Objective: To determine the proportions and correlates of recent HIV infections among newly reported HIV/AIDS cases from 2005 through 2009 in Dehong prefecture, Yunnan province.
Methods: All available serum samples of newly reported HIV/AIDS cases during 2005 - 2009 period in Dehong prefecture, were tested using the BED HIV incidence capture enzyme immunoassay (BED-CEIA).
Results: A total of 9367 HIV/AIDS cases were newly reported in 2005 through 2009, of whom 7252 (77.4%) were tested with BED-CEIA. Among the tested, 954 (13.2%) were positive for BED-CEIA and were regarded as recent HIV infections. The proportion of recent HIV infection among newly reported HIV/AIDS cases was 11.21% in 2005, 11.87% in 2006, 17.55% in 2007, 13.22% in 2008, and 12.22% in 2009. Multiple logistic regression analysis indicated that the proportion of recent HIV infections among newly reported HIV/AIDS cases in 2009 was significantly higher among females, those aged 11 - 19 years, and internal residents outside of Dehong prefecture, but significantly lower among immigrants who were mostly from Myanmar, than local residents.
Conclusion: From 2005 to 2009, the proportion of recent HIV infections among newly reported HIV/AIDS cases in Dehong prefecture in Yunnan province was fluctuating slightly. Future research is needed to examine its long-term and secular trend. Such proportion was significantly different by different sociodemographic characteristics.
