The earliest symptoms of influenza

Simple influenza often suddenly onset, cold and high fever, body temperature up to 39 ~ 40 ℃, with headache, muscle and joint pain, extreme fatigue, loss of appetite and other systemic symptoms, often throat pain, dry cough, nasal congestion, runny nose, sternal discomfort.

After 3-4 days of onset, the body temperature gradually subsides and the general symptoms improve. However, it usually takes 1-2 weeks for cough and physical recovery. Mild influenza is similar to common cold. The symptoms are mild and can recover in 2-3 days.

Pneumonia type influenza is actually complicated with influenza virus pneumonia, which is more common in the elderly, children and people with original cardiopulmonary diseases. The main manifestations were persistent high fever, severe cough, hemoptysis or purulent sputum, shortness of breath, cyanosis, and moist rales in the lungs. Chest X-ray showed scattered flocculent shadows in both lungs. No pathogenic bacteria were found in sputum culture, and influenza virus could be isolated. May die of respiratory and circulatory failure.

In addition to fever, gastrointestinal influenza is characterized by vomiting, abdominal pain and diarrhea. It can recover in 2-3 days. Toxic influenza presents severe symptoms such as high fever, shock, respiratory failure, central nervous system damage and disseminated intravascular coagulation (DIC), with high mortality.
