Flu Season by Ayala Fischel, PharmD

What is Flu Season? What is it? How does it affect me?


While seasonal influenza (flu) viruses are detected year-round in the United States, flu viruses are most common during the fall and winter. The exact timing and duration of flu seasons can vary, but influenza activity often begins to increase in October. Most of the time flu activity peaks between December and February, although activity can last as late as May.

Influenza is a contagious viral disease, and it can cause mild to severe symptoms along with life-threatening complications, even in young, healthy children and adults. 

Like all other vaccines, the one for flu isn't perfect, but it cuts the risk of illness from 30% to 60% in the general population, according to the CDC (Center for Disease Control). You should get the flu vaccine before influenza begins spreading in your community. It takes about two weeks after vaccination for antibodies that protect against flu to develop in the body, so make plans to get vaccinated early in fall, before flu season begins. Currently, there are several vaccines on the market. Different vaccines are approved for different age groups. Ask your doctor or pharmacist which is best for you.
