Influenza, more commonly known as “the flu,” is a highly-contagious respiratory virus. This virus can affect the nose, throat and lungs. Its symptoms can range from mild (little to no symptoms) to severe. This is why it’s very important to get a flu vaccine, which can help prevent the flu.
While the flu is a year-round virus, it’s more common during what is known as “flu season,” which is in the fall and winter. It generally starts around October, peaks in February, and can last until the Spring.
