Abstract
The Tanzania Vector Control Scale-up Project (TVCSP) goal is to contribute to the reduction of the burden of malaria by interrupting malaria transmission through Indoor Residual Spraying (IRS) and the prevention of adverse effects of malaria epidemics through blanket and focal spraying activities. TVCSP works with regional and district governments and health structures and with communities to implement IRS, entomological and environmental monitoring and epidemic malaria surveillance activities in Mainland and Zanzibar. The TVCSP has seven areas of focus: (1 )IRS operations; (2) environmental compliance; (3) support to entomological monitoring systems; (4) support to epidemiological surveillance and response; (5) capacity building and sustainability; (6) crosscutting activities (gender and cross-border collaboration); and (7) monitoring and evaluation. The TVCSP mid-term evaluation's overall purpose is: (1) to determine the extent to which the Tanzania TVCSP objectives and key result areas are being met; (2) to document lessons learned to inform the second phase of the project; and (3) to assess the various approaches used by the TVCSP to determine what is working in order to achieve the intended results. A major achievement of TVCSP is that IRS is acknowledged by malaria stakeholders, notably including community members, to have contributed to the overall reduction in malaria transmission and morbidity on Mainland and in Zanzibar. Specific evaluation findings, conclusions and recommendations are provided with detailed analysis for each evaluation question. (Excerpt, modified)
