Dar es Salaam


Sickle Cell Disease Genomics Network of Africa

Dar es Salaam is home for Muhimbili University of Health and Allied Sciences (MUHAS) and MUHAS Academic Medical Centre where the SickleGenAfrica operates in Tanzania. MUHAS is the first Public University for Health Sciences in Tanzania. The Department of Haematology and Blood Transfusion sits within the School of Medicine which serves as a center for healthcare, research, education and training in Haematology and blood transfusion (H&BT) in Tanzania. The Dar site collaborates with the Sickle Cell Programme within the Department which is responsible for conducting sickle cell related biomedical research, support health care, advocacy and training.
