At present, the new type of pneumonia refers to the new type of coronavirus infection. The symptoms of the disease mainly include fever, fatigue, and dry cough. A few patients are accompanied by nasal congestion, runny nose, sore throat, diarrhea and other symptoms. According to the latest research results, the incubation period of new pneumonia is up to 24 days, mostly 3-7 days. Mild patients only present with low fever, mild fatigue, etc., without symptoms of pneumonia or dry cough.
Critically ill patients often develop dyspnea and/or hypoxemia one week after the onset of onset, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, difficult to correct metabolic acidosis , and coagulopathy, etc. . Severe and critically ill patients may have moderate to low fever during the course of their illness, or even no obvious fever.
In addition to the above symptoms, the disease may also be atypical. For example, only the digestive system symptoms are the main manifestations, such as mild loss of appetite, fatigue, poor spirits, nausea and vomiting, diarrhea, etc.; the first symptom is nervous system headache; Ophthalmological symptoms are the first manifestations, such as conjunctival hyperemia, increased ocular secretions, etc.; or only mild limbs or low back muscle soreness.
At the same time, the symptoms of the disease are similar to those caused by other known viruses such as influenza virus , parainfluenza virus, adenovirus, respiratory syncytial virus, rhinovirus, etc., so pay attention to distinguish them.
