Attempts to control the spread of sexually transmitted infections (STIs) have proved very difficult over the centuries and, in 2004, HIV/AIDS remained in the top 10 causes of death across the world (WHO, 2010a). Data from 2004 onwards are expected from the World Health Organization in 2011 but the evidence suggests that STIs remain on the increase (Online Statistics, 2010). Sexual activity is the perfect medium to spread infection with close contact and the exchange of body fluids and so it is unsurprising that these infections have survived for so long. Newly identified infections such as HIV/AIDS and the Human Papilloma Virus (HPV) have also been recorded. Chlamydia, one of the most common STIs today, was identified in 1957 and the incidence has continued to increase (HPA, 2010).
