From: The origin, dissemination, and molecular networks of HIV-1 CRF65_cpx strain in Hainan Island, China
The inferred well-supported virus migration events of CRF65_cpx between the subgroups. Only results with Bayes factor (BF) ≥ 3 are presented. Arrows indicate the direction of the HIV-1 migration events. The colors were chosen to visually distinguish the different BF level values. A and D containing 136 sequences (Dataset-1) from different provinces, demonstrate viral migration events between provinces in China (3A) and the transmission pattern of HIV-1 CRF65_cpx (3D). B and C including 53 sequences only from Hainan (Dataset-2), present migration events among the age groups and cities in Hainan Province. Note. YP: Young people (aged 17 to 24 years old), MP: Middle-aged people (aged 25 to 40 years old), OP: Older people (OP, aged over 40 years old). MSM: Men who have sex with men. HETs: Heterosexuals. IDUs: Intravenous drug users. NA: Transmission route not available
