prevention or qualified hospital laboratories for new coronavirus detection. If the test result is positive, it can be confirmed.

6. What should we do if we suspect that people around us are infected with new coronavirus?

If it is suspected that the surrounding people are infected with the new coronavirus, they should first wear masks and keep a distance of more than 1 meter from each other to avoid close communication with each other, and then suggest that the other party wear masks and go to the fever clinic of the nearest designated hospital in time for treatment.

7. What is the difference between the symptoms of new coronavirus pneumonia, influenza and common cold?

The main manifestations of new-type coronavirus pneumonia are fever, fatigue and dry cough. A few patients have upper respiratory tract and digestive tract symptoms such as nasal obstruction, runny nose and diarrhea. It may be accompanied by pneumonia, but early pneumonia may not have fever, only chills and respiratory tract infection symptoms, but CT will show pneumonia. Most of the severe cases developed dyspnea or / and hypoxemia one week later. The severe cases developed rapidly into acute respiratory distress syndrome, septic shock, metabolic acidosis and coagulation dysfunction which were difficult to correct. It should be noted that the course of severe and critical patients can be moderate to low fever, or even no obvious fever. Mild patients only showed low fever and slight asthenia, no pneumonia, mostly recovered after one week. A small number of infected patients had no obvious clinical symptoms, only positive. From the current situation of the cases, most of the patients have a good prognosis, children are relatively light, and a few patients are in critical condition. The death cases were mostly seen in the elderly and chronic basic diseases.

The main symptoms of influenza are fever, headache, muscle pain and general malaise. The body temperature can reach 39-40 ℃, with chills and chills. Most of them are accompanied by general symptoms such as muscle and joint pain, fatigue, anorexia, etc., often with sore throat, dry cough, nasal congestion, runny nose, and post sternal malaise. The face is flushed and the conjunctiva is congested. Some of them are characterized by vomiting, abdominal pain and diarrhea. The course of disease was self limited in the patients without complications. The body temperature returned to normal 3-4 days after the extra onset, and the general symptoms improved. However, the recovery of cough and physical strength usually took 1-2 weeks. Pneumonia is the most common complication. Other complications include nervous system injury, myocardial damage, myositis, rhabdomyolysis syndrome and septic shock.

The common cold is characterized by stuffy nose and runny nose. Most patients have mild symptoms and generally do not cause pneumonia.
