Answer:
There are three types of influenza viruses: A, B, and C. Major epidemics are caused by A and B, and it is usually these two varieties that cause the flu. They have a diameter of about 100 nanometers, making them a medium sized virus. They have two kinds of spiky structures on their surface. One kind is a glycoprotein called hemagglutinin (HA), which is needed for the virus to bond to cells in the throat and bronchial tube and cause an infection, and the other is a glycoprotein called neuraminidase (NA), which has the function of breaking the linkages between HA and the cell
