Introduction (.5 pages)
Seasonal influenza commonly referred to as the “flu” is an acute viral infection caused by the influenza virus that can have possibly devastating effects on a community (“Influenza (Seasonal),” 2014). Seasonal influenza viruses cause annual epidemics that peak during the winter but can begin as early as late fall and last through early spring (“Prevention and Control of Influenza,” 2008). Influenza infections in the US affect a large amount of the US population. On average in the United States 200,000 people are hospitalized due to influenza infections (“Vaccine-Preventable Adult Diseases,” 2016). In addition, the annual death toll in the United States alone related to influenza and its complications is about 20,000 (Fallon, 2013). Though influenza can affect people at any age, the rates of serious illness and death are among the highest in persons aged sixty-five or older (“Prevention and Control of Influenza,” 2008). The disproportionate effect of the influenza infection on older adults calls for public health interventions.
