Public Health England exists to protect and improve the nation’s health and wellbeing and reduce health inequalities. This is done through world-leading science, knowledge and intelligence, advocacy, partnerships and the delivery of specialist public health services. Key information from the government report states that there has been a decline in new HIV diagnosis among gay, bisexual and other men who have sex with men has been observed for the first time since the epidemic was detected over 30 years ago and this decline was focused in 5 London clinics, which delivered high levels of HIV testing, including frequent testing of men at high risk of HIV and so we can gather from this information that the decline in new diagnosis in gay and bisexual men is due to reduced transmission of HIV, meaning that there has been an increased in the care/ treatment/ awareness that is being given to those dealing with the virus so to limit the transmission of it onto others. There has also been a continued decline in new HIV diagnosis among black African heterosexual men and women and this decline is due to changing patterns of migration, with fewer people from high HIV prevalence countries coming to the UK. However, among white heterosexual women and men, new HIV diagnosis have remained stable but low at around 750 per year over the past decade.
