56 Dean Street

56 Dean Street, based in Dean Street in London's Soho district, is a sexual health clinic. Part of the Chelsea and Westminster Hospital NHS Foundation Trust, it also has a second branch, Dean Street Express, located at 34 Dean Street, which offers a fast-turnaround testing service. As of 2017, the clinic was the largest HIV clinic in Europe. In addition to its specialism in HIV infection and other sexually transmitted diseases, it also offers general sexual health care services, including contraception. The clinic also runs TransPlus - the UK’s first integrated NHS gender dysphoria, sexual health and HIV service.

56 Dean Street is recognised internationally for its innovation, particularly in regard to its engagement with London's higher-risk communities as well as HIV epidemic management. HIV combination prevention is the multifactorial approach to addressing the HIV epidemic. It includes:

• engagement of high-risk communities in regular HIV testing
• condom awareness and use
• easy access to HIV-PEP (Post-Exposure Prophylaxis)
• quick-start HIV treatment; once diagnosed HIV positive, patients are prescribed HIV ART (Anti-Retroviral Therapy) within days after diagnosis, quickening their journey to an uninfectious status, reducing the number of infectious people within communities, and slowing the spread of infection in communities. This is called Treatment as Prevention
• PrEP, which can protect HIV-negative people from HIV infection. The clinic has made the provision of pre-exposure prophylaxis (PrEP) a priority.
• Behavioral advice, support, and psychosocial interventions (e.g. chemsex support, sexual wellbeing education and support)
• community awareness of all the above.

with the result being that new HIV infection rates in London have dropped dramatically since the introduction of these interventions.
