Efforts to improve water, sanitation and hygiene interact with each other to boost overall health. Access to sanitation, such as simple latrines in communities, prevents drinking water contamination from human waste and reduces infections. High-tech public health measures are not necessarily the best: frequent hand-washing with soap and safe storage of drinking water are high-impact practices.
Environmental management effectively lowers the rates of malaria and other diseases spread by insects and prevents death. These measures include eliminating habitats - such as standing water - for breeding, and screening doors and windows for protection from mosquitoes.
I hope this helps
