I have not seen a specific statement from the CDC that 
suggests that the 1999-2000 flu season was not unusual, but 
I have found this statement, "This was the third consecutive 
year that influenza A/Sydney/05/97-like (H3N2) viruses were 
the most prevalent viruses isolated in the United States. 
Influenza activity in the United States was similar to the 
previous two seasons, although mortality measurements 
attributed to pneumonia and influenza (P&I) were unusually 
high."  This statement comes from: 
http://www.cdc.gov/epo/mmwr/preview/mmwrhtml/mm4917a5.htm
.  Because the CDC has altered its recommendations for 
vaccinations this year, at least partly in response to "P&I" 
having been unusually high previously, I suggest that the 
CDC recognizes that last flu season was a little unusual.
