What Is the Difference Between Influenza A and Influenza B?

We are in the middle of February, so we should be done talking about the flu virus, right? Wrong!

Unfortunately, we are in the middle of what is known as a “double-barreled” flu season, which means that two outbreaks of the flu are overlapping each other.

Because of that, your risk of getting the flu increases—and our team at AFC Urgent Care Southcenter wants to arm you with even more information about the flu. Read on as we take a look at influenza A and B.

What Is Influenza A?

When it comes to influenza type A, there are many different strains of this type of flu, which is why it is known to cause outbreaks across the United States.

In addition, because this type of flu is always changing and mutating, it can cause new strains to form with each new flu season, which is why it is important for people to receive a flu shot on an annual basis.

Symptoms of Influenza A

  • Headache
  • Fatigue
  • Chills
  • Body aches
  • Coughing
  • Runny or stuffy nose
  • Sneezing
  • Sore throat
  • Fever

What Is Influenza Type B?

Although influenza type B causes similar, sometimes severe symptoms to influenza type A, it is not as common.

Unlike influenza type A, this type of flu changes slowly, which reduces the risk of it becoming a widespread outbreak like type A.

Ways to Prevent the Flu

  • Get a flu shot if you haven’t already.
  • Wash your hands frequently with soap and water.
  • Avoid large crowds during flu season.
  • Don’t touch your face with unwashed hands.
  • Disinfect commonly touched surfaces often.
