Dry cough, nasal congestion, runny nose, post-sternal discomfort, etc. Facial flushing, conjunctival hyperemia. Some are characterized by vomiting, abdominal pain, and diarrhea, and are common in children infected with influenza B. The course of the disease is self-limiting in uncomplicated patients, more than 3 to 4 days after the onset of the disease, the body temperature gradually subsides, and the systemic symptoms improve, but it usually takes 1 to 2 weeks for cough and physical recovery. Pneumonia is the most common complication of influenza. Other complications include nervous system damage, heart damage, myositis, rhabdomyolysis syndrome, and septic shock.

At present, there is insufficient clinical data on the symptoms of pneumonia caused by the new coronavirus. According to existing case data, pneumonia caused by new coronavirus infection is mainly manifested by fever, fatigue, and dry cough. A small number of patients are accompanied by nasal congestion, runny nose, diarrhea and other upper respiratory and digestive tract symptoms. Severe cases often have difficulty breathing after 1 week, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, difficult to correct metabolic acidosis and coagulopathy. It is worth noting that severe and critically ill patients may have moderate to low fever during the course of their illness, or even no obvious fever. Some patients only showed low fever, mild fatigue, etc., without pneumonia, and recovered after 1 week. A small number of infected people have no obvious clinical symptoms and only test positive. Judging from the status of the currently admitted cases, most patients have a good prognosis, children's cases have relatively mild symptoms, and a few patients are in critical condition. Deaths are more common in the elderly and those with chronic underlying diseases.
