Migrants in the United Republic of Tanzania face barriers in accessing services, particularly the most vulnerable migrants, such as informal workers, irregular migrants, and migrant victims of violence or exploitation. The conditions and circumstances surrounding the process of migration can pose risks to the physical, mental and social well-being of migrants. The migration process is thus an important social determinant of health, for the migrants and communities with which they interact. The project’s objective is to contribute to strengthened public health measures and reduced health vulnerability among vulnerable migrants and migration affected communities in North-western United Republic of Tanzania. The above objective will be achieved through the following outputs: 1) The provision of gender sensitive health services is increased through mobile and community outreach services in the intervention areas, 2) The capacity of health facilities and service providers along the mobility continuum is increased in the regions of Kigoma, Kagera, Geita and Mwanza, 3) Health seeking behaviour is increased through demand creation activities, 4) The preparedness and response capacity of personnel at Points of Entry and Exit (PoE) is strengthened, 5) Cross-border coordination in the regions of Kigoma, Kagera, Geita and Mwanza is strengthened through the establishment of cross-border coordination committees, 6) Gender sensitive Risk Communication and Community Engagement (RCCE) activities are scaled up along the mobility continuum, and 7) Infection prevention and control measures are enhanced in under-supported locations including health facilities and communities in Kigoma, Kagera, Geita and Mwanza.
