Type A flu is the most common type of influenza. Type A influenza symptoms include respiratory symptoms like coughing and sneezing and a runny nose, as well as influenza symptoms like headache, muscle aches, and fever. Flu symptoms are similar to the symptoms of a cold, but fever is rare with a cold and common with the flu.
I heard that only Influenza type A leads to pandemics situation since type B (or C) Influenza has only one HA and NA type. I donât understand why the types B and C have only one HA and NA type when the type A has a lot of different ones. And I donât understand the link between this and the capacity of producing pandemic. Thank you
