"The difference between general population UK, effectively zero prevalence, and the MSMs and African born, is to do with their practices."

This is evidentially untrue as young women and adolescent girls make up the highest demographic to suffer from ALL other STI's.

Chlamydia affects 10% of young women, while HPV affects a much higher number than that.

If it were down to practice, the levels of other STI's would be as low comparably as the levels of HIV.

In light of this information, it seems that Young Women and adolescent girls are lucky they have remained HIV free for so long.
