Influenza is an acute respiratory infectious disease caused by influenza virus. The symptoms of systemic poisoning are obvious, such as high fever, headache, muscle aches and weakness, while the respiratory symptoms are mild, and cough and expectoration are rare.
In addition, pneumonia and influenza can be distinguished by virus detection of respiratory secretions. Pneumonia patients were positive for virus detection, and influenza patients were negative for virus nucleic acid detection. Distinguish influenza and virus from the following aspects:
Clinical symptoms: The general symptoms of influenza are very serious, and there will be muscle pain and fatigue. The typical manifestations of pneumonia are dry cough, fatigue, chest tightness, asthma and dyspnea. Severe patients will have respiratory failure, cyanosis of skin and mucosa, headache, dizziness and even coma after one week.
Etiology: Influenza is caused by influenza virus, while pneumonia is a highly contagious disease caused by a new virus invading human body.
Infection generally refers to a new virus infection, and influenza and virus infection can be distinguished from their clinical manifestations. Typical symptoms of influenza include general fatigue, muscle pain, fever and headache. However, some patients with viral infection may have no obvious symptoms, and some patients may have symptoms such as dry cough, fatigue, shortness of breath and difficulty breathing. Severe patients will have respiratory failure after one week. In addition, it can also be distinguished by nucleic acid detection.
