The 2012-2013 flu season in the United States was among the most severe in more than a decade, with 2 to 3 times the impact of a normal flu season in terms of missed work, school, and vacations, according to a report released by Walgreens on October 16, 2013.
The report finds that US adults missed 230 million workdays and children missed more than 90 million school days during the 2012-2013 flu season due to flu-related illness. By comparison, adults missed 100 million workdays and children missed 32 million school days in the 2010-2011 flu season, the last to be covered by a similar Walgreens report.
In addition, the report estimates flu-related costs to employers in 2012-2013 at $30.4 billion, nearly triple the $10.5 billion cost in 2010-2011, and employees lost more than $8.5 billion in wages due to missed work. Flu activity peaked in December last season, and Americans missed 17 million holiday events and 11 million vacations due to flu in 2012-2013, compared with 4.7 million missed holiday events and 3.6 million missed vacations in 2010-2011.
The report was based on a survey conducted between August 27 and September 4, 2013, with 1200 nationally representative adults 18 years and older.
