Numerous studies have documented that a positive HIV diagnosis may trigger psychological distress and depression among FSW and other populations (Bhadra et al., 2020; Payán et al., 2019; Perrett & Biley, 2013; Zulliger et al., 2018) and that depression may be associated with suboptimal ART adherence and lower CD4 counts (Weinstein & Li, 2016). The gene discussed is CD4; the disease is depressive disorder.
