          Objective To understand the epidemiological characteristics of newly reported human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) among the population aged ≥50 years in Pengzhou City of Sichuan Province during 2014–2018 and provide theoretical basis for comprehensive prevention and control of AIDS

          Methods The AIDS surveillance data of the population aged ≥50 years in Pengzhou City during 2014–2018 was collected from national AIDS prevention and treatment information system, and analyzed to know their distribution characteristics, transmission routes and sample sources.

          Results A total of 825 cases were reported during the study period. The proportion of HIV/AIDS cases aged ≥50 years old accounted for the total number of new reported cases every year, the lowest in 2014 (51.2%) and the highest in 2018 (73.1%). The most reported cases were in the age group of 50-<60-year-old, accounting for 40.5%;males were more than females; marital status was dominated by married couples, accounting for 61.8%; occupation was dominated by farmers, accounting for 85.0%; educational level was dominated by primary schools and below, accounting for 58.0%; the main route of infection was heterosexual transmission, accounting for 98.3%. The main source of case report was found in medical institutions, accounting for 81.0%, followed by CDC, accounting for 18.0%.

          Conclusion The number and proportion of reported HIV/AIDS cases aged ≥50 years old in Pengzhou are increasing year by year. Heterosexual contact is the main route of transmission and the detection of medical institution is the main way for case finding.
