1. What symptoms may appear to be infected with the new coronavirus(COVID-19)?
The general symptoms of new coronavirus infection are: fever, fatigue, dry cough, and dyspnea gradually appear; some patients have mild onset symptoms, and may not even have obvious fever.

severe symptoms: acute respiratory distress syndrome, septic shock, difficult to correct metabolic acidosis, coagulation dysfunction. Judging from the current cases, most patients have a good prognosis, and a few patients are critically ill and even die.

onset of symptoms in addition to the above, there may be the onset of symptoms "atypical", for example:
(1) only digestive symptoms as initial manifestations: such as mild anorexia, fatigue, poor spirit, nausea Vomiting, diarrhea, etc .;
(2) First manifestations with neurological symptoms: such as headache;
(3) First manifestations with cardiovascular symptoms: such as palpitation, chest tightness, etc.
(4) With Ophthalmic symptoms are the first manifestations: such as conjunctivitis;
(5) Only mild sore limbs or lower back muscles.
2. If clinical symptoms such as fever, fatigue, and dry cough appear, does it mean infection with new coronary pneumonia?
Many respiratory diseases are manifested by symptoms such as fever, fatigue, and dry cough. Whether or not the new coronavirus is infected also needs to be determined comprehensively by confirming whether the patient has visited the epidemic area before the onset of the disease, has been exposed to suspicious or confirmed cases, and the results of laboratory tests.
3. Dry cough is one of the symptoms, so what is the difference between dry cough and cough?
The main difference between a dry cough and a cough is the presence of sputum.

dry cough refers to cough without phlegm. A common cold and acute bronchitis can also cause dry cough, and some respiratory infections are also common, such as acute sinusitis, acute rhinitis, acute tonsillitis, acute pharyngitis, and acute episodes of chronic bronchitis. In addition, inhaling some irritating gases and dust can also induce acute dry cough.

cough is a protective response mechanism of the respiratory tract, it can be cleared by coughing and respiratory tract secretions harmful factor. Sputum is formed when secretions or harmful factors in the airways are expelled from the body with the action of a cough. Coughing and sputum usually means that the respiratory tract is irritated or has a disease.
4. What symptoms need to be treated in time?
If you have symptoms such as fever, fatigue, muscle aches, cough, sputum, shortness of breath, diarrhea, conjunctival congestion, etc., you should seek medical treatment in time, and tell the doctor two weeks before the onset of travel or contact history to make a rapid diagnosis.
5. What is the difference between the new coronavirus pneumonia and the symptoms of flu and common cold?
New coronavirus pneumonia is mainly manifested by fever, fatigue, and dry cough. A few patients are accompanied by upper respiratory and digestive symptoms such as nasal congestion, runny nose, and diarrhea. May be accompanied by pneumonia, but early pneumonia may not have fever, only chills and respiratory infection symptoms, but CT will show pneumonia.

and more severe cases difficulty in breathing and / or hypoxemia after one week, to quickly progress to severe acute respiratory distress syndrome, septic shock, metabolic acidosis and difficult to correct the coagulation obstacle.

is worth noting that, in the course of critically ill patients can be expressed as body temperature fever, even without significant fever.

Some patients showed only mild fever, mild fatigue, no pneumonia, most recovery after 1 week. A few infected people have no obvious clinical symptoms and only test positive. Judging from the current cases, most patients have a good prognosis, children's cases are relatively mild, and a few patients are critically ill. Deaths are more common in the elderly and those with chronic underlying diseases.
