The Robert Koch Institute (RKI) recently published the figures for HIV diagnoses in 2013: the RKI found that the number of diagnoses for gay men remained stable compared to 2012: Nationwide, there is only a slight increase of 27 cases from 1,708 to 1,735. While there were increases in Berlin (with +80) and Hesse (with +22), the number of new diagnoses fell in other federal states.
In total, almost 3,300 heterosexual and homosexual people were newly diagnosed with HIV in Germany in 2013. According to the RKI, there may be various reasons for this increase, such as improved data quality and increased research by the RKI (i.e. the RKI notices more), increased awareness of testing offers (such as testing weeks, which ICH WEISS WAS ICH TU regularly helps to organise) and also an actual increase in new HIV infections.
The RKI, the Federal Institute for Infectious Diseases, publishes the figures on the development of HIV diagnoses - and not on HIV (new) infections. This small but subtle difference is important, as the time of infection and the time of diagnosis could be far apart.
