In the United States, influenza viruses can be counted on to cause outbreaks sometime between fall and spring each year. However, the timing and severity of these epidemics and the distribution of circulating viruses are highly variable and difficult to predict (see figure Percentages of Patient Visits for Influenza-like Illness and Number of Reported Deaths among Children for the 2012?2013 Season to Date and for Selected Previous Seasons.). For example, according to the Centers for Disease Control and Prevention (CDC), the estimated number of influenza-associated deaths varies from 3000 to 48,000 during a seasonal U.S. outbreak.
