Health workers are undoubtedly the most important resource that we have in providing and improving the health and chances of survival of children, mothers and their families. In this new report, entitled "No Child out of reach - time to end the health worker crisis", Save the Children calls for urgent action to tackle the problem of the global health worker shortage and to firmly raise the issue on the international agenda. The report highlights the extent of the problem and how the most vulnerable children are denied access to healthcare services and trained healthcare professionals due to a massive shortfall of health workers in some of the poorest countries in the world.
