Efficacy of ITNs on malaria prevention
New global research highlights the sustained impact of ITNs
The 2024 Malaria Atlas Project analysis confirms that ITNs remain the single most effective malaria prevention tool worldwide, accounting for 72% of malaria cases averted between 2000–2024. The report shows increasing impact over time—even amid rising insecticide resistance—and identifies ITNs as a critical foundation for driving transmission levels low enough for vaccines to achieve maximum effectiveness.
The global efficacy of insecticide-treated nets (ITNs)
ITNs have consistently delivered the greatest impact of any malaria intervention, providing both personal protection and community-wide reductions in transmission. The latest MAP analysis confirms that ITNs continue to perform strongly across diverse settings—even where resistance patterns are changing—making them an essential backbone of malaria control and elimination strategies.
Why strong ITN coverage remains essential
The MAP report highlights that stalled ITN coverage—not reduced ITN effectiveness—is a major factor behind slowing global progress. Achieving and sustaining 80% coverage is essential for:
reducing transmission
protecting vulnerable populations
maximizing vaccine effectiveness
preventing resurgence
Frequently asked questions
What does the new MAP analysis say about ITN effectiveness?
It finds that ITNs were responsible for 72% of all malaria cases averted from 2000–2024, making them the most impactful intervention globally.
Has insecticide resistance reduced ITN performance?
The report shows that ITNs have continued to avert increasing numbers of cases over time. The introduction of new-generation ITNs further strengthens impact.
