Type B influenza shares many of the same symptoms as type A and type C flu. The illness will develop quickly, and symptoms depend on the person's immunity and the type of flu they contract. Many people with type B flu experience a variety of symptoms such as sudden fever with a temperature of 100 degrees Fahrenheit or higher, but not everyone with the flu will have a high temperature. Other symptoms include a chesty cough, sore throat, a runny or stuffy nose, an aching body, headaches, fatigue, loss of appetite, diarrhea, nausea, and vomiting.
