Within the framework of the ESTICOM project a training programme for MSM Community Health Workers will be developed and piloted in ten European countries. Our preliminary definition of MSM Community Health Workers includes all people who currently provide sexual health services in a community setting directly to gay, bisexual and other men who have sex with men (MSM). Sexual health services for us include services related with HIV/STI and/or viral hepatitis (Hep B & C), drug use, and mental health.
