The CDC said seasonal influenza activity remains elevated nationwide, though it has decreased or remained stable for two consecutive weeks.

Influenza A (H3N2) viruses have been the most commonly reported strains circulating this season, the agency noted.

For the week ending January 10, the CDC reported 15 influenza-associated pediatric deaths, bringing the total number of flu-related deaths among children this season to 32.

The CDC said 90 percent of reported pediatric deaths this season have occurred in children who were not fully vaccinated against influenza.

In the United States, the flu season usually occurs in fall and winter, with peak activity typically between December and February, according to the agency.

The CDC continues to urge everyone aged six months and older who has not yet received a flu vaccine this season to get vaccinated as soon as possible.
