For World AIDS Day 2018 and 2019 we partnered with UNAIDS to present some key findings from the European and Latin American MSM Internet Surveys on the UNAIDS website for key populations. Findings are shown as interactive maps that include various sexual health indicatiors for gay men, bisexual men and other MSM.

For each country we include percentages on:

  1. Crude Recruitment Rate: Number of men reached by EMIS / LAMIS, per 10,000 men aged 15-65
  2. HIV diagnosis: ever diagnosed with HIV (%)
  3. Recent HIV diagnosis: HIV diagnosis in the past 12 months (%), excluding men diagnosed with HIV more than 12 months ago NEW
  4. HIV testing: Tested for HIV in the last 12 months (%), excluding those diagnosed longer ago
  5. Community-based HIV testing: Using community HIV- testing at last HIV test (%, denominator includes untested  men) NEW
  6. Comprehensive STI screen: HIV test, STI blood test, rectal swab, urethral (trans men if applicable: vaginal) swab or urine in the last 12 months (%), excluding men diagnosed with HIV more than 12 months ago NEW
  7. Disclosure in health care: Disclosure of same-sex contacts towards health care provider during STI-testing in the last 12 months (%)
  8. Not open about sexual orientation (non-outness): "Out" to few or none of friends, family and at work (%) NEW
  9. Targeted information:  Saw or heard information about HIV/STIs for MSM, last 12 months (%)
  10. Received free condoms: Received free condom from NGOs, clinics, bars, or saunas, last 12 months (%)
  11. Condomless anal sex: Condomless anal sex with non-steady male partners of unknown HIV status, last 12 months (%)
  12. PrEP use:  Currently taking HIV pre-exposure prophylaxis daily or on demand (%), excluding HIV-diagnosed men
  13. Lack of PrEP knowledge: Not knowing that PrEP is a pill taken before as well as after sex to prevent HIV infection (%)  NEW
  14. Lack of PEP knowledge: Not knowing that PEP stops HIV infection after exposure (%) NEW
  15. Lack of U=U knowledge: Not knowing U=U (that a person with undetectable viral load cannot pass on HIV, %) NEW

Available in 33 languages, the European MSM Internet Survey (EMIS-2017) recruited 137,358 qualifying participants from 46 countries across Europe and Lebanon, Israel, Canada and the Philippines. The Latin American MSM Internet Survey (LAMIS) recruited 64,655 participants from 18 countries. EMIS-2017 was undertaken by researchers from Sigma Research at the London School for Hygiene and Tropical Medicine and the Robert Koch Institute as part of ESTICOM. LAMIS, using the same questionnaire and finishing data collection on 12 May 2018, was the first online multinational survey on psycho-socio-sexual health with intersectoral participation in Latin America. It was implemented by researchers from the Red Iberoamericana de Estudios en Hombres que tienen Sexo con Hombres y Personas Trans*, a coalition of researchers from Latin America, Portugal, Spain and the Netherlands, with support from the EMIS team. Both projects required a great deal of international cooperation and relied on the support of national stakeholders to aid local recruitment. Through this cooperation comparable data are now available for the first time for more than 60 countries across 4 continents.
