[Abstract]:Objective to investigate the epidemic characteristics of HIV / AIDS in Guizhou province from 2011 to 2015 and to provide evidence for making preventive and control measures. Methods using the data of the Integrated AIDS Prevention and treatment Information system, the new cases of AIDS from 2011 to 2015 were analyzed by descriptive epidemiology. Results the number of reported cases increased year by year, and 20 005 cases were reported. The ratio of male to female is 2.1: 1; the age is 20 to 49 years old, accounting for 65.2%, showing a downward trend and rising year by year; the Han nationality is the main ethnic group, accounting for 71.5%; the occupation distribution peasants are mainly, accounting for 44.9%, with the biggest increase; and all the 88 counties (districts) in the province have reported cases. Among the transmission routes, heterosexual and same-sex transmission showed an upward trend, while drug abuse transmission decreased year by year, the proportion of heterosexual transmission was 84.4, and the increase of cases in the older age group was much greater than that in the lower age group. Same-sex transmission mainly concentrated in the age group of 20-29 years old (56%); the sample came from other medical institutions, accounting for 42.2%; the number of screening tests increased year by year, and the positive rate rose first and then decreased. Conclusion the rate of increase of reported cases has decreased, and sexual transmission has become the main way of transmission. The number of reports of the elderly infected persons has increased year by year, the epidemic range is wide, the regional differences are large, the epidemic factors are complex, and the situation of prevention and control is severe.
