The flu epidemic has affected Americans from coast to coast, according to Forbes. Why the 2013 flu season is reportedly shaping up to be both earlier and more severe than others is unknown. The H1N1, or swine flu, virus is reportedly one of the most common circulating types of the ailment at the moment. The Centers for Disease Control report that during the week ending on December 29, there have been 2,961 positive influenza test results. Accu Weather also notes that 31.6 percent of patients tested for the flu actually had the ailment. The positive flu test figures reportedly indicate at 29.6 percent increase. The Center for Disease Control (CDC) separates the country into 10 geographical regions for flu outbreak review purposes. As of the last week of 2012 (the most recently available statistics) none of the 10 regions indicated elevated medical care requests for flu symptoms. Flu cases reportedly peak during the month of January.
