IntroductionHaemophilia is a rare hereditary haemorrhagic disease caused by coagulation factor VIII (haemophilia A) or IX (haemophilia B) deficiency. Very few data exist on this disease in Congo. This survey aims to describe the epidemiological and clinical aspects of the children affected.Materials and methodsA descriptive cross-sectional study was carried out in the haematology department of the Brazzaville University Hospital over a period of two years. Children (under 18 years of age) with haemophilia and with a factor VIII or IX level less than or equal to 30% were identified. The parameters analysed included age, diagnostic delay, type and severity of haemophilia, type and frequency of bleeding manifestations, complications and history of transfusion.ResultsNineteen patients were identified with an average age at diagnosis of four years.
