The predominate flu continues to be the H3N2 strain — one that is poorly matched to this year’s vaccine, indicated the agency.

“While most of the viruses spreading this season are different from what is in the vaccine, vaccination can still provide protection and might reduce severe outcomes such as hospitalization and death,” wrote the agency.

A three-pronged approach for combating the flu has been suggested by the CDC:

  1. Get vaccinated
  2. Practice preventive care to help stop the spread of germs
  3. If prescribed, take antiviral medications to treat the flu
