[Analysis on the ' late diagnosis' (LD) phenomena among newly identified HIV/AIDS cases in China, 2010-2014].

OBJECTIVE: To analyze the late diagnoses (LD) phenomena among newly identified HIV/AIDS cases in China from 2010 to 2014. METHODS: Newly identified HIV/AIDS cases from 2010 to 2014 were selected from the National HIV/AIDS comprehensive information system. Rates related to LD were stratified according to the demographic indicators. RESULTS: From 2010 to 2014 numbers of newly identified HIV/AIDS cases were reported as 64 338 74 517 82 434 90 119 and 103 501 in China. Among them proportions of LD were 41.8% 42.1% 38.1% 36.8% and 35.5% respectively. LD proportions appeared high in medical settings with the minimum proportion as 45% (chi(2)=5 174P<0.000 1). Proportion of LD among patients who were heterosexually transmitted appeared over 40% which was significantly higher than that seen among men who have sex with men or injecting drug users (chi(2)=3 066P<0.000 1). Proportion of LD showed more than 39% in those newly identified cases and was seen higher in permanent residents than in floating population (less than 30%) (chi(2)=5 265P<0.000 1). CONCLUSION: With the expansion testing coverage on HIV newly identified HIV/AIDS increased year by year. Among the newly identified cases late diagnosis was high especially in medical institutions. More effective strategies and measures are needed to promote the early detection of HIV in high risk population.
