Cold and flu season usually ranges from October to May. Those infected may wake up with fever, chills, and aches and pains, which can hinder their ability to work or care for their families. If you've received a flu vaccination in the last few years, you might think you're safe from influenza. Unfortunately, because of mutations within the virus year after year, this isn't always the case. To save yourself a trip to your local urgent care center for symptom relief, the guide below explains this evolution and how to protect your health. 

What Are the Different Types of Influenza?

While there are four different types of the flu virus—influenza A, B, C, and D—A and B are the most common causes of seasonal infections. 

Influenza A is found in many species, including humans, birds, and pigs. Because it can survive in a variety of hosts and can mutate easily over short periods, Influenza A viruses are highly diverse, making them difficult to track and treat. As a result, Influenza A is capable of reaching pandemic levels and is estimated to account for 75% of confirmed flu infections seasonally.

Comparatively, Influenza B is typically only found in humans and makes up for just 25% of confirmed flu infections each year, as the virus mutates much more slowly than influenza A. Influenza B is much more prevalent near the end of flu season when cases of Influenza A have begun to decrease. 

How Do Influenza Viruses Change?

Both Influenza types A and B continually undergo a process called antigenic drift, or small mutations within the virus—mainly to its surface proteins, HA (hemagglutinin) and NA (neuraminidase). Because of this new packaging, the virus can slip past defenses put in place by last year’s flu vaccine.

In response, researchers spend time each year predicting the latest changes and creating new immunizations to face these new threats.

How Can I Prevent the Flu?

While both Influenza A and B are extremely contagious, there are ways to prevent the spread and contraction of both. The first step is getting your flu vaccine at a doctor’s office or an urgent care center each year.

Influenza can spread from up to six feet away through coughing and sneezing. It can also be contracted by touching an infected surface. Regularly disinfect surfaces in your home or office, wash your hands, and avoid touching your face, especially if you have been in a public space or in contact with someone who has influenza.
