CDC Activities in Tanzania

US President's Malaria Initiative

CDC supports malaria control efforts for the mainland National Malaria Control Programme and the Zanzibar Malaria Control Programme as part of the US President’s Malaria Initiative (PMI). Since 2005, this effort has produced phenomenal gains in access to malaria prevention and treatment interventions in Tanzania and across the Zanzibar Archipelago. For more information on PMI activities in Tanzania, see www.pmi.gov.

CDC/IHRDC Malaria Program in Tanzania

Tanzania

In addition to the agency’s key role in guiding and implementing PMI in the United Republic, CDC and the Ifakara Health Research and Development Centre (IHRDC) have collaborated on a series of cooperative agreements since 2000. The CDC/IHRDC Malaria Programme in Tanzania has emerged as a globally recognized leader in implementation and applied research to guide malaria control programs for both the mainland and Zanzibar Ministries of Health and Social Welfare and public health programs across the continent.

Between 2000 and 2006 the CDC/IHRDC Malaria Programme in Tanzania achieved the following milestones:

• Completed the first programmatic implementation of artemisinin-containing combination therapy (ACT) in tropical Africa, delivering over a million treatment doses of highly effective malaria treatment in an isolated rural district for more than 4 years.
• Established the complementary role of free and market-based strategies for delivering insecticide-treated mosquito nets (ITNs) for malaria prevention.
• Characterized the public- and private-sector markets for malaria treatment and demonstrated how national policies can affect the equitable access to treatment for impoverished rural communities.
• Documented the distribution of drug-resistant strains of malaria across rural Tanzania and the rest of Africa.
• Established the relative contribution of diagnostically confirmed malaria among patients presenting to first-line health facilities and drug stores in rural Tanzania.
• Completed the first national survey on quality of antimalarial drugs available in the retail sector and established the extent of distribution of artemisinin monotherapies in urban Dar es Salaam.
• Contributed to a global model of malaria risk, coordinated by Oxford University.
• Established best practices for achieving high adherence to complex 3-day treatment regimens with at least 2 ACTs.
• Compared 3 possible regimens for the intermittent preventive treatment of malaria in pregnancy.
• Established the impact of ACT and ITNs on nearly eliminating malaria transmission in the Zanzibar Archipelago.
• Provided detailed implementation evidence for the roll-out of rapid diagnostic tests for malaria in rural Africa.
• Demonstrated how interventions to improve the care of severely ill children could be effectively implemented in the context of the Integrated Management of Childhood Illness.
• Monitored the costs and policy implications of delivering ACT as routine first-line treatment for malaria at district and national levels.
• Elaborated the health-equity implications of delivering malaria treatment and prevention.

These activities were completed as part of the Interdisciplinary Monitoring Project for Antimalarial Combination Therapy in Tanzania (IMPACT-Tz), supported by CDC, the US Agency for International Development, and the Wellcome Trust. In addition to IHRDC, key partners included the Australian National University, the London School of Hygiene and Tropical Medicine, and the Swiss Tropical Institute.

Since the completion of IMPACT-Tz, the CDC/IHRDC Malaria Programme in Tanzania has continued to support the Malaria Control Programmes in both Ministries by providing:

• Funding for in vivo and in vitro assays of antimalarial drug resistance.
• Opportunities for Tanzanian scientists to train alongside US-based laboratorians.
• Support for quality assurance of rapid diagnostic tests for malaria.
• Technical guidance for the operational research component of mainland Tanzania’s Round 4 award from the Global Fund to Fight HIV/AIDS, Tuberculosis and Malaria (GFATM).

Beginning in 2008 the CDC/IHRDC Malaria Programme will begin to implement an evaluation of mainland Tanzania’s Round 7 award from GFATM to explore the impact of introducing rapid diagnostic tests for malaria and a highly subsidized ACT in the private retail sector. This will be done collaboratively with the ACT Consortium at the London School of Hygiene and Tropical Medicine, through a grant from the Bill and Melinda Gates Foundation. CDC and IHRDC are looking forward to future collaborative opportunities along this model.
