In Germany, data on drug-related infectious diseases are available from the registers at the Robert Koch Institute, which are complemented by data from other, usually regional, sources.
The number of new cases of human immunodeficiency virus (HIV) infection attributable to injecting drug use showed downward trend between 2000 and 2009, then stabilised between 2010 and 2012. Since then, an increase has been reported. Around 5 % of new cases of HIV infection are linked to injecting drug use in Germany. A cluster of cases of HIV infection in Bavaria (2016) has been associated with the use of synthetic cathinones.

Reliable information on the mode of transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV) was available for only a minority of cases; nevertheless, data suggest that injecting drug use remains a significant risk factor for HCV infection. In 2017, around 80 % of newly diagnosed cases of HCV infection with known mode of transmission were linked to injecting drug use. Among newly diagnosed cases of HBV infection in 2017 with available information, the proportion linked to injecting drug use was 23 %.
A study covering 2011-14 indicated large geographical variations in rates of HIV, HCV and HBV infection among people who inject drugs from eight cities, which is attributed to different use patterns, age structures and local conditions.
