NAPS key groups

NAPS focuses primarily on population groups that have an increased risk of infection with sexually transmitted pathogens and on people who have already been infected. 

NAPS designates population groups that have an increased risk of infection with sexually transmitted pathogens or who are already living with a sexually transmitted infection as key groups.  Their composition can change depending on the epidemiological situation. People can also belong to several key groups at the same time.

According to current knowledge, the following people belong to key groups addressed by NAPS (in alphabetical order):

  • Gay, bisexual, queer and other men who have sex with men (MSM)

  • People from countries with an increased prevalence of sexually transmitted pathogens

  • People in prison

  • People who inject, inhale or sniff drugs
