Cough alone without fever is not necessarily Neoconiosis. The current epidemic of Neoconiosis caused by a new coronavirus infection usually has fever, dry cough, malaise, and in some cases diarrhea, and some patients can also develop respiratory distress, respiratory failure, and even shock and life-threatening conditions after a week. If the patient does not have a history of living in an infected area, and there is no history of close contact with a patient with confirmed Newcastle pneumonia, a simple cough is not considered to be Newcastle pneumonia, but may be an allergic cough, bronchitis, or pneumonia caused by a bacterial infection. If the patient has a history of living in an infected area, or has a history of close contact with a patient with neocrown pneumonia, it is recommended that the patient go to a local designated hospital for viral nucleic acid testing and chest CT, etc., to clarify the diagnosis.
