Dr. Alicia Fry, chief of the epidemiology and prevention branch within the U.S. Centers for Disease Control and Prevention’s influenza division, cautions that “if you’ve seen one flu season, you’ve seen one flu season”—meaning the virus is unpredictable and guesses about it aren’t always accurate. “Whether it will be a severe season or a mild season, or what to expect, or what viruses might circulate—that we really just don’t know,” Fry says.
Nonetheless, there are some factors that could set up the U.S. for a more serious flu season this year, says Dr. Brandon Webb, an infectious disease specialist at Utah’s Intermountain Medical Center. Flu season severity varies quite a bit from year to year, depending on factors including immunity in the population and which influenza strain is circulating. “Individuals who get influenza the year prior probably carry over some incomplete or partial immunity,” Webb explains.
