What Are the Differences Between Influenza A and Common Flu?

General influenza typically refers to common influenza, and influenza A can be distinguished from general influenza through etiology, infectivity, and speed of transmission.

1. Etiology: Influenza A is usually caused by influenza A virus infection, while there are multiple viruses that can cause general influenza, with more complex virus classification.

2. Infectivity: Influenza A is highly infectious and generally susceptible, often being a zoonotic disease. Apart from influenza A, the infectivity of general influenza is generally weaker.

3. Speed of Transmission: Generally, the infection speed of influenza A is faster, occurring within 1 to 7 days after infection. Apart from influenza A, other general influenzas generally have a slower infection speed with a longer incubation period after infection.

They can also be distinguished through clinical symptoms. When the body experiences discomfort, one should promptly visit a formal hospital and identify the disease through systematic examination under the guidance of a doctor to avoid delaying treatment.
