The number of persons aged 50 years and
older living with HIV/AIDS has been
increasing in recent years. This increase is
partly due to highly active antiretroviral
therapy (HAART), which has made it possible
for many HIV-infected persons to live
longer, and partly due to newly diagnosed
infections in persons over the age of 50. As
the US population continues to age, it is
important to be aware of specific challenges
faced by older Americans and to ensure that
they get information and services to help
protect them from infection.
In 2005, persons aged 50 and older accounted for
- 15% of new HIV/AIDS diagnoses1*
- 24% of persons living with HIV/AIDS (increased from 17% in 2001)1*
- 19% of all AIDS diagnoses1
- 29% of persons living with AIDS1
- 35% of all deaths of persons with AIDS1.
The rates of HIV/AIDS among persons 50 and older were 12 times as high among blacks (51.7/100,000)
and 5 times as high among Hispanics (21.4/100,000)
compared with whites (4.2/100,000).2

Persons over the age of 50 may have many of the
same risk factors for HIV infection that younger
- Many older persons are sexually active but may
not be practicing safer sex to reduce their risk
for HIV infection.3 Older women may be
especially at risk because age-related vaginal
thinning and dryness can cause tears in the
- Some older persons inject drugs or smoke crack
cocaine, which can put them at risk for HIV
infection. HIV transmission through injection
drug use accounts for more than 16% of AIDS
cases among persons aged 50 and older. 5
- Some older persons, compared with those who
are younger, may be less knowledgeable about
HIV/AIDS and therefore less likely to protect
themselves. Many do not perceive themselves as
at risk for HIV, do not use condoms, and do not
get tested for HIV.6,7
- Older persons of minority races/ethnicities may
face discrimination and stigma that can lead to
later testing, diagnosis, and reluctance to seek
- Health care professionals may underestimate their older patients' risk for HIV/AIDS and thus may miss opportunities to deliver prevention messages, offer HIV testing, or make an early diagnosis that could help
their patients get early care.3
- Physicians may miss a diagnosis of AIDS because some symptoms can mimic those of normal aging, for example, fatigue, weight loss, and mental confusion. Early diagnosis, which typically leads to the prescription of HAART and to other medical and social services, can
improve a person's chances of living a longer and healthier life.
- The stigma of HIV/AIDS may be more severe among older persons, leading them to hide their diagnosis from family and friends. Failure to disclose HIV infection may limit or preclude potential emotional and practical support.
What CDC Is Doing
CDC recommends routine HIV screening for adults and adolescents, including pregnant women, in health care settings in the United States and recommends reducing barriers to HIV testing.9 The recommendations specify routine testing for persons up to age 64. (Persons aged 64 and over should be counseled to receive HIV testing if they have risk factors for HIV infection.) Routine testing is intended not only to identify persons who are unaware that they are HIV infected but also to remove the stigma of being tested. Making testing routine for older persons can help open a discussion about risk behavior between a physician and an older person.
Prevention strategies should be developed for older persons who are potentially at risk for HIV infection: education to increase awareness and knowledge, skills training to help them negotiate risk-reduction behaviors, and messages that are age-appropriate and culturally sensitive. Intervention strategies to help older women negotiate safer sexual behavior are especially important.
A recent review of HIV/AIDS behavioral interventions for persons 50 and older recommended simultaneous multilevel approaches, including building on our current understanding of behavior change and HIV prevention successes with younger populations while considering important intervention principles gathered from work with older populations in other health areas.
