This year’s flu numbers are much like what was seen in 2007-2008, according to the CDC’s Influenza Division. Last year the influenza attack rates were very high because of the lack of population immunity to the new H1N1 virus. The flu hospitalization rate this year is worst among young children and seniors, in contrast with last season, when many people in their 20’s were hospitalized with H1N1.
This year, circulating flu strains are well matched to the 2010-11 seasonal vaccine. According to CDC surveys, the adult percentage of immunization is 42%, up from 33% during the 2008-09 season. More than 70% of physicians are immunized. Immunizations are still available, as the flu season is expected to last until May.
There have been 115 flu-related deaths this year, compared with 1994 fatalities at the same point during the 2009-2010 season.
