Abstract
What is already known about this topic? The annual rates of newly diagnosed cases of human immunodeficiency virus (HIV) are increasing in China, yet the annual number of newly diagnosed cases of HIV infected through injection drug use (IDU) is decreasing. What is added by this report? Newly diagnosed cases of HIV infected through IDU in China from 2012 to 2019 show decreases year over year, but the risk of new infections through injecting drugs still exists. What are the implications for public health practice? This study highlighted that new HIV infections through IDU continue to be at a low level. However, individuals that are newly diagnosed as HIV-positive through IDU need to have their baseline CD4 T+ lymphocytes (CD4) cell counts monitored and have their sources of infections traced.
