Sleep and HIV Disease

Although not the fatal illness it once was, HIV/AIDS remains a life-threatening illness. The worldwide prevalence of HIV/AIDS at the end of 2010 was estimated to be 34 million, which includes 3.4 million children who are less than 15 years of age. The incidence of HIV infection decreased from 3.1 million in 2001 to 2.7 million in 2010. The annual number of deaths worldwide is steadily declining since peaking in 2005 at 2.2 million.
