Vector control for malaria elimination in Botswana: progress, gaps and opportunities.

Area of Science:

• Vector control
• Malaria elimination
• Entomological surveillance

Background:

• Botswana achieved significant malaria control progress through improved case management and vector control interventions like indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs).
• Challenges such as insecticide resistance, outdoor mosquito behavior, and limited community participation hindered malaria elimination goals.
• Lack of entomological data, resources, and intersectoral collaboration impacted the National Malaria Programme (NMP).

Purpose of the Study:

• To analyze vector control challenges and opportunities for Botswana's National Malaria Programme.
• To optimize and augment current vector control interventions for malaria elimination by 2030.
• To provide evidence-based recommendations for achieving malaria elimination targets.

Main Methods:

• Case study analysis of Botswana's National Malaria Programme.
• Review of vector control strategies and their effectiveness.
• Identification of challenges and exploration of opportunities for program enhancement.

Main Results:

• Insecticide resistance, outdoor mosquito activity, and human behavior impede the effectiveness of IRS and LLINs.
• Insufficient entomological data, resources, and community engagement delay malaria elimination.
• Limited operational research and intersectoral collaboration hinder evidence-based decision-making.

Conclusions:

• Timely and quality entomological surveillance is crucial for effective malaria vector control.
• Integrated vector management approaches are essential for optimizing current interventions.
• Strengthening operational research and intersectoral collaboration is vital for Botswana's malaria elimination goal.
