BACKGROUND Many people from Burma have migrated to Dehong prefecture and married local residents during the past decades; however, little is known about HIV risk-taking behaviours and HIV prevalence among these mixed couples. We investigated factors correlated with HIV discordance and concordance within Chinese?Burmese mixed couples in Dehong prefecture, Yunnan province, China. METHODS A cross-sectional study with face-to-face questionnaire interviews and HIV blood testing was conducted. RESULTS Of 5742 couples, 1.6% couples were HIV-infected concordant, 2.2% were HIV serodiscordant with an HIV-infected male spouse and 0.9% were HIV serodiscordant with an HIV-infected female spouse. HIV discordance with an HIV-infected male spouse was significantly associated with characteristics of the male spouse, including being aged =30 years, non-Han ethnic minority, a marital relationship of <3 years, commercial sex and injection drug use by the male spouse. HIV discordance with an HIV-infected female spouse was significantly associated with an education level of primary school (v. illiterate); a marital status of being in their second marriage, widowed or divorced; a history of sexually transmissible infection diagnosis of the female spouse; noncommercial extramarital sex by the female spouse or by both spouses; and injection drug use by the male spouse. A marital relationship of =3 years was the only significant independent correlate of HIV-infected seroconcordance. CONCLUSIONS The study findings underscore the importance of premarital HIV counselling and testing for this population, and the need for targeted interventions among HIV serodiscordant mixed couples to reduce secondary transmission as early as possible when the relationship begins.

Objective We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations. Methods 2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS’ National AIDS Spending Assessment methodology. Results Nearly 93% of total expenditures for HIV/AIDS was contributed by public sources. Of total expenditures, 52.7% was allocated to treatment and care, 24.5% to program management and administration and 19.8% to prevention. Spending on treatment and care was primarily allocated to the treatment of opportunistic infections. Most (40.4%) prevention spending was concentrated on most-at-risk populations, injection drug users (IDUs), sex workers, and men who have sex with men (MSM), with 5.5% allocated to voluntary counseling and testing. Prevention funding allocated for MSM, partners of people living with HIV and prisoners and other confined populations was low compared to the disproportionate burden of HIV/AIDS in these populations. Overall, people living with HIV accounted for 57.57% of total expenditures, while most-at-risk populations accounted for only 7.99%. Conclusions Our study demonstrated the applicability of NASA for tracking and assessing HIV expenditure in the context of China, it proved to be a useful tool in understanding national HIV/AIDS response from financial aspect, and to assess the extent to which HIV expenditure matches epidemic patterns. Limited funding for primary prevention and prevention for MSM, prisoners and partners of people living with HIV, signal that resource allocation to these key areas must be strengthened. Comprehensive analyses of regional and national funding strategies are needed to inform more equitable, effective and cost-effective HIV/AIDS resource allocation.

We retrospectively examined the timing of antiretroviral therapy (ART) initiation and CD4(+) T-cell recovery over 36 months among recent human immunodeficiency virus (HIV) infections using BED (HIV-1 subtypes B, E and D) immunoglobulin G capture enzyme immunoassay (BED-CEIA). Regardless of baseline CD4(+) counts, individuals (n = 393) who initiated ART >2 months after diagnosis had significantly decreased probability and rate of achieving CD4(+) counts ≥900 cells/μL or ≥600 cells/μL than those individuals (n = 135) who started ART earlier (≤2 months). But the mean CD4(+) counts in two groups converged after 30 months of treatment. Early ART initiation leads to accelerated CD4(+) recovery, but does not offer a long-term advantage in CD4(+) counts.
