Influenza A refers to the illness caused by the influenza A virus. It is a common viral disease. Symptoms of influenza A vary widely, with common ones including fever, headache, muscle pain, fatigue, and coughing; symptoms may differ among people of different age groups. Sometimes, the influenza A virus can lead to upper respiratory tract infections such as bronchitis, pneumonia, and bacterial pharyngitis. To prevent influenza A, protective measures should be taken, personal hygiene should be carefully maintained, and timely vaccination is recommended.
