Estimation and projection of the HIV epidemic trend among the migrant population in China / 生物医学与环境科学（英文）

ABSTRACT

<p><b>OBJECTIVE</b>The migrant population is a vulnerable group for HIV infection in China. Understanding potential epidemic trends among migrants is critical for developing HIV preventative measures in this population.</p><p><b>METHODS</b>The Estimation and Projection Package (EPP) model was used to process prefecture and county-level surveillance data to generate HIV prevalence and epidemic trends for migrant populations in China.</p><p><b>RESULTS</b>The prevalence of HIV among migrants in 2009 was estimated at 0.075% (95% CI 0.042%, 0.108%) in China. The HIV epidemic among migrants is likely to increase over the next 5 years, with the prevalence expected to reach 0.110% (95% CI 0.070%, 0.150%) by 2015.</p><p><b>CONCLUSION</b>Although the 2009 estimates for the HIV/AIDS epidemic in China indicate a slower rate of increase compared with the national HIV/AIDS epidemic, it is estimated to persistently increase among migrants over the next 5 years. Migrants will have a strong impact on the overall future of the HIV epidemic trend in China and evidence-based prevention and monitoring efforts should be expanded for this vulnerable population.</p>
