For the week ended Jan. 19, flu incidence was predominant in the central United States and picking up across the West Coast. According to data provided through the U.S. Outpatient Influenza-like Illness Surveillance Network, 4.3% of patient visits reported through the network were due to influenza-like illness, above the national baseline of 2.2%.
At this time last year, the conversation was all about the flu season that never materialized. Only one week in January last year did flu-like incidence rise above the 2.2% national baseline, and then only slightly. So cough-cold and flu comparisons across the front-end and pharmacy were both projected to be double-digit positive if even there were a moderate flu season this year.
