The use of bed nets and spraying indoor insecticides are key vector control measures in the fight against malaria - but they won't last forever.
Transcript
The use of bed nets and spraying indoor insecticides are key vector control measures in the fight against malaria. Many malaria-endemic countries, like Uganda, have government schemes to recurringly roll out these interventions.
The use of those tools results in a dramatic reduction in malaria transmission: up to 84% fewer cases. But over time, as those tools are rolled out again and again, the impact goes down, ultimately leading to a resurgence.
In five regions of North Eastern Uganda, although bed nets and indoor residual spraying were initially effective, seven years after they started to be rolled out, cases went up by 39% compared to the pre-programme baseline.
This highlights the importance of surveillance of malaria on the ground. But also the age-old fact that one tool for malaria is never enough. The toolbox always needs to be updated.
