Infection rates aren't increasing in either younger or older people, health officials say. But the widespread use of antiretroviral drugs in patients in the U.S. has greatly extended the lives of AIDS patients and caused many more to live into later years. Today in the U.S., 28 percent of those living with HIV/AIDS are over the age of 50, and by 2015 that will increase to 50 percent, said Sen. Gordon H. Smith (R-Ore.)
Figures from 32 states show that the number of persons over 50 with HIV or AIDS went from 40,000 in 2000 to more than 67,000 in 2003, according to the Centers for Disease Control and Prevention. Older blacks are 10-15 times more likely than their white counterparts to be infected.
The agency remains worried that this growing segment of the population of HIV/AIDS older adults could provide a new reservoir for the spread of HIV.
"One of the challenges in people 50 and older is the mistaken belief that they're not at risk," Robert S. Jannsen, MD, director of CDC's division of HIV/AIDS prevention, told members of the Senate Committee on Aging.
Jannsen warned that older patients, raised before the AIDS emergence of the 1980s that made "safe sex" a buzzword among youth, are less likely to see the importance of using condoms. The fact that pregnancy is not a concern for most women over 50 may also make them less likely to think of condom use, he said.
Stereotypes and lack of awareness about the disease is another challenge in preventing the spread of the disease, added Smith.
