MENTOR’s integrated vector management approach reduces and prevents vector-borne diseases by targeting multiple vectors and integrating various control strategies. This holistic approach increases the effectiveness of vector control interventions in the countries and contexts where we work.
The main benefit of integrated vector management is its ability to target multiple vectors at the same time. Many vector-borne diseases, such as malaria, dengue fever and Zika virus, are transmitted by different vectors. By focusing on a single vector species, control efforts may not effectively address the overall disease burden.
Integrated vector management considers the ecology and behaviour of multiple vectors, which results in a broader, tailored approach to disease control. By integrating control measures that target different vectors, such as mosquitoes and sandflies, we can reduce disease transmission and protect communities more effectively.
Integrated vector management uses a range of tools and strategies to tackle vector-borne diseases. Each tool plays a role within the integrated vector management framework, addressing different stages of the vector life cycle and targeting various points of disease transmission.
These include:
- Indoor Residual Spraying (IRS) is the application of insecticides to indoor surfaces where disease-transmitting mosquitoes’ rest.
- Larval Source Management (LSM) prevents larvae from developing into adults at mosquito breeding sites.
- Social Behaviour Change Communication (SBCC) strategies promote behaviour change, encourage the use of preventive measures and adoption of vector control interventions.
- Entomological Surveillance involves monitoring mosquito populations, their behaviour and insecticide resistance patterns. This helps inform decision-making and improves targeted interventions.
- Long-Lasting Insecticide-treated Nets (LLINs) nets provide physical protection against mosquito bites and kill mosquitoes resting on net surface reducing the risk of vector-borne diseases.
Using these tools within the integrated vector management framework has many benefits:
- By combining different strategies, we can target vectors at multiple stages of their life cycle, interrupting disease transmission more effectively.
- Integrated approaches are shown to have a greater impact on reducing diseases compared to using a single intervention in isolation. For example, combining spraying with net distribution has shown to significantly decrease malaria transmission in various settings.
- Using different tools also allows for synergistic effects, where the combined impact is greater than an individual intervention.
- It promotes sustainable vector control by addressing all vector populations and minimising the risk of insecticide resistance.
Implementing integrated vector management in countries where we work has had a significant impact. Through partnerships with USAID, FCDO, UNICEF and other donors, this strategy has significantly reduced the burden of vector-borne diseases.
