Of the 27, several had attended GU services in the preceding three months with features common to their presentations including: high STI rates, selling of sex, adult film work, sex parties, chemsex, use of PEP and HIV seroconversion in the previous 12 months. Methods The outbreak control team included a health adviser, GUM consultant, PHE health protection specialist and local authority public health. An implementation strategy was developed with immediate control measures and longer term service planning and development. A literature search established an STI outbreak linked to a single household to be a new precedent. Results Immediate control measures: Outreach visit to and confidential inquiries of the residenceTargeted messages on MSM appsAssuring consistent use of Treatment as PreventionMDT education on current MSM trends with enhanced training for health advisersAddition of a drugs worker clinic Service development: GU clinic needle exchangeImproved electronic patient record data outputComprehensive analysis of local MSM populationImproved engagement with commissioning and drug/alcohol services Discussion/conclusion As the trend of chemsex and sex parties continues, it is likely there will be an increase in STIs linked to households. Better geospatial analysis of STI trends and collaborative working with public health is essential for rapid identification and control of outbreaks. ER -
