The common cold can be caused by a variety of viruses, the most common being rhinovirus, while influenza is caused by the influenza virus. The main manifestations of both the common cold and the influenza include systemic symptoms and respiratory symptoms, the difference being that the systemic symptoms of the influenza are more severe, including fever, body aches, fatigue, loss of appetite and so on. The common cold has more localized respiratory symptoms, such as sore throat, cough, runny nose, sneezing, etc. In terms of treatment, the common cold does not require additional treatment, and if the symptoms are heavy you can use medicines that reduce the symptoms. Early in the course of influenza, it will heal faster if antiviral treatment is administered.
