Objective The study described in this paper was designed to have a better understanding of the epidemic characteristics of the over 50 years old HIV/AIDS people in Liuzhou city so as to provide scientific evidence for the government to establish the prevention and care measures. Method The data including the reports on over 50 years old HIV/AIDS cases in Liuzhou from 1999 to 2010, surveillance, and special surveys were collected and analyzed. Results The cumulative number of HIV/AIDS positive cases reported was 1 788, incuding 977 AIDS patients and 608 deaths. Of all,1 367 cases were male,421 cases were female, the ratio of gender was 3.25：l,the average age was （61.61±8.01）, 50.78% was peasants, and 73.43% was lower than junior high school level. The infection route was 75.84% heterosexual transmission. The trend through heterosexual transmission went up from 1999 to 2010, and the HIV prevalence had climbed to 96.94%. With the in crease in ART treatment the survival time for the 50 years old HIV/AIDS people was prolonged, but only 3.34% was longer than 3 years, still shorter than the average of the general population（12.29%）. This phenomenon might due to the fact that they were not promptly diagnosed when they were infected, thus caused the delay of treatment. Conclusions HIV/AIDS spread rapidly among the over 50 years old people, and the prevention and control of AIDS was very difficult. Therefore effective prevention and control measure should be implemented as soon as possible.
