Issues: How do we track our failures and successes? • Quality of data – how to define migrants and collect data without potential for discrimination and stigma? • Comparable data – agreeing on standard definitions • Lack of registers of death data – NO ONE SHOULD DIE OF AIDS IN 2014 • Critical monitors – testing uptake, diagnoses, link to care, retention in care, ARV uptake, viral suppression • Need for patient level data – ensure most at risk groups are captured (eg MSM, SW) • Data should drive health service response AND public health response including prevention efforts.

Sexual transmission of HIV (2013) ECDC project headed by UK/ spanish team Objectives of the project* • What is the evidence for ongoing sexual transmission of HIV among migrants after arrival to the EU? • What are the implications for HIV surveillance, policies and prevention programmes? RESULTS • There is evidence to show that some on-going post-migration HIV acquisition is occurring in EU countries • However, it is difficult to quantify the degree to which this is occurring RECOMMENDATIONS • Member States should consider applying an objective method for assigning PCOI • Evidence-based programmes and policies to reduce post-migration HIV acquisition and transmission are needed *Project led by Fiona Burns, Ibi Fakoya, Julia Del Amo and Valerie Delpech

Summary • Steep decline of reported HIV cases in Europe among heterosexuals from sub-Saharan African countries, however, migrants account for a significant proportion of reported HIV cases per annum (36% in 2011) • Migrants are being diagnosed later for HIV than other key populations and more likely to die of AIDS • There is evidence that migrants are being infected after arrival to the EU • Good surveillance at the patient level which are confidential and adhere to data protection rules (ie preferably donot collect names) are essential in tracking our progress in the HIV response and ensuring resources target the most affected population • Death registers are a priority in the 21st century. Legal barriers and perceived and real stigma must be addressed.
