Objective To understand the epidemiological characteristics of HIV / AIDS patients 50 years old and above in Dongguan and provide a scientific basis for targeted prevention and control of AIDS in this population. Methods The epidemic data of HIV / AIDS cases aged ≥ 50 in Dongguan City from 2007 to 2012 were collected and analyzed by descriptive epidemiological method. Results A total of 195 HIV / AIDS cases aged ≥50 years were reported from 2007 to 2012, including 153 males and 42 females with a sex ratio of 3.64:1. 108 (50.38%) were 50-59 years old and 45 (23.08%), 42 (≥ 21.54%) ≥70 years old, 65.13% (127/195) of them had primary education and illiteracy, 26.7% (26.15% 51/195), followed by farmers (20.51%, 40/195). The main route of transmission is sexual transmission, accounting for 89.74% (175/195). The case fatality rate was 35.38% (69/195), higher than the overall epidemic mortality rate (14.56%, 299/2 054). The difference was statistically significant (P <0.01). Conclusion The impact of AIDS on people aged 50 years and older in Dongguan City has gradually emerged. Targeted measures should be taken to reduce the harm of AIDS to this population.
