A World Health Organisation representative, Custodia Mandlhate, said the 21 percent HIV prevalence in the province was being influenced by economic migration to South Africa and Botswana.
Harare had the lowest cases with 13 percent. HIV cases were higher in urban areas with 17 percent compared to 15 percent in rural areas. The national average was 15 percent.
Mandlhate attributed the reduction of cases to the AIDS levy.
