Mobility remains a key issue across Africa. The WDR (2009) identifies three key sources for effective integration: institutions, infrastructure, and interventions. Infrastructure includes systems that facilitate the geographical movement of goods, services, people, and ideas - such as roads. The reality of a mobile clinic therefore relies heavily on having the infrastructure to support flexibility, mobility, and frequent movement.  Mobile clinics still won’t be able to reach all patients that need their help; public investment is required into infrastructure such as roads and railways first. The project can only work if mobile clinics are able to be mobile. Further, even if they are mobile it doesn’t necessarily ensure people become ill when the medical officer happens to be visiting.
