Treated Mosquito Nets Save Children's Lives

In sub-Saharan Africa use of insecticide treated nets to prevent the bites of malaria parasite-carrying mosquitoes has been accompanied by significant reduction in child deaths.In a multi-country analysis led by Stephen Lim from the Institute for Health Metrics and Evaluation based in Seattle, USA, and published in this week's PLoS Medicine, the authors analyzed and combined data from 7 surveys in 7 sub-Saharan African countries to show that children living in a household that owned an ITN were 20% less likely to have malaria parasites in their blood (parasitemia). Importantly, the authors found a 23% reduction in child deaths (aged between 1 month and 5 years) associated with family ITN ownership based on 29 surveys in 22 sub-Saharan African countries. These findings support the widespread provision of ITNs as a key intervention in controlling malaria.
The authors say: "Our findings across a number of sub-Saharan African countries were highly consistent with results from previous clinical trials."
They continue: "These findings suggest that the recent scale-up in ITN coverage has likely been accompanied by significant reductions in child mortality and that additional health gains could be achieved with further increases in ITN coverage in populations at risk of malaria."
In an accompanying Perspective, Thomas Eisele from Tulane University School of Public Health and Tropical Medicine in New Orleans, USA and Richard Steketee from PATH in Seattle, USA say: "As Lim and colleagues suggest, continued scale-up of long-lasting ITNs must be a cornerstone of this effort and there are still lives to be saved with this intervention."
