VectorLink Tanzania supports the implementation of IRS in Mainland Tanzania and Zanzibar. It aims to move the country toward PMI’s goal of halving the burden of malaria in 70 percent of at-risk populations in sub-Saharan Africa. This is consistent with the 2018–2020 malaria strategy of the Mainland Tanzania NMCP. That strategy seeks to ensure that Tanzanians have access to good-quality, effective, safe, and affordable malaria interventions through timely and sustainable collaborative efforts with partners and stakeholders at all levels. VectorLink Tanzania also supports the work of the Zanzibar Malaria Elimination Program (ZAMEP) to achieve malaria elimination in Zanzibar by 2023.

IRS in Tanzania Mainland

In 2018/2019, under the PMI VectorLink Tanzania project, IRS was conducted in seven Mainland Tanzania districts, targeting 516,396 structures using 154,744 sachets of the clothianidin insecticide (SumiShield 50WG) from October 24 – November 23, 2018. A total of 501,584 structures were sprayed out of 525,222 structures found by spray operators (SOPs) in the targeted districts, accounting for a coverage rate of 95.5%.

IRS in Zanzibar

In 2018/2019, under the PMI VectorLink Tanzania project, IRS was conducted in ten districts of Zanzibar (Pemba and Unguja), targeting 88,355 structures using 27,193 bottles of pirimiphos-methyl, (Actellic 300CS) from February 23 – March 17, 2019. A total of 94,339 structures were sprayed out of 99,126 structures found by SOPs in the targeted districts, accounting for a coverage rate of 95.2%.

In 2019/2020, VectorLink Tanzania conducted IRS in six Mainland Tanzania districts and 10 selected shehias in Zanzibar, targeting 512,539 structures and using 154,964 units of clothianidin (SumiShield™ 50WG) and pirimiphos-methyl (Actellic 300CS) from October through November 2019 and in March 2020. The March IRS campaign was stopped early at the direction of the Government of Tanzania because of the COVID-19 pandemic. By that time the project had already achieved a coverage rate of 93.7 percent: 471,622 structures were sprayed out of 503,567 structures found by spray operators in the targeted districts.

In its third year of implementation, VectorLink Tanzania will work with the NMCP & PORALG in Tanzania Mainland, ZAMEP in Zanzibar, and regional administrations and local governments in these locations to spray 519,408 targeted structures in the six districts in Mainland Tanzania and 45,965 structures in selected shehias in Zanzibar. The project will use pirimiphos-methyl (Actellic 300CS) for a few areas in Bukombe from the existing stock. In Kigoma we will use clothianidin (SumiShield™ 50WG) insecticide, and in Biharamulo, Ukerewe, and the remainder of Bukombe we will use Fludora® Fusion. In addition, PMI VectorLink will distribute 2,252,774 ITNs through the School Net Program (SNP), 1,964,186 ITNs through reproductive and child health services (RCH) in health facilities -mainland, and 288,656 ITNs through antenatal care/expanded program on immunization (EPI) or community channels in Zanzibar. The project’s primary IRS objective is to reach a minimum coverage of 85 percent of the structures found in each IRS district by implementing high-quality IRS operations. The project’s primary ITN objective is to distribute ITNs through SNP, RCH, and community channels in selected regions with high malaria prevalence in the Mainland and Zanzibar.

In addition to spraying, and delivery of ITNs through the SNP and to health facilities in Zanzibar, in Year 3 the project will carry out the following activities:

  • Conduct logistics assessment in all districts, and arrange all procurement, shipping, delivery, and storage of IRS commodities.
  • Strengthen the IRS logistics and warehousing system through enhanced forecasting of IRS needs, training, and supervision.
  • Conduct environmental compliance assessments (Environmental Audit and Environmental Social and Impact Assessment) in consultation with PMI and the National Environmental Management Council.
  • Coordinate community mobilization activities in collaboration with stakeholders to raise awareness of IRS and to encourage beneficiary and stakeholder ownership.
  • Recruit IRS personnel from the beneficiary communities, e.g., spray operators, mobilizers, team leaders, and supervisors, in collaboration with district offices. The recruitment of spray operators from their communities will bring a sense of ownership and play a big role in sensitizing the communities earmarked for spraying.
  • Collaborate with other partners on information, education, and communication (IEC especially with the social and behavior change communication (SBCC) units of Ministry of Health, Health Promotion Section, NMCP, and ZAMEP, as well as USAID Tulonge Afya activity, to ensure the right messages are designed and delivered to the beneficiaries of IRS and ITNs.
  • As part of sustainability, build capacity at the national, regional, district, and local levels to manage IRS operations, including planning, spraying, resource allocation, and monitoring and evaluation (M&E) in order to enhance country ownership and move towards the goal of gradually transitioning activities over to the government.
  • Conduct training with a focus on IRS supervision, spray techniques, and household preparation to improve the overall quality of spraying.
  • Conduct robust M&E of project activities to ensure alignment with set targets and objectives.
  • Mainstream gender equality and female empowerment by ensuring women’s meaningful participation across project activities.
  • Ensure safe and correct insecticide application, thus minimizing human and environmental exposure to IRS insecticides, in compliance with the Pesticide Evaluation Report and Safer Use Action Plan and Supplemental Environmental Assessment (SEA).
  • Scale up VectorLink Collect mobile data collection by spray operators from the 2019/2020 implementation.
  • Scale up the use of numbered spray operator forms for all campaigns from the 2019/2020 pilot, including IRS cards.
  • Use the KoboCollect application to document environmental compliance incidents and report on them during the campaign for timely follow-up.
