• In 2004, with CDC support, the Ministry of Health established a centralized, coordinated National Blood Transfusion Service. In 2013, CDC conducted a blood needs survey in Tanzania which found an increase in overall blood collection and a decrease in units testing positive for HIV. CDC financial support for blood safety ended in 2015 and operational support transitioned to the Ministry of Health. CDC continues to provide technical assistance in three areas: the national blood electronic computer system, internal and external quality assurance, and support for national accreditation for zonal blood centers.
