Reducing malaria by mosquito-proofing houses.

Sometimes, valuable lessons from history are forgotten, remain unknown, or worse, are ignored. This article reminds us of the pioneering work of Angelo Celli at the end of the 19th century, who demonstrated that people could be protected from malaria by screening their homes against mosquitoes. Since then, public health scientists have continued to show that simple changes in house design have the potential for protecting people against this life-threatening disease. Yet today, this type of intervention remains virtually ignored. The literature reviewed here demonstrates the enormous potential of these methods to reduce malaria, in the hope that it will stimulate scientific debate and further research.
