Number of new HIV diagnoses

Belgium

Czechia

Foreigners with short-term stays in the Czech Republic are not included in cases notified

Estonia

Surveillance system substantially modified in 2008. Previously, the probable mode of HIV transmission was not reported by Estonia (from 2003 to 2007 Estonia supplied partial information on PWID only)

France

Case-based data are not exhaustive because of reporting delays (cases reported several months or years after the diagnosis) and underreporting (cases that are diagnosed but never reported). The most recent estimates of underreporting in France are 41% in 2007-2009 for AIDS and 30% in 2015 for HIV.  To assess the real numbers and trends of HIV and AIDS diagnoses in France, it is essential to use adjusted data, which take into account reporting delays, underreporting and missing data (incomplete reports). Adjusting for these factors, the estimated number of new HIV diagnoses were 5,997 95%CI[5,806-6,188] in 2015 and  6,003 [5,751-6,255] in 2016. The estimated numbers of new AIDS diagnoses were  1,092 [1,040-1,144] in 2015 and  863 [771-955] in 2016. The French HIV/AIDS reporting system has changed in 2016. 

Ireland

HIV was made a notifiable disease in September 2011. The HIV reporting system was modified substantially in 2012. AIDS cases and deaths among AIDS cases are now only reported if at the time of HIV diagnosis. HIV diagnoses include a growing proportion of 'previous positive' persons, who are transferring their HIV care when moving to Ireland and tested positive and notified within the Irish system when moving to the country. There was a change in the implementation of the case definition in 2015 (requiring confirmatory testing on a single sample rather than two samples) which resulted in more persons being notified to the surveillance system. 

Italy

New HIV diagnoses were reported by 10 of the 21 Italian regions between 2004 and 2006, 11 regions in 2007, 12 regions in 2008, 18 regions in 2009, and all of the 21 regions of Italy since 2012. Between 2004 and 2011, population denominators are based on the annual resident population in the regions reporting cases. From 2012 the coverage of the surveillance system is national and, thus, the total Italian population is used as a denominator. 

Malta

New HIV reporting system started in 2004

Netherlands

New HIV reporting system started in 2002; 2002 data include many cases diagnosed in previous years.  Data prior to 2002 are from a national cohort of HIV-positive adults receiving antiretroviral therapy; 1999 data include many cases diagnosed in previous years.

Portugal

PT-HIV database is now fully case-based containing details of cases diagnosed from 1983. In 2013 and 2014, the Portuguese HIV/AIDS Programme implemented a strategy to address underreporting and reporting delay, resulting in significant increases of the number of reported cases diagnosed between 1983 and 2012. 

Romania

New HIV diagnoses who have AIDS are reported only in in the AIDS database and AIDS tables.  The total number of new HIV diagnoses for Romania is a sum of the HIV and AIDS case reports for any given year. 

Russian Federation

HIV/AIDS surveillance data are not being reported to WHO by the Russian Federation. In the annual joint ECDC/WHO HIV/AIDS surveillance in Europe reports, published data from the Russian Federal Scientific and Methodological Centre for Prevention and Control of AIDS are included within the other countries’ reported data to provide a more complete presentation of the epidemiology of HIV in the WHO European Region.

Spain

HIV reporting has existed since the 1980s in some of the 19 Autonomous Regions of Spain. For 2003-11 data are available only for 9 Regions: Asturias, Balearic Islands, Basque Country, Canary Islands, Catalonia, Ceuta, Extremadura, La Rioja, and Navarre; since 2004, data are available for 10 Regions (+ Galicia); since 2007, data are available for 11 Regions (+Madrid); since 2008, data are available for 14 Regions (+ Aragón, Castilla-La Mancha and Melilla); since 2009, data are available for  17 Regions (+ Cantabria, Castilla-León and Murcia); since 2012 data are available for 18 Regions (+Valencia). Since 2013 data are available for  all the 19 Regions of Spain (+ Andalucía). Rates based on the corresponding populations for each year. It has not been possible to include data from several regions for AIDS reporting in 2014-2016, rates for those years are based on the corresponding population.

Türkiye

Reported HIV cases exclude persons diagnosed with AIDS at the time of HIV diagnosis. Reported AIDS cases only include people diagnosed with AIDS at the time of HIV diagnosis. 

Turkmenistan

Turkmenistan has only officially reported two cases of HIV since the beginning of reporting, one of whom developed AIDS and both died. 

Ukraine

Data reported from Ukraine exclude Crimea and Sevastopol City for 2014-2016 and parts of the non-government controlled territories for 2015-2016; corresponding population denominators were used to compute rates. 

Uzbekistan

No data have been reported to WHO since 2010.
