Objective To analyze the epidemiological characteristics of newly-reported and late diagnosed HIV/AIDS cases from 2008 to 2014 in Heng County, aiming to understand current situation of HIV/AIDS in the county, to provide theoretical basis in prevention and control of AIDS in the future.

The occupation distribution showed that the farmers took up a large proportion, accounting for 84.59% of the total cases. From 2008 to 2014, the ratio of late diagnosed cases showed an increasing trend year by year, and all the differences had statistical meaning （P〈0.05）. Male cases were more than female cases in late diagnosed cases of newly-reported HIV/AIDS cases, patients in 〉150 years group occuped a higher propotion than in the other age groups.
