Haematological study in Cabo Delgado province, Mozambique; sickle cell trait and G6PD deficiency.

A haematological study was done in several villages in the northern province of Cabo Delgado in Mozambique. The prevalence of sickle cell trait (HbAS) was found to be about 4%. The prevalence of G6PD deficiency in males was about 18%. No significant differences were found in haemoglobin values between HbAA and HbAS individuals and between G6PD deficient and G6PD normal individuals. The number of males with both HbAS and G6PD deficiency was not significantly greater than expected.
