CDC's latest weekly flu report: Still no season to speak of to date


ATLANTA — The Centers for Disease Control and Prevention on Friday issued its latest update on the influenza season to date, or rather the lack thereof. For the week ended Feb. 25, visits for influenza-like illnesses have yet to crack the national baseline of 2.4% this season.

Over the past two seasons, 2009/2010 and 2010/2011, reports of ILI activity reached levels approaching 8% and 5%, respectively, after crossing over that 2.4% threshold — an indicator that the flu season is well under way.

According to the CDC, 1.9% of patient visits reported through the U.S. Outpatient Influenza-like Illness Surveillance Network were due to influenza-like illness. ILI is defined as fever (temperature of 100°F or greater) and cough and/or sore throat.

Alabama, Missouri and Oklahoma experienced high ILI activity, and both Illinois and Kansas reported moderate activity. A total of 39 states reported minimal activity, however.
