Human beings are not property. On the International Day for the Abolition of Slavery, let us reaffirm the inherent dignity of all men, women and children. And let us redouble our efforts so that the words of the Universal Declaration of Human Rights - 'no one shall be held in slavery or servitude' - ring true.

World Health Day is an opportunity to highlight the problem, but above all, to stimulate action. It is an occasion to call on all partners - governments, international donors, civil society, the private sector, the media, families and individuals alike - to develop sustainable activities for the survival, health and well-being of mothers and children. On this World Health Day, let us rededicate ourselves to that mission.

Let us work in partnerships between rich and poor to improve the opportunities of all human beings to build better lives.
