The Minister of Health and Sanitation says no nation can prosper with a poor healthcare delivery service to its people. Zainab Hawa Bangura made the statement while addressing members of the Nurses and Midwives Board of Sierra Leone at the Youyi Building in Freetown.   The minister said the board has both moral and ethical responsibility to ensure that the policy and guidelines set by the government are efficiently implemented. She described nursing and midwifery as noble professions and called on the health workers to restore the dignity and credibility the professions once enjoyed.   Mrs. Bangura also urged the board to develop proposals that would make inroads for the growth of the health sector of the country. She expressed her determination to increase the number of nurses in a bid to ensure more efficient service delivery.   Reverend Gloria Betts Cole is former president of the West African College of Nursing and a member of the board.   She expressed disappointment over the delay in absorbing nurses into the civil service and what she called the proliferation of mushroom nursing schools in the country.   She said nursing required intelligent, trained and qualified personnel to handle human lives.
