What is Influenza B? Symptoms, treatment, and prevention

Influenza B is a viral infection that affects the respiratory system. It is caused by the influenza B virus and is highly contagious. The symptoms of influenza B are similar to those of the flu and may include:

  • Fever
  • Body aches
  • Headache
  • Fatigue
  • Sore throat
  • Runny or stuffy nose
  • Cough

Influenza B can be treated with antiviral medications, which can help to reduce the severity and duration of symptoms. These medications are most effective when started within the first 48 hours of symptom onset. In addition, over-the-counter medications such as pain relievers, decongestants, and cough suppressants can help to relieve symptoms.

Prevention is the best way to avoid getting influenza B. The most effective way to prevent the flu is to get an annual flu vaccine. The flu vaccine is recommended for everyone over the age of 6 months and is especially important for those at high risk for complications from the flu, including young children, pregnant women, older adults, and those with certain medical conditions. Other preventive measures include washing your hands frequently, avoiding close contact with people who are sick, covering your mouth and nose when coughing or sneezing, and staying home from work or school if you are sick.
