The initial manifestation of new coronavirus pneumonia is not specific, with fever, dry cough and malaise as the main symptoms, and some patients have no obvious symptoms, and the manifestation varies with different clinical subtypes. The full name of new coronavirus pneumonia is novel coronavirus pneumonia, which is a kind of lung inflammation caused by coronavirus. It is highly contagious, and the source of infection is mainly patients infected with the new coronavirus and asymptomatic infected people, and the transmission route is mainly the respiratory tract and close contact transmission. China is still in the epidemic period of new coronavirus pneumonia. There are usually no obvious signs before the onset of neocoronavirus pneumonia. In the early stage of infection, a small number of patients may not show any symptoms, and most of the patients will show symptoms such as fever, dry cough, and fatigue. In addition, the symptoms of infection may vary from person to person. Infected persons may also experience muscle aches and pains, chest pains and tightness in the chest, throat discomfort, nasal congestion and runny nose, abdominal pain and diarrhea, and loss of sense of taste. However, all of the above symptoms lack specificity and may also occur in patients with common colds, so it is difficult for patients to determine on their own whether they are infected with New Crown. It is recommended that after the occurrence of the above symptoms, you should seriously recall your own epidemiological contact history, and go to the fever clinic of the designated medical institution as soon as possible for relevant examinations to make a clear diagnosis.
