{Abstract}: <B>UNASSIGNED: </B>This study aimed to determine the current epidemiological status of PLWHA aged ≥ 50 years in China from 2018 to 2021. It also aimed to recommend targeted interventions for the prevention and treatment of HIV/AIDS in elderly patients.<BR><B>UNASSIGNED: </B>Data on newly reported cases of PLWHA, aged ≥ 50 years in China from 2018 to 2021, were collected using the CRIMS. Trend tests and spatial analyses were also conducted.<BR><B>UNASSIGNED: </B>Between 2018 and 2021, 237,724 HIV/AIDS cases were reported among patients aged ≥ 50 years in China. The main transmission route was heterosexual transmission (91.24%). Commercial heterosexual transmission (CHC) was the primary mode of transmission among males, while non-marital non-CHC ([NMNCHC]; 60.59%) was the prevalent route in women. The proportion of patients with CHC decreased over time ( Z = 67.716, P < 0.01), while that of patients with NMNCHC increased ( Z = 153.05, P < 0.01). The sex ratio varied among the different modes of infection, and it peaked at 17.65 for CHC. The spatial analysis indicated spatial clustering, and the high-high clustering areas were mainly distributed in the southwestern and central-southern provinces.<BR><B>UNASSIGNED: </B>In China, PLWHA, aged ≥ 50 years, were predominantly infected through heterosexual transmission. The primary modes of infection were CHC and NMNCHC. There were variations in the sex ratio among different age groups, infected through various sexual behaviors. HIV/AIDS cases exhibited spatial clustering. Based on these results, the expansion of HIV testing, treatment, and integrated behavioral interventions in high-risk populations is recommended to enhance disease detection in key regions.
