Integrated vector control

Worker fumigating

Vector control for the prevention and elimination of NTDs has received inadequate attention in recent years. However, following the emergence of Zika virus and the rise and spread of dengue fever, there is a growing interest in the potential that existing and future vector control interventions could have for tackling NTDs.

This was explicitly recognised in the 2017 WHO 4th NTD Progress Report, and at the World Health Assembly in May when the WHO Global Vector Control Response 2017-2030 was ratified – providing the global strategy and framework for effectively scaling up integrated vector control.

There is an urgent need to raise awareness of vector control amongst policymakers, donors, investors and international stakeholders in order to mobilise governments and communities and commit the required resources to tackle vector-borne NTDs.

Some of the major gaps in vector control include:

  • There is a need for strong advocacy to make the case for investing in integrated vector control, advocating for greater financing of vector control, encouraging endemic governments and organisations in all sectors to take action, and supporting communities to hold policymakers to account.
  • There are significant gaps in the evidence base for vector control, including which vector control strategies are effective and sustainable, in what contexts, and to what extent these are cost-effectiveness.
  • We need to better understand why vector-borne diseases are spreading and increasing. This includes changing vector habitats, rapid urbanisation, the impact of climate change, and the complex interactions between vectors and humans.
  • We need to learn lessons from vector control interventions to combat malaria, onchocerciasis and Chagas disease
  • There is limited public health entomology capacity and poor health systems infrastructure in many endemic countries, and attrition of trained staff is high.
  • Disease and vector surveillance systems in many endemic countries are also fairly limited.
  • Community participation in integrated vector control is crucial, therefore there is a need to identify concrete strategies for ensuring long-term, sustainable community engagement in vector control.
     

Functions of the IVC group

  1. To drive the development and implementation of the NNN’s strategy on integrated vector control for NTDs.
  2. To support the achievement of the WHO Global Vector Control Response 2017-2030 in relation to NTDs, including entomological and surveillance capacity building.
  3. To provide a forum that brings together non-governmental organizations, scientists, academics, and advocacy groups to share evidence and learnings, identify gaps and problems, and develop solutions and novel approaches to the challenges in integrated vector control and surveillance.
  4. To coordinate advocacy activities to support the scale-up of integrated vector control and achievement of the WHO Global Vector Control Response 2017-2030.
  5. To align with and contribute to the NNN Framework for Engagement and its objectives
  6. To ensure the Network’s support to the WHO NTD Roadmap is aligned with NNN objectives.
  7. To ensure that NNN is represented in relevant forums related to integrated vector control and share relevant information with NNN members.
  8. To identify, and plan for, an annual programme of activities that deliver, or enable the Network to deliver on, on the NNN strategy for integrated vector control.
  9. To report back to the Members at the Annual Conference on progress.
