ESTICOM aims to strengthen the community response and raise awareness about the persisting legal, structural, political and social barriers hindering a more effective response to the syndemics of HIV, hepatitis viruses B and C, and other STI among MSM. The main activities include surveys among MSM (EMIS2017) and Community Based Health Workers (ECHOES) as well as a training programme for Community Health Workers intended to be adaptable for all EU countries.
