Influenza Update from CDC

Holly Harmon 
 
The CDC announced that influenza A (H3N2) viruses have been detected most frequently and have been detected in almost all states. There tend to be more severe seasons when H3N2 viruses predominate. About half of the H3N2s that have been analyzed since October are different from the H3N2 virus that is included in this season’s flu vaccine. They are different enough that the CDC is concerned protection from vaccination against these drifted H3N2 viruses may be reduced. CDC continues to recommend:
  •   Flu vaccination as the best way to protect against the flu. Vaccination may provide partial protection against the drifted viruses and should better protect against other non-drifted flu viruses that may circulate this season, including influenza B viruses
  • Antiviral medications as an important second line of defense against the flu. Treatment with antiviral drugs is especially important for people at high risk of serious flu complications or people who are very sick with flu. It's especially important to get antiviral medicines quickly – as they work best when started within two days of the beginning of flu symptoms.
  • Everyday actions like covering your cough, staying away from sick people, and washing your hands often. If you get the flu, stay home from work or school. If you are sick, do not go near other people so that you don't make them sick too.
