Influenza Update Week Ending 2-03-2018

Week ending 2-3-18 The CDC reported that influenza activity (diagnosed flu and Influenza-Like-Illness) increased once again.  Levels have met or exceeded flu and ILI markers from flu seasons over the last decade, including the 2009 Pandemic of H1N1.  Although Week #5 is the 11th week of substantial flu activity, and flu activity would normally have peaked by now, that is not the case and the CDC suggests that flu activity may go on for as long as 20 weeks.

Deaths associated with flu have reached system-specific epidemic thresholds. The dominating flu subtype remained A H3N2, which is typically a...

Influenza Update Week Ending 12-23-2017

Earlier in this flu season, the CDC posted an expectation that this flu season (2017-18) would likely start early and be more severe (as it was last year) than previous few flu seasons. This prediction was made based on the severe flu season that Australia was experiencing and since Influenza A H3N2 was the predominant strain. Flu seasons in the Southern Hemisphere are often good predictors of North American flu seasons since there winter occurs during our summer. This...
