ATLANTA — For the week ended Feb. 9, influenza activity decreased to 3.2% — still above the baseline of 2.2%, but an indicator this year's flu season is on its way out. 

Eleven states and New York City were still experiencing high influenza-like illness activity, while 10 states reported moderate activity.

ATLANTA — The flu epidemic is in full swing in the West and across the Southwest, as just about every state west of the Mississippi through to California is in the red on the Centers for Disease Control and Prevention weekly FluView for the week ended Jan. 26. 

As expected, many of those living in areas with high influenza-like illness activity were visiting their local drug stores for symptomatic relief. Drug store front-end sales were up 7.4% for the four weeks ended Jan. 26, according to reports citing Nielsen data. 

ATLANTA — If the flu were a storm cloud, the influenza virus is hovering over America's Bread Basket on its way to the Southwest, according to data provided through the U.S. Outpatient Influenza-like Illness Surveillance Network. 

The Centers for Disease Control and Prevention on Friday reported that 4.3% of patient visits reported through ILINet were due to influenza-like illness, above the national baseline of 2.2%.

ATLANTA — The incidence of influenza continued on an upward trajectory heading into the Christmas holiday, the Centers for Disease Control and Prevention reported Friday. Nationwide for the week ending Dec. 22, 4.2% of patient visits reported through the U.S. Outpatient Influenza-like Illness Surveillance Network were due to influenza-like illness, above the national baseline of 2.2%. 

It was the cough, cold and flu season that wasn’t. The percentage of patient visits on account of influenza-like illnesses never eclipsed the 2.4% baseline that typically marks the beginning and end of a flu season. According to the Centers for Disease Control and Prevention, the closest the 2011-2012 flu season came to materializing was the week ended March 17, when 2.384% of all office visits were attributed to ILI symptoms nationwide. 


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.

DEERFIELD, Ill. — The typical flu season always coincides with the busiest travel period of the year, and last season that spelled trouble for more than 3 million U.S. vacationers whose trips were interrupted by flu-related illness, according to the "Walgreens Flu Impact Report" released Tuesday.

The findings in part two of the survey examining the effects of influenza on people's everyday lives, released today, showed how the flu affected Americans' vacations, holidays, social engagements, sporting events and more.

By all accounts, it’s been a very busy first half of the season for cough-cold manufacturers, even though the 52-week comparable period is only showing a 1.9% lift in overall sales across food, drug and mass (minus Walmart) for the period ended Jan. 24, according to Information Resources Inc. data. For the 2009-2010 season, the weekly percentage of outpatient visits for influenza-like illness peaked at the end of October 2009 at 7.7%, the Centers for Disease Control and Prevention reported. That peak was higher than the three previous influenza seasons as reported by the U.S.
