Results A total of 540 cases of HIV / AIDS were reported in Zhaotong City from 2005 to 2014, with a mean age of 62.1 ± 8.9 years, 67.8% (366/540) of males and 32.2% of females (174 / 540). The levels of literacy and primary education were 42.2% (228/540) and 40.4% (218/540), respectively; the number of job-based farmers was 76.6% (414/540); the number of married persons was higher, Accounting for 65.0% (351/540). The transmission route was mainly heterosexual transmission, accounting for 93.3% (504/540). The elderly were mainly distributed in counties (districts) with heavy epidemic and economically advanced population. The proportion of HIV / AIDS ≥50 years old in the newly reported year increased gradually from 1.7% in 2005 to 36.0% in 2014 (χ2 trend = 197.9, P <0.01); heterosexual contact transmission Accounting for the proportion of the report year from 10.0% in 2005 to 37.0% in 2014, the difference was statistically significant (χ2 trend = 119.5, P <0.01).
