HIV prevalence aged fifty and older

The CDC released its HIV surveillance report 2005-2008 in June and Dr. Stephen Karpiak of ACRIA just sent me the data on HIV prevalence in the over fifty population.  The number of people over age fifty is increasing exponentially, and one of the greatest population increases is for people between the ages 50-65.  These figures include increases in the rates of new reported cases of HIV, as well as people living with the virus over age 50.  Looking at these figures I conclude that midlife and older people living with HIV are going to represent a growing percentage of those living with HIV in the US and the specific issues faced by this age group are a growing health concern.

In 2007 the total estimated number of people living with HIV/AIDS climbed over the million mark, and the percentage of people estimated to be living with HIV/AIDS over age 50 was 31%.  This percentage rose in 2007 from less than 26% estimated in 2005.  Given the rate of increase (2.2%) we can estimate the current (2010) number of people living with HIV over fifty to be closer to 40%. 

The CDC also estimates that in 2008 16% of new diagnoses of HIV occurred in people over fifty.  This is an increase from the 2006 CDC estimate of 10%.
