While you normally only hear about a surge of flu cases during the deep winter months, it’s still early fall and the U.S. is already seeing flu at higher-than-usual rates. A recent report from the Centers for Disease Control and Prevention (CDC) notes that seasonal flu activity is “increasing” in many parts of the country, though it is still generally low. Based on the latest data, 3.6% of Americans tested for a respiratory issue were also positive for the flu.
Here's what you need to know. Meet the experts: Asefeh Faraz Covelli, PhD, APRN, researcher and associate professor at The George Washington University School of Nursing and Thomas Russo, MD, professor and chief of infectious disease at the University at Buffalo in New York The flu doesn't hit the country at the same level, at the same time. Right now, for example, the CDC points out that the highest flu activity is happening on the West Coast.
California's test positivity rate for influenza currently sits at 8.8 percent, based on state data, while Alaska's public health department noted that flu cases started to "increase noticeably" in mid-August. That may be more immune-evasive than other strains, leading to the rise in early infections, Dr. But Covelli includes this important caveat: “An earlier start doesn't necessarily mean the flu is stronger.” Flu viruses change every year, and some of those changes may make it easier for the virus to spread in people who have some level of immunity already.
"Researchers are watching the strains circulating this year, but it's too early to know whether these changes will make this flu season more severe," she says. If you’re worried you have the flu, keep the following in mind. Flu symptoms don't really change from year to year, and these are the biggest ones to be aware of, per the CDC: Public health agencies usually recommend getting vaccinated by Halloween.
But given the season's early start, healthcare providers say you're fine to get the vaccine now. Also, while it's easy to assume an early start to flu season means it might also end sooner, that's not guaranteed.
