During the week of Jan. 26 through Feb. 1, 2025, flu activity remained elevated in the United States, with 43 states reporting high or very high outpatient respiratory illness activity, according to FluView, a weekly influenza surveillance report prepared by the Influenza Division of the U.S. Centers for Disease Control and Prevention.
During this week, of the 4,377 viruses reported by public health laboratories, 4,264 and 113 were influenza A and B, respectively. Of the 3,458 influenza A viruses subtyped, 53.7 percent were influenza A(H1N1)pdm09 and 46.3 percent were A(H3N2); there were no reports of A(H5). There was one reported case of human infection with an influenza A(H1N2) variant.
The proportion of outpatient visits for respiratory illness was 7.8 percent, remaining above the national baseline for the 10th consecutive week. Two percent of overall deaths were attributed to influenza. Ten pediatric deaths associated with seasonal influenza were reported, bringing the 2024-2025 season total to 57 pediatric deaths.
There have been at least 24 million influenza illnesses, 310,000 hospitalizations, and 13,000 deaths so far this influenza season.
“CDC recommends that everyone ages 6 months and older get an annual influenza vaccine,” according to a statement from the agency. “There are prescription flu antiviral drugs that can treat flu illness; those should be started as early as possible and are especially important for patients at higher risk for severe illness.”
