2. What Are the Symptoms of Flu B?
Flu B can cause a myriad of symptoms. One of the most common signs is a fever. This virus can cause a fever spike of as high as 106° F, although fevers tend to be lower in adults than in children. It is common for a fever to last up to three days. Other common body symptoms include body aches, chills, weakness and fatigue. Stomach symptoms are also common with flu B. These include appetite loss, abdominal pain, nausea and vomiting.
The flu virus also causes respiratory infection, and the symptoms of this tend to appear after the fever diminishes. People with the flu often complain of a runny nose, congestion, cough and sore throat. Most of the respiratory symptoms last about a week, although the cough may last longer.
