For the past 35 years, SIDC has been involved in providing a comprehensive package of services within and outside its center (through its mobile unit). These services include mental health, reproductive and sexual health, prevention and treatment for HIV and other sexually transmitted infections, drug addiction and related harm reduction services and materials in addition to legal services. Moreover, SIDC was among the first NGOs that integrated a cross-cutting program related to stigma reduction in all of its programs. SIDC built networks and partnerships and developed the capacities of various stakeholders and key players of the HIV response including media representatives, religious leaders, police officers, health and social care service providers, workplace owners and employees among others. Fifteen years ago, SIDC launched an outreach program in Lebanon based on peer approach reaching out to injecting drug users (IDUs), sex workers, LGBTQIA+ and other people at risk to deliver services related to HIV/HBV/HCV/ Syphilis through a mobile unit. SIDC continues to be a pioneer in this area at the national and regional levels. SIDC services and programs reach to adolescents and youth at risk, males and females sex workers, LGBTQIA+, people living with HIV (PLHIV) and People who use Drugs (PWUDs), marginalized girls and women, domestic workers, displaced persons, refugees and prisoners.
In addition, SIDC has been advocating and defending the rights of all of the aforementioned marginalized groups through documentation of violations at various levels, providing access to reliable information, relevant skills, and adequate services and enabling these groups to increase their capacity to claim their rights.
