Cases of sexually transmitted infections in Scotland have trebled in the space of just ten years, prompting critics to call for a re-think in sexual health policy. The sharpest rise was in cases of genital chlamydia, with the number of diagnoses rocketing from 5,676 in 1999 to 18,277 in 2009. During the same period diagnoses of genital herpes increased from 933 to 2,627, while diagnoses of gonorrhoea nearly doubled. In addition, between 1999 and 2010 the number of HIV-infected people more than doubled from 156 to 360. John Deighan, parliamentary officer for the Roman Catholic Church in Scotland, said: ‘The more we find out about the prevalence of sexually transmitted infections the more worrying the picture that emerges. The distorted ideas of sexual liberation which have been popular for a few decades have taken a terrible toll on the lives of many people’.
