Why do I keep getting the flu over and over?

It is possible to get sick regularly when the immune system is not functioning correctly. The reason for this is that the body is unable to fight off germs, such as bacteria, properly. If an infection occurs, it can take longer than usual to recover.

Is the Flu A or B worse?

Type A influenza is generally considered worse than type B influenza. This is because the symptoms are often more severe in type A influenza than in type B influenza.
