Sickle cell disease in the Zanzibar Archipelago, the Republic of Tanzania.

The results of the present study support the necessity to introduce large-scale population- -based screening for SCD in the Zanzibar Archipelago, especially in infants whose family members have sickle cell anaemia. The introduction of such a programme will help monitor the number of new SCD cases in the region and may potentially reduce infant mortality due to SCD as well as minimize complications from SCD in older children through the adoption of effective disease prevention measures.
