Health interventions are unlikely to succeed if they are not embedded in broader efforts to respect the rights of their citizens and serve their basic needs. In the case of access to a skilled professional at birth, for example, reaching the projected value for MDG 5 has been estimated at $8 billion for the region, though if the off-track countries are to close their gaps they would need a further $13 billion. Similarly, closing the gap for safe water supplies would cost an additional $2 billion and for safe sanitation an additional $8 billion.
