Hypothesis
How does the durability and efficacy of PermaNet® 2.0 change after five years of use in a Tanzanian community?
Conclusion
Public health education on bed net use and maintenance is essential for maximizing malaria protection.
Supporting Evidence
- Only 11.7% of the distributed nets were still in use after five years.
- The active ingredient in the used nets was undetectable after five years.
- Mortality rates of mosquitoes were significantly lower for used nets compared to new ones.
Takeaway
This study looked at how well mosquito nets work after being used for five years. It found that many nets were not used anymore and didn't work as well.
Methodology
The study used cone bioassay tests with different mosquito species to assess the efficacy of the nets.
Limitations
The study only evaluated one brand of net and did not account for all community factors affecting net use.
Participant Demographics
Households in lower Moshi, north-eastern Tanzania.
