U.S. Health Secretary Dr. Louis Sullivan and a senior Agency for International Development official cut short an eight-nation tour of Africa because of the gulf war, Sullivan said.

Sullivan and AID administrator Dr. Ronald Roskens were on a presidential mission to study health problems affecting African children. They had been to Ivory Coast, Nigeria, Malawi, Uganda, South Africa and were visiting Zimbabwe when they were recalled to Washington on Thursday. Visits to the West African nations of Mali and Senegal were canceled.
