My favorite site for flu data, distribution and spread in the U.S. is the CDC Flu Weekly site. Good data looking at trends state-by-state as well as flu types, age groups, hospitalizations and deaths.
The flu season continues to be a bad one with Influenza A (H3N2) being the predominant strain. This strain first emerged during the 1968 Flu Pandemic and is known for causing serious illness.
This is a good time for emphasizing hand hygiene, cough protocols and stay at home if you are sick guidelines at your workplace.
