Based on the current epidemiologic investigation, the incubation period of the new type of pneumonia is usually 3-7 days, and the longest period does not exceed 14 days. Typical Symptoms of New Pneumonia New Pneumonia is mainly characterized by fever, malaise and dry cough, and a few patients are accompanied by nasal congestion, runny nose, diarrhea and other symptoms. Mild patients only have symptoms similar to the flu, while severe cases mostly have respiratory difficulties after a week, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis and coagulation dysfunction. It is worth noting that patients with severe and critical illnesses may have low to moderate fever, or even no apparent fever during the course of the disease. Some patients only show low fever, slight fatigue, etc., without pneumonia, and most of them recover after 1 week. From the current admissions, most patients have a good prognosis, children’s cases are relatively mild, a few cardiopulmonary diseases, immunocompromised people, infants and the elderly patients are more serious, and deaths are mostly seen in the elderly and people with chronic underlying diseases. Atypical Symptoms of New Pneumonia In addition to the above symptoms, there may also be “atypical” symptoms, such as: (1) only digestive symptoms as the first manifestation: such as mild nausea, fatigue, poor mental health, nausea and vomiting, diarrhea, etc.; (2) to the neurological symptoms as the first manifestation: such as headache; (3) to the cardiovascular symptoms as the first manifestation: such as panic attacks, chest pains and heartburn; (4) to the cardiovascular symptoms as the first manifestation. (3) The first manifestation of cardiovascular system symptoms: such as panic, chest tightness, etc.; (4) The first manifestation of ophthalmologic symptoms: such as conjunctivitis; (5) Only mild limb or back muscle pain. What to do if you have fever symptoms It is important to go to a fever clinic and take personal precautions when you have fever symptoms. Fever is still a typical symptom of novel coronavirus infection, so don’t take any chances and don’t wait at home. This is because if it is really a new coronavirus infection, there is a 20% chance that the new pneumonia will develop into a serious illness, and by the time you miss the best time to save your life, it will be too late. Response to the epidemic should be early detection and early isolation, these two are the most primitive and effective way.
