Saharan Africa received insecticide-treated mosquito nets to protect them from mosquitoes that carry of the virus. Indoor spraying has also protected 75 million people, or 10 percent of the population at risk in 2009, the report said. The number of deaths due to malaria is estimated to have decreased from 985,000 in 2000 to 781,000 in 2009. While progress has been made in most countries, resurgences in cases were observed by the WHO in parts of at least three African countries-Rwanda, Sao Tome and Principe, and Zambia.
