A large proportion of "heterosexual" men seropositive were probably infected by other males
About one-fifth of HIV infections among individuals of black African males, originally classified as a result of heterosexual exposure in the UK, were probably acquired after sex with other individuals of the same sex, the researchers reported.
The authors identified groups of HIV transmission in the UK and found that 29% of heterosexual transmissions happened, indeed, in groups of transfers involving only boys who had had relations with other men (MSM). The authors estimate that 6% of HIV infections in heterosexual males are poorly sorted and are actually acquired during sex with other men. However, the proportion of poorly sorted infections involves black African heterosexual men could be quite high, 21%. The study examined the genetic structure of the virus that infected 22.500 people in whom HIV was diagnosed in the UK, and between 1996 2008. Overall, 56% of heterosexual people could be placed in a transmission group that does not involve other heterosexuals. However, 31% were the groups involved, while straight and HSH, and representing straight lone 29% on transmission lines which involved only MSM. Heterosexual men of black African origin represented the ethnic group most likely to be linked exclusively to transmission MSM.
Comment: These results do not surprise probably all aware of the stigmatization of sexual relations between persons men in certain minority communities in the UK. Certain erroneous attributions about the sexuality of people in whom HIV has just been diagnosed, could also come from health workers, who also assume the sexuality of African patients.
