Cdc mandating h1n1 shot
In most influenza seasons, the majority of influenza-associated hospitalizations and deaths are among adults aged 65 years and older [2, 3].However, during the 2009 pandemic, p H1N1 caused more illness in children and young adults than in older adults .Early observations from the 2013-14 influenza season indicate that some persons infected with p H1N1 virus have had severe illness.While most of these people with severe illness have had risk factors for influenza-associated complications, including pregnancy and morbid obesity, several have not.
Clinical trials and observational data show that early antiviral treatment may (1) shorten the duration of fever and illness symptoms, (2) reduce the risk of complications from influenza (e.g., otitis media in young children, pneumonia, respiratory failure and death), and (3) shorten the duration of hospitalization.
The p H1N1 virus that emerged in 2009 caused more illness in children and young adults, compared to older adults, although severe illness was seen in all age groups.
While it is not possible to predict which influenza viruses will predominate during the entire 2013-14 influenza season, p H1N1 has been the predominant circulating virus so far.
In the 2012-13 influenza season, CDC estimates that there were approximately 380,000 influenza-associated hospitalizations .
Although influenza activity nationally is currently at low levels, some areas of the United States are already experiencing high activity, and influenza activity is expected to increase during the next few weeks.
