The overall objective of this project is to contribute to improving access to national healthcare for migrants and mobile populations (MMPs), particularly women, in Cambodia, with particular focus on the three major infectious diseases (HIV/AIDS, Tuberculosis, and COVID-19). The project will strengthen the capacities and responses of key government partners in providing targeted interventions to support access to health care system to MMPs. The project also focuses on public outreach and will build greater awareness and willingness among MMPs to utilize prevention methods and access health services.
