Influenza, more commonly referred to as "flu," is a highly contagious viral infection of the nose, throat, and lungs. Influenza occurs most often in the late fall, winter, and early spring. It is a serious infection which affects more than 60 million individuals in the US every year.
Influenza impacts people of all ages. Common symptoms include a high fever (101ºF-102ºF) that begins suddenly, muscle/body aches, chills, tiredness, and sudden onset. Influenza frequently causes people to miss school and work but in some cases there are severe complications such as pneumonia. In the United States annually, more than 200,000 individuals are hospitalized and between 3,000-49,000 die from influenza-related complications.
The best way to protect against influenza is to receive an influenza vaccination every year. CDC recommends that everyone six months of age and older receive an annual vaccination. The best time to get vaccinated is in the early fall, as soon as the vaccine is available. However, vaccination in December or even later is still beneficial because the virus that causes influenza circulates past the new year. The number of influenza cases usually peaks around February, but this peak can come earlier or later (ranging from December to May).
NFID is committed to increasing public awareness of the importance of annual influenza vaccination.
