Musket, your statement that if the figures are given as a range they are preliminary, is false.
YOU MADE IT UP.
The 2012 figures are the final, definitive figures. They will now be working on 2013.

Anyway, they are not given as a range.

"New HIV diagnoses, recent infection and
incidence
In 2012, 6,360 people (4,560 men and 1,800 women) were newly diagnosed with HIV in the
UK, a slight increase on 6,220 diagnoses in 2011. Like the previous year, this is an estimated
new HIV diagnosis rate of 1.0 per 10,000 population
(1.5 per 10,000 men and 0.57 per 10,000
women) (Appendices 2, 3 and 4). While overall trends show a decline in new HIV diagnoses
since 2005 (7,930) (Figure 2), this is largely due to a decrease in the number of diagnoses
reported among heterosexuals born in countries with high HIV prevalence. The number of new
diagnoses among persons born in Africa declined from 42% in 2008 to 29% in 2012.

Overall, 14% (390/2,880) had a recent infection (in the previous six months) at diagnosis in
England, Wales and Northern Ireland (Appendix 5)."

"In 2012, new diagnoses among MSM increased by 10% from 2,960 in 2011 and in London, by
14% from 1,400 in 2011 to 1,600 in 2012 (Figure 4). The proportion of new diagnoses that were
probably recently acquired infections among MSM in England, Wales and Northern Ireland in
2012 was 19% (Appendix 5); in London this was 22%."

"Heterosexual men and women
People who acquired their infection through heterosexual contact were the second largest
group of people newly diagnosed with HIV in 2012. After adjusting for missing risk information,
they accounted for 2,880 (45%) of new HIV diagnoses. Over the last decade, the number of
new diagnoses among heterosexuals declined in England, especially in London. In 2012,
numbers were highest in London (1,020; 35%) followed by the PHE regions Midlands and the
East of England (590) and the North (400) and South of England (370).
In Scotland, Wales
and Northern Ireland, the numbers of new diagnoses acquired heterosexually were lower, with
110, 50 and 40, respectively (Figure 5).

In 2012, a higher number of heterosexual women (1,530) than men (1,050) were newly
diagnosed with HIV. The median age of diagnosis was 39 years overall; 42 years among men
and 37 years among women.

The proportion of new diagnoses that were recently acquired HIV infections was 6% (30/440)
among heterosexual men and 8% (50/640) among women. "

SO, NOT GIVEN AS A RANGE, AND YOUR STATEMENT WAS UNTRUE ANYWAY.

Do you have one single bit of evidence,(not made up!) any evidence you can show us at all, that heterosexual transmission is not falling?

If not, you are proved wrong.
Again.
