The difference between influenza A and common cold is mainly reflected in the different pathogens of infection, different clinical symptoms and different treatment methods. 1. Different pathogens: Influenza A is caused by influenza A virus infection; while common cold may be caused by viruses such as rhinovirus, adenovirus, etc., or may be related to bacterial infection. 2. Different clinical symptoms: Although the clinical symptoms of influenza A and common cold are sometimes very similar, there are subtle differences between the two. For example, patients with influenza A are prone to high fever, headache, muscle aches and pains are more prominent; while patients with the common cold generally do not have a fever or only a low fever, runny nose, sneezing and coughing and other related manifestations are more pronounced than those of influenza A. 3. Different treatments: in addition to symptomatic treatment, patients with influenza A also need to be treated with antiviral drugs such as oseltamivir phosphate granules; whereas common colds generally require only symptomatic treatment and do not need antiviral treatment. Influenza A and the common cold may also have other differences, should be combined with epidemiological history, influenza antigen and other related tests to determine the synthesis, and timely access to medical care, the use of medication should be under the guidance of a doctor, should avoid self-medication.
