The main difference between type A and type B influenza lies in the causative viruses. Type A influenza is caused by infection with the influenza A virus, while type B influenza results from infection with the influenza B virus. Additionally, type A influenza is generally more contagious, prone to large-scale outbreaks, and may lead to more severe symptoms and a higher mortality rate; in contrast, type B influenza is less contagious, typically occurring in smaller clusters or sporadically, with milder symptoms. Regardless of which type of influenza one contracts, prompt medical attention and appropriate treatment measures are essential.
