Abstract:
Objective:To analyze the epidemic characteristics and trends of newly reported HIV-infected people among Chinese and Burmese in Dehong Dai and Jingpo Autonomous Prefecture (Dehong Prefecture) of Yunnan Province, China, from 2000 to 2023, and provide evidence for formμlating AIDS prevention and control measures for the Burmese living in Dehong.Methods:The data were obtained from the Chinese Disease Control and Prevention Information System. The distribution of HIV-infected people with different population characteristics was analyzed, and the Joinpoint regression model was used to analyze the temporal trend of crude detection rate in different genders, ethnicities, and ages.Results:From 2000 to 2023, 24 989 newly HIV infections were reported in Dehong Prefecture, of which 14 594 (58.4%) were Chinese and 10 395 (41.6%) were Burmese. Compared with Chinese, Burmese women (32.9%, 3 416/10 395), those aged 20-29 (40.9%, 4 248/10 395), and Jingpo people (26.7%, 2 773/10 395) accounted for a higher proportion. The new diagnosis rate of Chinese nationals increased from 1.0/10 000 in 2000 to 15.4/10 000 in 2004, and then showed a downward trend, falling to 1.2/10 000 in 2023. Among them, compared with other age groups, Dai and other ethnic groups and women, the new diagnosis rate among 20-49 age group, Jingpo and men were relatively higher, at 1.7/10 000, 2.3/10 000 and 1.3/10 000 respectively. Regarding the method of detection, the Chinese HIV-infected people were mainly detected by key population testing (35.7%), while the Burmese HIV-infected people by key population testing (28.9%) and physical examination for entry-exit personnel (25.3%). The transmission routes of both nationalities were mainly heterosexual transmission, but compared with Chinese HIV-infected persons, the proportion of Burmese infected persons through non-marital non-commercial transmission was relatively higher (66.4% vs. 60.6%). The proportion of Chinese nationals with a first CD4 +T lymphocyte (CD4) counts of <200 cells/μl (28.9%) was higher than that of Burmese nationals (19.8%). Conclusions:The rising trend of HIV infection among Chinese and Burmese people in Dehong Prefecture from 2000 to 2023 slowed down. The new diagnosis rate was higher in the 20-49 age group, Jingpo and men. Compared with Burmese HIV-infected people, the proportion of Chinese HIV-infected people with first CD4 counts <200 cells/μl was relatively higher. Comprehensive interventions should be further carried out for Myanmar nationals, and efforts should be made to expand testing for Chinese nationals.
