[Conducting analysis on HIV tracing and molecular network for promoting precise detection,prevention and control of AIDS].

The current sexual transmission of newly infected HIV cases is complicated in China. It is crucial for interrupting HIV transmission by HIV tracing and molecular network analysis,conducting early detection and precise prevention among HIV-positive individuals. The articles in this issue focused on the global situation of HIV tracing, and molecular network analysis in promoting accurate detection and prevention of AIDS started from analyzing the reported epidemiological characteristics of HIV/AIDS in Ningbo city from 2017 to 2020. Relations of HIV transmission between HIV positive individuals and sex partners by tracing investigation were also, analyzed. Data on HIV transmission mode by combining social and molecular networks were gathered to provide evidence for applied research on precise detection, prevention, and control of AIDS.
