Consumers hoping for a healthier, wealthier 2015 may have a tough time with the former, at least—because flu season has arrived with a vengeance.
The current outbreak is shaping up to be a rough one. But there are still steps you can take to limit your chance of getting sick.
Puerto Rico and 22 states are experiencing high influenza-like illness activity, according to the latest report from the Centers for Disease Control and Prevention. That's up from 13 states the previous week.
"It's definitely in full force," said Dr. Michael Jhung, a medical officer for the CDC's influenza division.
The virus that's predominant this year, H3N2, has also been the major culprit in other severe flu seasons. And it's a strain that's not covered by this year's flu vaccine.
"We usually do a good job" predicting strains for the vaccine, said Dr. Jhung. "This year, we missed a bit. The vaccine may not work as well."
Still, experts agree a flu shot is your best bet. "There's zero harm in getting the vaccine," said Dr. Davis Liu, a family physician and the author of "The Thrifty Patient." H3N2 isn't the only game in town, and this season's vaccines protect against other strains, he said.
Although it takes up to two weeks to build up antibodies post-vaccination, it's still not too late. Flu season typically peaks in January or February, but can linger well into the spring. There's an added bonus: For most patients, getting vaccinated is free.
