2 HIV: the story in 2014 People living with HIV can expect a near normal life expectancy and very good health outcomes if diagnosed in early stage of infection As a result of 30 years of prevention efforts, HIV in the UK remains relatively uncommon with an overall prevalence of 1.5 per 1,000 population (1.0 in women and 2.1 in men). An estimated 98,400 (93, ,300) people were living with HIV by the end of 2012 Late diagnoses and high undiagnosed infections remain the biggest challenge Around 21,900 (22% [18%-27%]) of persons with HIV remain unaware of their infection. Of the 6360 persons diagnosed for the first time in 2012, 47% were diagnosed late 2Presentation title - edit in Header and Footer

4 4HIV in the United Kingdom: 2013 A total of 77,610 people (770 children and 76,840 adults) received HIV care in in 4 adults living with diagnosed HIV are aged over 50 years. 97% linked to HIV care within 3 months of diagnosis with no differences by age, gender, ethnicity, sexual orientation, sex and area of residence. (195 persons were NOT) 95% of the 76,840 diagnosed adults are retained in care annually (3,850 were NOT) 89% receive antiretroviral therapy (8,500 were NOT), 92% of those with a CD4 <350 95% of persons on treatment achieve a VL<200copies/ml (3,400 did NOT) In England, key clinical indicators are monitored locally through the HIV Clinical Dashboard to maintain high standards of HIV care.

8 Black Africans

9 9HIV in the United Kingdom: 2013 Black Africans Black-Africans are the second largest group affected by HIV with 38 per 1,000 living with the infection (26 in men and 51 in women). 23% of the 31,800 (29,700-34,600) black-Africans living with HIV, remained unaware of their infection. Despite an overall decline over the past five years, an estimated 1,000 black- Africans diagnosed annually probably acquired HIV in the UK. High rates of late diagnoses Testing rates remain too low. Approximately 100,000 HIV tests (40,000 in STI clinics, 30,000 antenatal clinics and 30,000 in primary and secondary care settings) HIV in the UK, 2012

13 MSM Natsal III

14 MSM MSM remain the group most affected by HIV with 47 per 1,000 living with the infection (18% unaware= 8,000 men). An estimated 2,400 (1,600-4,100) MSM acquire HIV infection each year. New diagnoses continued to rise and reached an all time high of 3,250 in This reflects both an increase in HIV testing and on-going transmission. Compounded by high rates of STIs and ongoing risk of HCV Circumstantial evidence of an association between drug use and elevated STIs (other than HIV) HIV positive men have higher rates of risky behaviour and other STIs. 14

15 Gay and other MSM bear disproportionate burden of the HIV epidemic in virtually every country that reports reliable HIV data 15 Source: Beyrer, Baral, van Griensven, Goodreau, Chariyalertsak, Wirtz, Brookmeyer, The Lancet, 2012

18 HIV the story in 2014 New set of biomedical prevention tool available with focus on TasP & Prep TasP alone is unlikely to be sufficient to reduce HIV transmission in the UK since it is estimated that two-thirds of HIV positive people with detectable viral loads are unaware of their infection. Earlier treatment must be combined with a substantial increase in the frequency of HIV testing among groups most affected. 18Presentation title - edit in Header and Footer

19 HIV testing Natsal III

20 20HIV in the United Kingdom: 2013 Late diagnosis has declined over the past decade but remains high in 2012 (47% overall, 34% in MSM and 58% in heterosexuals) 64 of 326 (20%) local authorities across England had a prevalence of diagnosed HIV infection of ≥2 per 1,000 population (aged years), the threshold for expanded testing (BHIVA 2008 & NICE 2010 guidelines) In 2014, there is little evidence of expanded HIV testing taking place in high prevalence areas HIV testing

21 HIV testing in STI clinics Testing rates have improved in STI clinics with 900,000 tests in 2012 But remain too low in higher risk groups: 70,000 among MSM and 40,000 in black Africans 49% of MSM were diagnosed at their first HIV test at that STI clinic 21Presentation title - edit in Header and Footer

22 Prevention is better than cure

23 All people: Age, longer term condomless anal sex partner, number of short-term condomless anal sex partners People with HIV: CD4 count, viral load, ART drugs, adherence, resistance, risk of AIDS / death. Phillips et al HIV Synthesis transmission model of HIV in MSM Simulation model - each time the model program is run it creates a ‘dataset’ of the lifetime experiences of a 1 in 10 sample of adult MSM in UK Methods and fit to HIV natural history and effect of ART extensively documented in Phillips et al, PLOS One 2013

24 Counter – factual scenarios, Phillips PLOS One 2013 No condom use (a)ART at diagnosis from 2000 (b)Increased testing rates (c)Higher testing and ART at diagnosis (A) (d) NOTE (A)Cessation of all condoms in 2000 would have resulted in a 400% increase in incidence 24

25 Scaling HIV testing HIV testing is a gateway for more tailored approach, and access to, behavioral and biomedical interventions Key challenge will be optimising HIV testing programmes Increase HIV testing frequency by providing acceptable options Test whose at high risk, but currently not testing Use new testing options to leverage networks Use internet-based technologies Integrate HIV testing into routine care in range of health care settings 25

26 Whole system approach Evidence that particularly sexual risk taking behaviour can only be addressed by tackling syndemic factors including depression, substance use, violence, sexual stigma, homophobia and homelessness 26

28 Strategy for MSM Promote sexual health across the lifecourse Tackling homophobia and bullying Increase use of high-quality, coordinated educational, clinical, and other preventive services Increase knowledge, communication, and respectful attitudes regarding sexual health Promoting opportunities to discuss role of pleasure, satisfaction and ability to have the best sex with the least harm Increase healthy, responsible, and respectful sexual behaviors and relationships Decrease adverse health outcomes, including HIV/STDs, viral hepatitis, and sexual violence 28 Source: Douglas JM Jr, Fenton KA. Public Health Rep Mar-Apr;128 Suppl 1:1-4

29 Enhancing MSM HIV Prevention Comprehensive Clinical Care Work with providers to address stigma, discrimination, homophobia and provide comprehensive care culturally competent health care that addresses health needs As major sources of information and vital services, health providers play a key role, and must be trained to provide supportive, non-judgmental care Well-trained clinicians who understand realities and contexts Use provider engagement can to enable healthier lifestyles 29Adapted from Mayer et al 2012

30 Conclusions HIV is here to stay but no one should die of AIDS We have a unique opportunity to refocus prevention and testing efforts Re-investing a small amount of the savings from switch to generics into prevention and testing strategies will within a few years prevent thousands of HIV infections and save lives 30Presentation title - edit in Header and Footer
